Chapter 1. Objectives of this Guide
The objective of the Red Hat Style Guide is to help authors communicate information in a clear, transparent fashion, and to facilitate consistency in tone and delivery. We write documentation for a variety of audiences, across multiple geographies and with very different skill sets. We write for end users as well as expert users. Red Hat documentation is:
- Accurate and consistent
- Readable, with a score of 60-70 on the Flesch–Kincaid reading ease scale.
- Comprehensible, with a fog index of 9-12, using the Gunning fog index.
- User focused, providing information without patronizing the reader, or making presumptions about their skills.
Readability
Technical documents should be readable by the targeted audience. In this instance, we expect our audiences to have the minimum reading and comprehension level of an eighth-grade student, of an age between 14 and 15 years. The Flesch-Kincaid and Gunning Fog index provide measurable grades. A Red Hat guide should have a Gunning Fog index of 9-12.
Chapter 2. Grammar
This section contains information on a few common grammar topics. For subjects not covered here, consult The Chicago Manual of Style, 17th Edition.
2.1. Active Voice
Use the active voice ("Type ... to start Linuxconf.") rather than passive ("Linuxconf can be started by typing...") whenever possible. Active voice makes for more lively, interesting reading. It is more compelling than passive voice and helps to reduce word count.
This does not mean that the passive voice is forbidden. There are situations when using the passive voice is appropriate, such as release notes, technical notes, and similar material.
For example, the sentence, "The Developer Center, a site for reference material and other resources, has been introduced to the OpenShift website." reads better than
"The OpenShift website introduces the Developer Center, a site for reference material and other resources." Here, the passive voice is better because the important issue ("The Developer Center") is the subject of the sentence.
You can also use the passive voice to front-load important keywords in key areas of your content, such as the title, heading, or at the beginning of a paragraph or sentence. You need to make these decisions on a case-by-case basis, weighing the importance of front-loading keywords against content that is readable (that is, not awkward sounding). Consider the following two examples:
Example 2.1. Active Voice
"Dutch hosting provider Oxilion launches public cloud service based on Red Hat Enterprise Virtualization."
Example 2.2. Passive Voice
"Public cloud service based on Red Hat Enterprise Virtualization launched by Dutch hosting provider Oxilion."
2.2. Agreement
In grammar, agreement occurs when specific parts of a sentence are coordinated; that is, they agree in number and gender.
There are two forms of agreement: subject-verb agreement and pronoun-antecedent agreement. Subject-verb agreement is pretty rudimentary, and is not discussed here. Pronoun-antecedent agreement can be a little more problematic, so...
2.2.1. Pronoun-antecedent agreement
A pronoun is a word that is used in place of a noun (for example, I, he, she, it). An antecedent is a word or phrase to which the pronoun refers.
When you are comfortable with subject-verb agreement, pronoun-antecedent agreement often follows as a matter of course.
The following is an annotated roundup of pronoun-antecedent rules:
Singular and Plural Nouns
A singular pronoun refers to a singular antecedent; a plural pronoun refers to a plural antecedent. For example:
- The CD spins in its caddy. (The singular third-person pronoun "its" refers to the singular antecedent "CD".)
- The developers checked their work. (The plural third-person pronoun "their" refers to the plural antecedent "developers".)
Collective Nouns
When collective nouns are used as antecedents, use singular or plural pronouns, depending on the sentence's meaning. For example:
- Microsoft seems second to none in its marketing skills. (The collective noun "Microsoft" takes the singular pronoun "its" because the collective noun refers to the group as a whole.)
- The developers were asked for their preferences. (The collective noun "developers" takes the plural pronoun "their" because the reference is to the individuals of the group.)
2.3. Using Who, Whom, That, and Which Correctly
Use "whom" or "who" to introduce a qualifying phrase when the antecedent is a person. Use "that" or "which" when referring to a thing. Use "which" or "that" to introduce a qualifying phrase when the antecedent is a concept or an object. Who, whom, that, and which are known as "relative pronouns."
Use the following as guidelines:
Examples:
- The jewel case, which once held the CD, was broken recently.
- The CD that I received for my birthday is defective.
- Edward C. Bailey, who wrote "Maximum RPM,"...
- The company that published "Maximum RPM" was...
- This book belongs to whomever purchased it last week.
- Who ate all the cereal?
- To whom should I address the letter?
- The desktop that was designed by Earl is not called GNOME.
- The GNOME developers who worked on the desktop are...
- The GNOME developers to whom I owe my gratitude are...
Note
To help you choose between who and whom, substitute the person about whom you are speaking with either him or he.
- If your restatement contains him, her, them, me, or us, then use whom or whomever. "I'm giving the book to him." "To whom am I giving the book?"
- If the restatement contains the word he, she, they, I, or we, then use who or whoever. "Do you think he would mind?" "Who do you think would mind?" "She's walking in the door." "Who's walking in the door?"
2.4. Sentence Structure
A sentence is one, complete thought. A sentence expresses something about a subject (a person, place, or thing) and a verb (what the subject is or does).
The following are things to consider when constructing sentences:
Sentence Length
Try not to pack too much information into one sentence. Keep it short. For example, the following sentence is a good example of how not to write:
The button, which you can find in the bottom left corner of your screen (also activated by the "Windows key" on your keyboard, the one between the Ctrl and Alt keys), provides a central starting point for applications and tasks, and can be customized according to your individual preferences so that it presents menu items relevant to you instead of presenting the standard items that come with the default installation of the operating system, items which, in my opinion, are irrelevant for most users these days who really only need access to an internet browser such as Google Chrome or Mozilla Firefox.
Run-on Sentences
Two or more complete ideas that are joined without punctuation create a run-on sentence (also called a fused sentence). The sentence does not have to be long to be a run-on sentence, although the longer the sentence the more difficult it is to read. You can:
- Separate independent clauses with a period. Doing so will form two sentences out of one.
- Use semicolons to form a compound sentence. Think of a semicolon as an extended breather; longer than a comma.
- Insert a coordinating conjunction, such as "and" or "but", between the independent clauses to form a compound sentence. For example, "The process will start, but it will produce an error."
- Insert a subordinating conjunction, such as "although" or "because", which will form a compound sentence with a subordinate clause. For example, "Although the process will start, it will produce an error."
Table 2.1.
| Example | Improvement |
|---|---|
| The CDs both of which belonged to the developers were in the test lab. | The CDs, both of which belonged to the developers, were in the test lab. |
| To access your programs click the button. | To access your programs, click . |
| The CDs, both of which belonged to the developers, were in the test lab, because they were the only available CDs for the new release, the developers were anxious about keeping them clean. (This sentence exhibits a comma splice which is also often regarded as a run-on sentence.) | The CDs, both of which belonged to the developers, were in the test lab. Because they were the only available CDs for the new release, the developers were anxious about keeping them clean. |
Sentence Fragments
A sentence fragment is an incomplete sentence. For example, "We will release no upgrade before its time." is a complete sentence, whereas in "We will release no upgrade. At least, before its time." the second of the two sentences is a fragment. Repair sentence fragments by making them complete sentences.
Note
Read your sentences aloud, as if each sentence were the *only* sentence on a piece of paper. If you hear a sentence that does not make any sense by itself, then it is probably a sentence fragment.
Telegraphic Style
Extreme cases of word economy can result in a telegraphic style, omitting words that can clarify the meaning of a sentence, such as articles, prepositions, and verbs used with gerunds.
This problem is often encountered in the Revision History. It is important that wording in the Revision History is clear for translators and customers to understand.
Table 2.3.
| Example | Improvement |
|---|---|
| Minor revision - missing element items | Minor revision - added missing element items |
| Some further work required to avoid 404s at lower levels of the SDK. | Some further work required to avoid 404 errors at lower levels of the SDK. |
Verbosity
Avoid unnecessary words. Keep it succinct.
Table 2.4.
| Example | Improvement |
|---|---|
| The individual member of the social community often receives his information via visual, symbolic channels. | People read. (Translation by Richard Feynman.) |
Word Order
When two or more correct arrangements are possible, choose the order that will create the least ambiguity. Generally, this is the standard subject-verb-object, with modifiers before or immediately following what they modify.
Table 2.5.
| Example | Improvement |
|---|---|
| To update the address lists may be your primary concern. | Your primary concern may be to update the address lists. |
2.5. Avoiding Ambiguities
- Capitalizing Proper Nouns
- In some cases it is not clear if a term refers to a concept or a proper noun or product name. By using the correct capitalization, you will help translators identify untranslatable proper nouns and Red Hat product names.
Table 2.6.
Example Improvement This property must be enabled when you are using CTDB in a Windows domain or in active directory security mode. This property must be enabled when you are using CTDB in a Windows domain or in Active Directory security mode. - Homographic Verbs
- The verb "may" can be used to express possibility as well as to grant permissions. Similarly, "should" can be used to make recommendations as well as to express obligation or expectation. A sentence containing one of these verbs often has a double meaning. Avoid these types of words.
Table 2.7.
Example Improvement The next()method should returnnullto indicate the end of results.The next()method is expected to returnnullto indicate the end of results. OR Thenext()method must returnnullto indicate the end of results.It may be held in memory. It can be held in memory. OR It might be held in memory. - Homonymity
- When a single term has multiple meanings, be explicit in order to differentiate between them.
Table 2.8.
Example Improvement Tab through the dialog box. Set the tab. Move the tab on the ruler. How to show or hide tabs. Select the tab. Use the tab key to move through the dialog box. Set the tab stop. Move the tab mark on the ruler. How to show or hide tab characters. Select the tab in the dialog box. To create another administrator, click on the menu. To create another administrator account, click on the menu. OR To set privileges for another administrator, click on the menu. Note
See also Section 5.2, “Grammatical Genders”. - Invisible Plurals
- Some two-word phrases (noun + noun) do not clarify whether the first noun is singular or plural.
Table 2.9.
Example Improvement Once the file retrieval has been completed, you are ready to restart your system. After the files have been retrieved, you can restart your system. - Synonymity
- Sometimes multiple terms have a single meaning. If terms are used inconsistently, users (and translators) will assume they refer to different things. It is best to use a single term for a single concept throughout.For example, "Administration GUI" and "Administration Console" could both be used to refer to a single application or to different applications. For this reason it is important that writers choose the most suitable term for each situation and use it consistently.
2.6. Easily Confused Words
This section identifies some easily confused words and how to choose the correct term for your situation.
Affect and Effect
Each of these words can be used as a verb or a noun, but they are not always interchangeable.
- affect
- n. Refers to the emotional impact of an action. Unless you are writing a psychology article, this is unlikely to be the choice for you.vb. Means to have an influence on something, or to cause something to change.
- effect
- n. Refers to the result of some action. For example, "the team members discussed the effect of the new policy on their working conditions."vb. Means to produce a result, or to cause something to happen. For example, "the CEO claimed that the new policy would effect a positive economic outcome."The use of "effect" as a verb is less common than the use of "affect," and there are usually alternatives that are clearer. For example, "the CEO claimed that the new policy would produce a positive economic outcome."
Assure, Ensure, and Insure
These are relatively easy to get right, but here are some quick definitions.
2.7. Contractions and Abbreviations
Do not use contractions in Red Hat documents. For example, do not use "can't," "don't," "won't," and similar examples. Always write out in full. Take care also with abbreviations; replace "e.g." with "for example," and replace "i.e." with "that is," and so on. See The IBM Style Guide for full details.
2.8. Punctuation
This section contains information on common punctuation topics. For more information, consult The Chicago Manual of Style, 17th Edition.
2.8.1. Colons and Semicolons
Current standards allow the use of a colon or semicolon in a range of different circumstances. Some of these are described in the following sections.
To relate clauses:
The following sentences show a connection or shared theme between two clauses, or use the second clause to reiterate or amplify the idea in the first clause:
- They had been writing code all night: this could explain their bloodshot eyes.
- They had been writing code all night; this could explain their bloodshot eyes.
- I spend a lot of money on food; last month, I went out to eat 36 times.
- I spend a lot of money on food: last month, I went out to eat 36 times.
The phrase following a semicolon or colon should begin with a lowercase letter, unless it begins with a proper noun. In the case of a colon, use an uppercase letter if the phrase constitutes a complete sentence on its own.
Try to limit your use of colons and semicolons. Separate sentences with a period if possible.
To introduce a list or series:
A colon is generally used before a list or series.
- The Triangle Area consists of three cities: Raleigh, Durham, and Chapel Hill.
Do not use a colon if the list is a complement or object of an element in the sentence.
- Before going on vacation, be sure to (1) set the alarm, (2) cancel the newspaper, and (3) ask a neighbor to collect your mail.
- The colors I hate most are:
- green
- orange
- pink
- magenta
Use a colon after "as follows" and "the following" if the related list immediately follows the stem, or introductory sentence.
- The steps for changing directories are as follows:
- Open a terminal
- Type
cd Documents/Books
Use a colon to introduce a bullet list.
- In the Properties dialog box, notice the following entries:
- Connection name
- Count
- Confirm starting connection
- Confirm stopping connection
- Cost per
Use a semicolon to separate items in a series if the items contain commas.
- Everyday I have coffee, toast, and fruit for breakfast; a salad for lunch; and a peanut butter sandwich, cookies, ice cream, and chocolate cake for dinner.
Use a semicolon before a conjunctive adverb, such as however, therefore, otherwise, namely, for example, and so on.
- I think; therefore, I am.
2.8.2. Commas
In compound sentences:
Use a comma to join clauses in a compound sentence, unless the clauses are short and have a similar theme.
- I spent five hours working on this document, but I lost it when my computer crashed.
- Do you want to go the mall and the grocery store with me, or are you going to watch football instead?
- You play and I'll sing.
A comma can be omitted from a sentence with several clauses, but only when there is little chance that the sentence could be misread without it.
- We played football all afternoon and were completely exhausted but we still stayed up watching movies all night.
That sentence is acceptable, but adding a comma before "...but we still stayed up..." would provide a pause and avoid the chance of having it read like a run-on sentence.
In a compound sentence that contains several short independent clauses, separate the clauses with commas and use a comma before the conjunction.
- You need to go to the grocery store for milk, drop off my dry cleaning, and pick up your little sister from soccer practice.
In adverbial clauses and phrases:
If a dependent clause is restrictive (omission affects the meaning of the main clause), do not set it off with commas. If it is nonrestrictive (omission does not affect the main clause), set it off with commas:
- I'll go to lunch with you if we can get pizza.
- I don't want to go out for pizza, because I had pizza yesterday.
If a dependent clause comes before the main clause, use a comma whether the clause is restrictive or not.
- If we get pizza, I'll go to lunch with you.
- When I heard the voice on the other end of the line, I was quite surprised.
In adjectival clauses or phrases:
An adjectival clause that can be dropped without changing the meaning of the sentence is set off with commas.
- The application, which comes with excellent documentation, is used by many graphic artists.
An adjectival clause that cannot be dropped without changing the meaning of the sentence is not set off with commas:
- The plan that matters most to us will be easy to implement.
With coordinate adjectives:
Separate coordinate adjectives (two or more adjectives modifying the same noun) with commas.
- My dog is loyal, obedient, and affectionate.
- It was a long, boring meeting.
With series and lists:
Separate elements in a series of three or more with commas, including a comma before the conjunction if one is used.
- Today I am wearing socks, shoes, pants, and a shirt.
2.8.3. Parentheses
Parentheses are similar to commas in that they set off information that further explains or enhances a statement. Information that is very closely related to the statement should be set off with commas; information that is more incidental should be set off with parentheses.
- I tried to get to the elevator before the door shut, but I was too slow.
- Most of my favorite authors (Shakespeare, Dickens, Woolf) are dead.
Expressions beginning with i.e., e.g., that is and so on can be set off with parentheses if they cause a major break in the sentence. If the break is minor, use commas.
- He interviewed the biggest stars of the day, namely, Madonna, Johnny Cash, and Jack Nicholson.
- Classic works of literature (e.g., Dickens, Shakespeare, the Brontes) lined the shelves.
If the contents of the parentheses include at least one complete sentence, the period goes inside the parentheses. If not, the period goes outside.
2.8.4. Quotation Marks
Commas and periods go inside quotation marks.
Question marks, exclamation points, dashes, and semicolons go inside the quotation marks if they are part of the quote; if not, they go outside.
Do not put quotation marks around cliches or slang terms (in fact, avoid using cliches and slang as it makes the translation of content more difficult).
A word or words being introduced to readers should not be placed in quotation marks. In DocBook, use the <firstterm> element for first reference. If you are writing outside of the SGML tagging environment, use quotation marks for first references. Subsequent references do not need quotation marks or the <firstterm> element.
2.8.5. Apostrophes
Plural nouns not ending in s should add an 's (for example, the alumni's contribution).
Plural nouns ending in s only need an apostrophe (for example, the horses' food).
Singular common nouns ending in s should add an 's unless the next word begins with an s (for example, the witness's answer or the witness' story).
Singular proper names ending in s only need an apostrophe (for example, Dickens' novels).
2.9. Hyphenation
There are no hard and fast rules for hyphenation. In general, do not hyphenate unless required for clarity, or our other references declare that hyphens are required. The following is general guidance; if you are unsure about whether or not to hyphenate, ask your peers.
Hyphenate for Clarity
Hyphenate when needed for clarity. Words that begin with prefixes are usually not hyphenated. Prefixes can include "multi," "non," "sub," "co," "semi," "pre," "re," and so on. The same applies to suffixes; for example, "less" as a suffix does not require hyphenation.
Note
Hyphenate Complex Adjectives
Hyphenate complex adjectives (compound modifiers). This is when two adjectives work together to modify an object. The hyphen is used when the first adjective modifies the second adjective. For example, cloud-based solutions, right-side paralysis, system-wide menu.
Note
Do not hyphenate "open source," even when used as a complex adjective.
Do not hyphenate a compound that includes an adverb ending in -ly, whether it comes before or after the noun. This is described in Chicago Manual of Style 7.82.
Hyphenate Consecutive Vowel Sounds
Hyphenate words where the prefix ends in a vowel and the word that follows begins with the same vowel. For example, semi-independent, pre-emptive.
Note
Exceptions to this rule include cooperate and coordinate.
Hyphenate Mixed Capitalization
Hyphenate when the word that follows a prefix is capitalized. For example, un-American, non-British.
Hyphenate Double Prefixes
Hyphenate when the word has double prefixes. For example, sub-subparagraph, re-sublet.
2.10. Gender References
Do not use gender-specific pronouns in documentation. It is far less awkward to read a sentence that uses "they" and "their" rather than "he/she" and "his/hers." In most cases, use "you" when giving instructions, and "the user," "new users," and so on in more general explanations. Do not use "one" in place of "you" when writing technical documentation. Using "one" is far too formal.
2.11. Tense
Avoid future tense (or using the term "will") whenever possible. For example, future tense ("The screen will display...") does not read as well as the present tense ("The screen displays..."). Remember, the users you are writing for most often refer to the documentation while they are using the system, not after or in advance of using the system.
Use simple present tense as much as possible. It avoids problems with consequences and time related communications, and is the easiest tense for translation.

3.1. Overall Book Design
This section describes a general approach to the overall layout and design of technical documentation. This design was developed specifically for technical documentation and may not suit content produced by other groups.
This section covers the following topics:
- Titles and subtitles
- Prefaces
- Abstracts
- Introductions
- Unused heading titles
3.1.1. Titles and Subtitles
The title should be a combination of the complete product name, its version, and the name of the book. For example, "Red Hat Satellite 5.6 Installation Guide", or "Red Hat Enterprise Linux 6 Deployment Guide".
The subtitle should be a single, succinct phrase that describes the intent of the book; an abstract of the abstract. For example, "Installing Red Hat Enterprise Linux 6 for all architectures".
3.1.2. Prefaces
The brands that form part of Publican contain a preface as part of the common content. Whether your publication is for external Red Hat customers, JBoss customers, internal customers, or whomever, the brand you choose should provide a suitable preface. Try to use the standard preface to help maintain consistency, reduce overhead and maintenance, and also to reduce translation costs. If you feel that the preface fails to meet your needs, consider whether or not you are using the correct brand, or if the brand itself requires an update.
3.1.3. Abstracts
Abstracts for Red Hat technical documentation typically fall under the heading of a "descriptive abstract." From Wikipedia, "The descriptive abstract, also known as the limited abstract or the indicative abstract, provides a description of what the paper covers without delving into its substance. A descriptive abstract is akin to a table of contents in paragraph form."
[2]
A suitable abstract covers the high-level topics of the book, and is probably a good place to mention the audience. It should cover the following basics:
- What: What is the purpose of the book or document? A brief summary, for example, "The Red Hat Satellite 5.6 API Guide is a full reference for Satellite's XMRPC API."
- How: How does the book convey its content? That is, is it task-based? Example-driven? A reference guide? For example, "The guide explains each API method and demonstrates examples of data models for input and output."
- Why (and possibly Who): A basic rationale for why this book exists, and its audience (and elaborate on the target audience inside the book). For example, "This provides a basis for administrators and developers to write custom scripts and integrate Red Hat Satellite with third-party applications."
Drawing these basics together might produce the following example abstract:
"The Red Hat Satellite 5.6 API Guide is a full reference for Satellite's XMRPC API. The guide explains each API method and demonstrates examples of data models for input and output. This provides a basis for administrators and developers to write custom scripts and integrate Red Hat Satellite with third-party applications."
Update or modify each component according to the type of book you are writing.
3.1.4. Introductions
The term "introduction" on its own is sufficiently vague, and raises enough questions in translation and with translation memory (TM) tools, that Red Hat technical documentation does not use this term on its own. Instead, use the phrase "Introduction to $productname" near the beginning of the book to introduce the reader to the product. Do not use "Introduction" to introduce the book; that is the task of the Abstract. A further benefit of this usage is that the same introduction can be used across various books to introduce the same product.
3.1.5. Unused Heading Titles
This section lists various heading titles that have been used in Red Hat technical documentation, but should be avoided except in specific circumstances.
Overview
Do not use "overview" as a title. No justification was found for using this as a title; anywhere that it might be considered is already covered by either better or more common titles.
About
Do not use "about" or "about $topic" as a title. The same reasoning applies here as to "overview."
Chapter and Section Introductions
Do not create separate introductions for chapters and sections. Use any material that would constitute an introductory section to form body text following the chapter or section title.
3.2. Heading Styles
This section covers various aspects of heading styles and design. If your company or organization has specific requirements in this regard, follow those requirements first.
Capitalization
The standard for all Red Hat technical documentation is title case for all headings and titles. Diagram labels, table headings, procedure, and formal paragraph titles all fall under this heading, and consequently, standard title case capitalization rules apply. The currently accepted reference for determining title case is https://titlecase.com/titlecase.
Use sentence case for table column headers. These are not classified as titles.
Marketing and Brand Capitalization Guide
The Red Hat Marketing and Brand groups use sentence case for most titles and headings, with some exceptions, for example, when referencing an externally produced resource's title.
Punctuation
Be frugal with punctuation. In most cases, avoid semicolons, colons, dashes, and similar punctuation unless part of the actual subject, or a proper name. Do not use terminating periods.
Avoid Imperative Form
Use the gerund form (noun form of verb) for titles, not the imperative form.
See The IBM Style Guide for more information.
Important
Gerunds should be avoided elsewhere. Refer to Section 2.4, “Sentence Structure”.
File Names, Commands, and Related Terms
When creating chapter and section titles, do not include file, command, or similar names, and do not include DocBook elements. Instead, focus on the task at hand and introduce the required file and command names in the text. Including such objects in titles is generally considered poor technical writing practice. Depending on how your documentation is built and delivered, including these object types can result in unpredictable results and even cause failed builds.
3.3. Documenting Fonts
The preferred way to refer to each type of postscript font is "PostScript Type x," substituting "x" with either 1, 2, or 3, if the problem is specific to a particular type.
3.4. Documenting the User Interface
In all cases, see The IBM Style Guide for initial guidance. The following sections highlight exceptions or cases that might otherwise cause confusion.
3.4.1. GUI Elements and Punctuation
Do not include punctuation that appears on GUI elements, unless omission of that punctuation might lead to confusion.
For example, for a button labeled , do not include the ellipsis in the documentation.
See the Computer Interfaces chapter in The IBM Style Guide for more information.
3.4.1.1. Navigating Through Multiple GUI Options
Use "Navigate to" when moving through multiple GUI options because it covers all cases where you might have to click, point to, select, or otherwise make a series of selections to initiate an action.
From example, "From the OpenShift web console, navigate to Monitoring → Alerting."
3.4.2. Starting Applications from the Red Hat Enterprise Linux Desktop
Red Hat Enterprise Linux 7 introduces a new approach to starting applications from the desktop. In an effort to maintain consistency and to make translation easier, Red Hat documentation assumes the customer is using GNOME Classic, the default user interface, and prefers a consistent approach to instructing customers how to start applications.
The preferred approach is to use the Super key to enter the Activities Overview, enter the name of the required application, and to press Enter. The Super key appears in a variety of guises, depending on the keyboard and other hardware, but often as either the Windows or Command key, and typically to the left of the Spacebar. For example:
Example 3.1. Preferred Approach to Starting Applications from the Desktop
To start
gedit, press the Super key to enter the Activities Overview, type gedit, and then press Enter.
3.4.3. Documenting Command Terminology and Syntax
Sufficient variation exists in the terminology used to describe commands, options, arguments, and so on that only general advice is provided here.
When referring to the command line as specified by Bash and POSIX, follow the terminology that the software uses. Never use "flag" when referring to command-line options in POSIX, even though Microsoft often uses the term "flag" when referring to single-character options in Microsoft Windows.
The following extract from
info libc is of particular interest here:
"POSIX recommends these conventions for command line arguments. [...] Arguments are options if they begin with a hyphen delimiter (‘-’). Multiple options may follow a hyphen delimiter in a single token if the options do not take arguments. Thus, ‘-abc’ is equivalent to ‘-a -b -c’. [...] Certain options require an argument. For example, the ‘-o’ option of the ‘ld’ command requires an argument—an output file name." and so on.Seeinfo libc argument syntaxfor the full discussion.
See
info bash and the Computer Interfaces chapter of The IBM Style Guide for further guidance.
The following examples are intended to highlight correct usage.
Example 3.2. Cloning a Git Repository
$ git clone [username@]hostname:/repository_filename [directory]
In Example 3.2, “Cloning a Git Repository” the entire command consists of the following components:
-
The prompt (
$) - Indicates that a normal user can run the command, as compared to the
rootuser, indicated by the number sign (#). -
The command (
git clone) - The actual command to run, without any optional or replaceable values. This must be typed as is.
- Source options [username@]hostname:/repository_filename)
- The optional user name, indicated by brackets ([]), followed by the host name and path to the repository. All aspects of this component must be replaced with valid values.
- Target options [directory]
- The optional directory into which the repository will be cloned. This must be replaced with a valid value, or omitted.
In Example 3.3, “Securely Copying a File Between Hosts” the entire command consists of the following components:
-
The command prompt (
$) - Indicates that a normal user can run the command, as compared to the
rootuser, which is indicated by the number sign (#). -
The command (
scp) - The actual command to run, without any optional or replaceable values. This must be typed as is.
- Source options (filename)
- The file name to copy. This must be replaced with a valid value.
- Target options ([username@]hostname:/directory)
- The optional user name, indicated by brackets ([]), followed by the host name and path to the target directory. All aspects of this component must be replaced with valid values.
Warning
Avoid using the
--force (-f) and --assumeyes (-y) options on most commands, especially when logged in as the root user. This can lead to unintended consequences, such as removing files or directories by mistake or installing packages or other software that may not suit your system. Refer to the following examples:
[root@serverc pam.d]# rm -f system-auth password-auth [root@serverc ~]# yum install -y new-package
In the examples shown above, omit the
-f and -y options, respectively.
In some cases, such as in Ansible Playbooks or other automation scripts, it may be necessary to use these options.
3.4.3.1. Documenting Multiple or Long Commands
Sometimes you need to demonstrate how to use very long commands that extend over two or more lines, or include several commands in a single example. If the commands are relatively short and straightforward, include the commands on consecutive lines:
If the commands are long, complex, or wrap over multiple lines, two design options are available.
- Use line continuation characters and the associated PS2 prompts. If you are documenting commands on a different operating system, update the prompts and line continuation characters to suit.
- Use neither line continuation characters nor the associated PS2 prompts.
Important
Do not mix these two styles. Maintain the same style throughout your document or book.
You can also indent the second and subsequent lines of such commands to assist in clarity and readability if required. You can use this option for either of the two designs mentioned above.
Example 3.5. Wrapping Long Commands with Continuation Characters
This example uses both continuation characters and PS2 prompts. These indicators are always used together.
# tar --selinux -czvf config_files.tar.gz /etc/katello \ > /etc/elasticsearch /etc/candlepin /etc/pulp /etc/gofer \ > /etc/grinder /etc/pki/katello /etc/pki/pulp /etc/qpidd.conf \ > /etc/sysconfig/katello /etc/sysconfig/elasticsearch \ > /root/ssl–build /var/www/html/pub/* /var/lib/katello
Example 3.6. Wrapping Long Commands Without Continuation Characters
This example uses neither continuation characters nor PS2 prompts, but it does demonstrate how to use line indentation to help clarify long commands.
# cd /var/lib/katello # myCommand --option funky --color=true --config_file=<replaceable>/home/user/config.conf</replaceable> --output_file=<replaceable>/home/user/output.txt</replaceable>
3.4.3.2. Referring to Replaceable Paths
To refer to a path that users need to replace with something specific to their system, use <replaceable> tags, the correct syntax for the system and object in question, and an indicative name. Use a leading slash if the absolute path is required.
Example 3.7. Referring to Replaceable Paths on Linux Systems
"Mount the ISO file in <filename><replaceable>/path/to/iso/file</replaceable></filename>."
Remember to use the syntax appropriate to the system that you are documenting or describing.
Example 3.8. Referring to Replaceable Paths on Microsoft Windows Systems
"Mount the ISO file in <filename><replaceable>C:\path\to\iso\file</replaceable></filename>."
If you are referring to a different object class or type with different delimiters, use the appropriate delimiters. For example:
A PATH variable for Bash might appear as <replaceable>/usr/bin:/usr/local/bin</replaceable>.
A package path in Lua might appear as <replaceable>local.share.lua</replaceable>.
3.4.4. Describing How to View and Edit Files
To describe how to view and edit files, such as configuration files, scripts, and so on, do not include editor names as part of the guidance, unless the topic is about a specific editor, or is otherwise necessary to achieve a desired result.
For example, do not refer to
cat or vi if you need to tell readers to "View the my-script file." If you need to tell readers to edit a file and add or remove content, write "Edit the my-script file and add the following content:" and then include the required content in a <screen> block. Use <code> tags to highlight the text that needs to be changed. Include some surrounding text in the file for context. Do not use line numbers as a reference point because they can change.
If the file that you need to edit is empty or does not exist, do not use <code> tags to highlight any content that needs to be added.
You can also use
here documents to describe how to create a file with required content. The syntax of here documents varies by system, shell, language, and so on, but a simple example is shown below. This example creates the my-script file in the current directory, using the example content.
$ cat << EOF > my-script > # The first line of text > # The second line > # Start adding variables after this line > EOF
In some cases it is necessary to indicate which tool to use to view a file. This is especially true of log files and other very long files. In these cases, suggest a viewer based on the operating system or environment in which you are working, such as
tail, head, less, or journalctl.
3.4.5. Using Host and User Names Correctly
Many examples in Red Hat documentation require the use of user names, host names, IP addresses, and similar information. In an effort to reduce security risks, to minimize translation overhead, and to maintain consistency, Red Hat recommends the following.
Note
All names are lowercase. Do not use white space in any part of the name.
- Use RFC 2606 to determine suitable domain names. For documentation and example purposes, this is typically
example.com,example.net,example.org, andexample.edu.Important
Do not use valid, public IP addresses in any examples. - As much as possible, use
user,username,root,admin, or similar names to identify classes of users.Use these generic names when you refer to users outside of a case study. This helps students identify which part of a command can and should be replaced by establishing a consistent format for names of users and system items. For example:[root@fedora ~]#setfacl -m u:user1:rw /project/file1The following list provides further alternatives:operator1tooperator9developer1todeveloper9architect1toarchitect9
3.4.5.1. Using Extended User and Group Names
Sometimes, the recommended list of user and group names is too restrictive for the scope of a book or article. In such cases, the following extended model is acceptable.
Using Realistic User Names
When you are writing a detailed case study, such as training exercises, reviews, and similar material, use realistic names. These names should not be real people. In other words, do not use the name of an employee, a well-known person, or your neighbor.
For example, you are the system administrator at Global Banking and you have been asked to set up permissions to the accounting directory for the following users: John Doe, Sunni Koning, Huong Sabo, and Jerlene Paluch. John is a department manager and needs to be able to read from the accounting directory, Sunni is the lead accountant and needs both read and write access.
- In examples or scenarios, you can use a person's name and then use a gender-specific pronoun to refer to that name. Vary the use of proper names in documentation. Use names that represent various ethnic backgrounds, genders, and locations.
- Do not use copyrighted fictional characters in examples, and do not use real people.
- Include a diverse set of names in your examples to reflect the diversity of the real world. For example, use male, female, and culturally diverse names that suggest a variety of backgrounds in examples to avoid implying that only certain groups have specific skills.
Sourcing Realistic Names
You can use any of the following name generators to create realistic names for users:
Group Names
Use any lowercase name that is a logical extension of the accepted user names, without the numerical suffix. For example, architects, developers, operators.
3.5. Documenting Currencies
Use local currency symbols wherever possible. If symbol clash occurs (USD vs AUD, for example), disambiguate with the 2-character country code. For example, US$, AU$.
Important
Do not provide currency conversions.
3.6. Using Abbreviations, Acronyms, and Initialisms Correctly
This section describes how to use abbreviations, acronyms, and initialisms correctly in Red Hat documentation.
Abbreviations
An abbreviation is a shortened form of a word or phrase. For example, Pty. and Inc. are abbreviations for "proprietary" and "incorporated," respectively. Read them as the word for which they are an abbreviation.
Acronyms
What are acronyms anyway? They are similar to abbreviations and initialisms but they are pronounced as an actual word. For example, COBOL is the acronym for Common Business-oriented Language, and POP is the acronym for Post Office Protocol.
Bear pronunciation in mind when using articles. For example, use "an RTS (real-time strategy)," because RTS is an initialism and you pronounce the first character as an "R" (är). Conversely, use "a RAM upgrade," because RAM is an acronym and you pronounce it as a word (răm).
Be sure to use correct capitalization for acronyms. Not all acronyms are capitalized (for example, "spool"); see The IBM Style Guide or another suitable reference if you are unsure.
Initialisms
An initialism is an abbreviation that consists of the first letters of words in a phrase, syllables, or some combination thereof. Each character is pronounced separately. For example, FTP is an initialism for File Transfer Protocol.
Bear pronunciation in mind when using articles. See acronyms for more information.
3.7. Using Company, Product, and Brand Names Correctly
A number of restrictions apply to using company, product, and brand names in Red Hat documentation. Refer to internal sources for further conditions that might apply to your own products.
Note
In the following sections, "first use" refers to the first use of a name in body text. Titles, banners, and similar objects are not classified as "first use."
- Restrictions apply to abbreviating Red Hat product or solution names in public-facing documents. Always use the full name on first use. For some products, for example Red Hat OpenShift Container Platform, you can omit "Red Hat" after the first use.
- Further restrictions apply to using acronyms and initialisms. In this same example, and only in technical documentation, "RHOCP" is acceptable after the first use of the full product name.
- Do not include "Inc." when referring to Red Hat except in legal documents.
- Use non-breaking spaces to avoid breaking the company name over multiple lines. This also applies to product names and their versions. For example, use a non-breaking space between "Red" and "Hat," and also between "Enterprise," "Linux," and the version number.If you are working with images or other objects where space is especially tight, this rule is more flexible, but "Red Hat" should never be broken over two lines.
- Do not use non-breaking spaces between "Red Hat" and any product name. Consider the following examples:
- Standardize on Red Hat Enterprise Linux.
- The latest version is Red Hat Enterprise Linux 7.0
- Do not use non-breaking spaces between extended components of Red Hat product names. For example, "Red Hat Enterprise Linux OpenStack Platform" does not require a non-breaking space between "Linux" and "OpenStack" nor between "OpenStack" and "Platform."
- Do not use non-breaking spaces with other companies' product names.
- Do not use articles in front of product names. For example, do not write "the JBoss Enterprise Application Platform was..."
Note
In this case, "Platform" is part of the product name. In other cases, words like "platform," "manager," and so on may not be part of the product name, in which case an article is acceptable, if not necessary.
3.8. Using Version Numbers Correctly
The preferred format for product names includes only the major version number. For example:
- Red Hat Enterprise Linux 7
- JBoss Enterprise Application Platform 3
When writing about a product line, product release, or product family, use major version numbers. This includes all the releases (past, present, and future) of that major version.
Only use minor version numbers when you are referring to a specific minor release, or to a feature that is specific to that minor release. For example:
- Red Hat Enterprise Linux 5.2 was released on October 12, 2010.
- <Application name> was first included in JBoss Enterprise Application Platform 3.2.
In most cases, major changes take place in major version releases, and are carried through any minor updates to that release. If you are referring to a major change, or to the first appearance of a new technology, it is therefore most accurate to refer to the major release.
Avoid using the "dot-oh" release number. For example, do not use Red Hat Enterprise Linux 6.0. Use instead Red Hat Enterprise Linux 6.
Important
This rule only applies to Red Hat products. Refer to other companies' products and use their version numbers as they use them.
3.9. Using Admonitions
To call attention to a statement, use an admonition. Red Hat technical documentation currently uses
Note, Important, and Warning admonitions.
Admonitions automatically include a suitable title according to the type of admonition. Do not use a phrase or anything else for the title. Keep the following in mind if using admonitions:
- Keep the statements as brief and to the point as possible.
- Use admonitions sparingly so that they do not lose their effectiveness.
- Use a
Noteadmonition to bring additional information to the user's attention. - Use an
Importantadmonition to show the user a piece of information that should not be overlooked. While this information may not change anything the user is doing, it should show the user that this piece of information could be vital. - Use a
Warningadmonition to alert the reader that the current setup will change or be altered, such as files being removed, and not to perform the operation unless fully aware of the consequences.
3.10. Making Recommendations
When making a recommendation, the preferred verbiage is "Red Hat recommends..." instead of the common but indirect "It is recommended...". Recommendations can include best practices, recommended practices, and product-specific suggestions. Refer to Section 4.1, “Avoiding Misleading or Confusing Language” for information on using the terms "best practices" and "recommended practices" in Red Hat documentation.
Example 3.9. (incorrect)
"Although the attack surface is reduced to the same-project traffic, it is recommended to create multiple service accounts within a project."
"It is recommended to generate a service account for each microservice in your project."
Example 3.10. (correct)
"Although the attack surface is reduced to the same-project traffic, Red Hat recommends creating multiple service accounts within a project."
"Red Hat recommends that you generate a service account for each microservice in your project."
3.11. Citing Other Works
Referencing Other Books
When referencing another book, either internal or external to Red Hat, use the following format:
In XML:
<citetitle>Book Title</citetitle> by <author><firstname>First name</firstname><surname>Surname</surname></author>; Publisher.
For example, Maximum RPM by
; Red Hat Press.
Referencing Other Internet Sites
When referencing another internet site, use the following guidelines:
- Do not link words within the body text. That is, do not use structures such as "Go here for more information," where "here" is a link.
- Short URLs, such as http://partner.redhat.com are OK to use in body text at your discretion.
- If the URL is excessively long, or complex, create a link using the title of the destination as a label, and put the actual URL in a footnote. For example: See the Classification of Species [4] page for more information.
3.12. Citing Other Authors
DocBook provides the <blockquote> and <attribution> tags for this purpose, but how they should be rendered is currently being discussed. For example:
Why use two words when one will do?
| ||
| --Thomas Jefferson | ||
Chapter 4. Avoiding Jargon, Slang, Metaphors, and Misleading Language
Red Hat produces documentation for a global audience, and in many cases this documentation is translated into many languages. To reach the widest possible audience, and to make the task of translation as straightforward as possible, avoid slang and other culture-specific terminology. This section attempts to identify commonly used slang terms and phraseology, and to provide alternatives.
If you find slang terms or other difficult-to-understand passages in our documentation, use this page to search for alternatives.
4.1. Avoiding Misleading or Confusing Language
Some terms, phrases, and general language can be confusing if you are not a native speaker or if the phraseology has regional significance. Sometimes spelling changes are introduced over time and regions, based purely on differences in pronunciation. Some phrases can carry hidden or unintentional meanings. This section attempts to introduce a few examples.
- best practices
- This is a commonly understood phrase, and despite some concerns about using superlatives without statistics to back them up, Red Hat does not actively discourage its use. It is also a more common search term than most alternatives. If you are in any doubt, the preferred alternative is "recommended practices."See the section Section 3.10, “Making Recommendations” for additional information about recommendations in Red Hat documentation.
- first come, first served
- Indicates that customers will be attended to in the order that they arrive. The phrase abbreviates the sentence "The first to come is the first to be served," so use "served" instead of "serve" to keep the verb function the same. This phrase is an idiom, so avoid using it when content will be translated. When you use this phrase as an adjective, it is hyphenated as follows: Admittance is on a first-come, first-served basis.
4.2. Identifying and Avoiding Slang
Examples of slang terms:
- administrivia
- Not a word. Do not use.
- anything you/they like
- This is probably readily understood but should not appear in Red Hat documentation.
- "They can also use the slapi_register_plugin() call to register any kind of plug-in they like."Rephrase to something more suitable, such as "...to register any other kind of plug-in."
- ask (as a noun), make the ask
- Ask is a verb. Do not use it as a noun.
- at this point in time
- Do not use. In most cases, use "now." In some cases it is acceptable to use "at this point," for example, when you have reached a specific point in a procedure.
- automagic
- Also, automagical. Both terms are slang. Do not use.
- best-of-breed
- Jargon. Say exactly what you mean, for example, "the best product in its class" or "the best product of its type." Other alternatives include best, foremost, most advanced, optimum. The category is usually implied. Be wary of using superlatives without data to back up any claims.
- bleeding edge
- Do not use.
- bottom line
- Traditionally used in financial contexts; avoid overuse.
- bucketize
- Not a word. Try "categorize" or "organize into logical groups."
- center of competency
- Do not use.
- check this site
- Understood to mean "have a look at this website." The preferred phraseology is "See www.somewhere.com for more information." It is better to avoid "check" because it has so many meanings.
- coopetition
- Not a word. Do not use.
- core competency
- Jargon, cold and impersonal. Better choices include "specialization," "skill," "strength," "expertise," etc. The De-Jargonator says: "'Competent' means 'adequate but not exceptional.' Why would you describe what you do best as 'competence'? Try instead: What your organization does best; competitive advantage; special or unique expertise or ability; specialty."
- eat your own dogfood
- Developer-speak. It means to use your own products. You can get a detailed description at http://en.wikipedia.org/wiki/Eat_one%27s_own_dog_food.
- data point
- Do not use.
- dig deeper, delve deeper
- "Visit the following web link to dig deeper into [subject]..." Using "dig deeper" may translate awkwardly. Consider rewording: "For detailed information regarding [subject], see [link]."
- double-edged sword, double-bladed sword
- If something is described as a double-edged sword, it indicates that it has two opposing behaviors or consequences. Instead, state that it can have unexpected consequences, or that the positive result might be offset by the negative result.
- enterprise-ready
- Although we used to use this term to emphasize our products' enterprise readiness, it is not as necessary now, especially when talking about a product with "Enterprise" in its name, unless you're calling this out as a key selling point.
- exceed your expectations
- Vague. Clarify with specifics, for example, "The movie made more money on the opening weekend than anyone expected." instead of "The movie exceeded our expectations."
- fib
- A fib is a "small lie," also known as a "white lie." This appeared in one of the GLS books: "this command tells fibs." Use something like "The output of this command can be misleading."
- flying by the seat of your pants
- Generally understood to mean "reacting to events as they occur." Difficult to offer alternatives without context.
- frame it up
- Do not use.
- frown upon
- "To frown upon" means to hold in low regard, not to approve of, etc. This appeared in the Seam guide: "...we generally frown on the use of session context...". This translates to (and should have been written as) "...the use of session context is not recommended..." (or words to that effect).
- fuzzy (search)
- Even though "fuzzy" is slang, it is common when referring to searches, especially in databases. This example came from the Directory Server documentation:
- In Directory Server, if you do a fuzzy search for "Smith" you will probably also get "Smyth," because it sounds the same.
The use of "fuzzy" is valid in this context.Note the difference between this and "wildcard" searches: "Sm?th" could return "Smith," "Smyth," "Smeth," or even "Smrth."Do not use "fuzzy" to describe something that is not clear, such as an image, a concept, an idea, and so on. For example, "He was a bit fuzzy on the details" is not valid. - going-forward basis
- Jargon. Say "from now on," "in the future," or something similar.
- happy path
- Do not use. Often understood to mean "a path or method of least resistance" or "the preferred way to solve the current issue", this is very localized slang and could easily be misunderstood. It could also produce problems for translation.
- harness the power
- Do not use.
- have a crack at/jump right in
- Have a crack at and jump right in are closely related in meaning as they imply to "get started or give it a try." Alternatives to these are "start," "try," and "begin," and will depend on the context of what is being discussed.
- if you want, if you wish
- Do not use. For example, instead of saying "If you want to perform an action,..." say "To perform an action,..."
- in concert with
- Do not use. Instead, say "with." For example, change "Use gcov in concert with GCC to analyze..." to "Use gcov with GNU CC to analyze..."
- improve, enhance
- Vague. Try to be more specific.
- in a pinch
- Under a tight schedule, hard pressed to achieve something.
- infomediary
- Not a word. Do not use.
- is designed to
- Avoid this and similar phrases when describing products and services. Instead, state what the product does.
- Incorrect: SSH is designed to work with almost any kind of public key algorithm or encoding format.
- Correct: SSH works with almost any kind of public key algorithm or encoding format.
- kettle of fish
- Commonly used in the expression "a different kettle of fish," meaning "that's a different matter (altogether)." Depending on the context, try to use "topic," "subject," "matter," or something similar.
- leverage
- Avoid. Alternatives include "use" and "take advantage of".
- lights on, lights-on
- Avoid using this term, because 1) it is jargon, 2) not everyone knows what it means, and 3) the meaning could be lost or confused in translation to other languages.Typically used to mean maintaining the status quo or just doing what is required to keep things up and running (versus being proactive and innovative). For example, "A cloud can deliver strategic advantages to the business by redirecting resources from lights-on to innovation."
- low-hanging fruit
- Metaphor. Do not use.
- marketecture
- Not a word. Do not use.
- meet your needs
- Vague. Try to be more specific, for example, "lower your middleware costs."
- mission-critical
- Overused and jargony. Unless the topic is actually critical to a mission, use a factual term or phrase, for example, "Make sure you have the applications you need to help your customers." vs. "Make sure you have the mission-critical applications your customers demand."
- net-net
- Jargon. Use "in summary," "the end result," or something similar.
- niche focus
- Do not use.
- over the wire
- Commonly used in expressions such as "password information is sent in plain text over the wire," meaning "sent unencrypted through the transmission medium" (whether it is a wired or wireless network, the internet, or whatever). The phrase is probably not required at all. "Sent/transmitted in plain text" is fine.
- pain in the backside
- Nobody should ever write this or anything like it in any Red Hat documentation. Most people should know what it means. Use "problematic," "difficult," or something similar.
- paradigm
- Avoid. Use "model," "standard," or something similar.
- performant
- In the technical industry context, it means "performs as expected" or "well-performing." It is not necessarily a word everyone knows (and technically, it means "a performer," as in a play, according to most dictionaries), so use an alternative if possible.
- physicalize
- Not a word. Do not use.
- piggyback
- Slang. Do not use.
- pre-baked
- Means "prepared beforehand." Choose a suitable alternative, such as "preconfigured," depending on the context.
- productize
- Not a word. Find another way to say "modify something to become suitable as a commercial product." [wiktionary]
- ready to rumble
- "Let's get ready to rumble!" is a trademarked catchphrase used to introduce televised boxing or wrestling events. In US English slang, being "ready to rumble" means you are "ready to go ahead" or "ready to start."
- rest on your laurels
- Do not use.
- right before doing something
- Preferred phrase would be "immediately before doing something." Otherwise, write around the phrase.
- root your server in the /serverRoot directory
- This is not very elegant. Be aware of the multiple meanings of words. Try something like "Use the /serverRoot directory as the root directory for your server." This example came from the Directory Server documentation, but it could apply to Web Servers or any other type of server.
- shoot yourself in the foot
- To "shoot yourself in the foot" indicates that you have done something to harm your own cause, or acting against your own best interests. Remove the sentence - it should be self-evident from the surrounding information. (Found this statement alongside the "double-edged sword" comment with an added note about "preserving all your toes.")
- shy of
- Apart from the "normal" meaning of shy, it is also found in such phrases as "he was just shy of the mark," meaning that he didn't quite succeed. Also, to be "a few items shy of what's required" means to have less than the minimum number required. Avoid this terminology and use more easily understood terms; it will help our translators and also those reading our English documentation who are unfamiliar with such slang.
- silo, siloed
- Useful in farming, but in business it is jargon. Use "stand-alone," "confined," "separated," "segregated," or something similar.
- solutioning
- Not a word. Lazy version of "creating a solution."
- solutions-based
- Do not use.
- solution stack
- Do not use.
- stovepipe
- Jargon. In business, related to lack of cross-organizational communication, similar to "silo."
- synergistic, synergy
- Jargon. Use "cooperative," "working together," "collaborative," "harmonious," or something similar.
- synergical connectivity
- Seriously?
- to think outside the box
- 1990 called and wants its jargon back. How about "(think) creatively" or "(think) unconventionally"?
- tunnel vision
- Do not use.
- under the covers
- This refers to something being out of plain sight or not immediately obvious. For example, you might only see the results of some action or command, but what happens "under the covers" is what is going on in the background, that you can't see or are not aware of, to make that action of command possible.
- value-added
- Jargon. Say "added value" or "valuable." Or be more specific, for example, "adds value by improving productivity."
- very
- Use with caution. For example, there is little value in saying "very cost-effective" vs. "cost-effective."
- virtual elephants
- This refers to a group of blind-folded people all touching different parts of an elephant and trying to describe what it is. Nobody sees the "big picture." Curiously, it appeared in an STC article about working in global and virtual teams and using effective communication. It falls into the same category as "skeletons in the closet," "dark horse," "black sheep," and so on. Use descriptions and adjectives that are not specific to a particular culture or locale. See http://en.wikipedia.org/wiki/Blind_Men-anElephant for more information.
4.3. Neologisms (Invented Words)
The English language is full of these. Some of them are useful, some of them are less so, others are just painful, difficult to translate, and should be avoided. Many of them are the result of creating nouns from verbs, verbs from nouns, and adjectives from just about anything. Unless a particular word has been in use for some time and has been generally accepted into common English, try to avoid these neologisms. If necessary, reword or restructure your sentences.
Examples
- "This feature allows synchronization of adds, deletes, and changes ..."
- This sentence has converted three verbs to nouns. A better structure might be, "This feature allows the synchronization of add, delete, and change operations..."
4.4. Anthropomorphism
Anthropomorphism is applying human qualities to non-human things or animals. Avoid this in your writing.
Examples
- The computer will think for a brief period.
- Computers do not actually think but they might take a while to "process" commands.
- The Proxy Server is talking to either RHN Hosted or a Satellite Server.
- It is quite common to say "talk to" in this context, but "communicate with," "connected to," "registered with," or something similar would be better.
Chapter 5. Writing Clearly and Succinctly
This chapter provides guidelines, tips, and techniques to help make your writing easier to read and understand, and also to translate.
5.1. Sentence Structure
This section helps to describe how to construct your content for clarity and readability. A full discussion of this topic is beyond the scope of this guide.
5.1.1. Using and Formatting Lists
Lists appear in a range of formats, such as series, ordered, unordered (itemized), and so on. Avoid using itemized lists to format a single sentence. Some translation tools display list items and the introductory sentence (or sentence stem) as individual sentences for translation. If these are not complete sentences, they can be difficult to translate.
The following general guidelines apply to lists:
- Itemized lists
- These appear as a bulleted list. Use this list type for three or more entries where order is not important, or in a demonstration section when students are encouraged to not perform steps but to watch the instructor instead. Titles are optional.
- Ordered lists
- These appear as a numbered list. Use this list type for multiple entries if you need to refer to one of the entries from elsewhere in your document, or where order is important. For example, if you need to list the order of operations required to prepare for an installation, or list a sequence of events that occurs. Titles are optional.
- Variable lists
- These appear as a list of terms followed by definitions. Use this list type to list and describe a series of terms, such as variables, command options or arguments, and similar items. Titles are optional. (This list is written as a variable list.) A variable list is often preferable to a table, because tables have the additional overhead of calculating column width for every translation. Tables are best reserved for information that relies upon, or benefits greatly from, a grid layout.
- Procedures
- These appear as a list of numbered steps. Procedures always include a title, and are used to list the steps required to achieve a task.
You can nest lists, but try to keep the number of levels to two or fewer. To nest procedures in DocBook, use <substep> elements.
5.1.1.1. Formatting Lists for Readability
It is important to provide sufficient spacing between elements in your documents to facilitate reading and comprehension. You can include a lot of information in a few short paragraphs but readers need to be able to process that information in chunks. The same applies to lists. If you use DocBook to build itemized, ordered, or variable (definition) lists, you can use the
compact or normal attributes to specify the spacing between list items. DocBook uses the normal spacing attribute by default.
Use a list with normal spacing if any list item contains the following:
- Nested lists. Note that nested lists themselves can use the
compactattribute if they fall outside the bounds of these recommendations. - Navigation or similar instructions (such as "Navigate to Menu -> Submenu").
- Multiple paragraphs, or sentences that wrap to two or more lines.
Use a list with compact spacing in all other cases.
Note
The use of all but very simple graphics in lists is strongly discouraged.
The following discussion provides some initial insight into using lists correctly. See The IBM Style Guide for a full discussion.
Table 5.1.
| Example | Improvement |
|---|---|
|
Before you start the installation, make sure you have
to ensure a smooth installation.
|
Before you start the installation, follow these steps to ensure a smooth installation:
|
5.1.2. Noun Stacking
Modifier strings (modifier + noun + noun sentence format), over-modified nouns (or noun stacks), are especially difficult to translate, particularly when several different combinations could make sense.
Table 5.2.
| Example | Improvement |
|---|---|
| Plastic tubing and syringe tips. | Plastic tubing and plastic syringe tips. |
| Set default printer configuration parameters for new users. Enter the maximum length of time that you want to keep the automatic synchronization address list updates in days and press ENTER. | For new users, set the parameters to the default printer configuration. Enter the maximum length of time, in number of days, that you want to keep the address lists updated by automatic synchronization. Then press ENTER. |
5.2. Grammatical Genders
When using ambiguous pronouns such as "they" or "it" it is not always clear what they refer to. For languages that have different genders for nouns, it is important to know exactly what each pronoun refers to. For example, the word "it" can be translated in several different ways and may require other grammatical adjustments.
Further, an initialism such as RPM might refer to the package or the package manager. In German, manager is a masculine noun, and so RPM requires the masculine article "der" when it refers to the RPM Package Manager. Package is a neuter noun, and requires the neuter article "das" when it refers to an RPM package.
Table 5.3.
| Example | Improvement |
|---|---|
| Set the parameter XYZ to 1 in the configuration file /etc/config.conf. It configures the way the Gateway application handles incoming network traffic. | Set the XYZ parameter to 1 in the configuration /etc/config.conf file. This parameter configures how the Gateway application handles incoming network traffic. |
| The RPM is useful. | The RPM package is useful. OR The RPM Package Manager is useful. |
5.3. DocBook Elements
Use the correct DocBook elements to help translators understand the meaning of and to identify translatable and non-translatable terms.
Tagged Terms in Sentences
Many tagged terms are not translatable, and so they should not be used as structural parts of a sentence. Otherwise, translators have to fill in the blanks or tag terms themselves.
Table 5.4.
| Example | Improvement |
|---|---|
In /some/path/, grep for XYZ. | In the /some/path/ directory, use the grep command to search for "XYZ". |
param-2 contains a reference to the hostname return value from instance-2. | The param-2 parameter contains a reference to the hostname return value from your second server instance, instance-2. |
| Troubleshooting Glance. | Troubleshooting the Glance image service. |
| Installing the maven-changelog-plugin. | Installing the maven-changelog-plugin package. |
5.4. Code Blocks
Avoid including commentary within the same box as command input or output. These might be confused with part of the output, and during translation might be accidentally overlooked and left in English.
For example, consider the word "Usage" in the following:
Usage:rhevm-iso-uploader [options] listrhevm-iso-uploader [options] upload [file1] [file2] [file3]
5.5. Entities
An entity is a primitive data type, which associates a string with either a unique alias (such as a user-specified name) or an SGML reserved word (such as #DEFAULT)
[5]. Entities are called by reference, and take the form &name; (both the ampersand and the semicolon are required).
Entities can be helpful in some cases, but they are more of a hindrance when used for terms that need translation. Translators need to compare the string with the built document to determine what the entity stands for. These entities might even be overlooked and not translated at all.
To avoid issues with incorrect or outdated entity values, problems with translation, and so on, only include the entities required to actually build your books. If you use Publican (https://fedorahosted.org/publican/) to create and maintain your documentation, it creates and populates the required entities with default values when you create a book. Required entities vary by brand, but only the following are required for a standard book:
- PRODUCT
- BOOKID
- YEAR
- HOLDER
Do not include entities such as &PRODNAME; or &VERSION; and so on, or things like &BIBLE; to represent "The St. James Bible". To learn more about entities, see the relevant chapter in http://jfearn.fedorapeople.org/en-US/Publican/4.0/html/Users_Guide/index.html
Chapter 6. Using Cross-references Effectively
This section contains suggestions on how to use cross-references in the most effective way. That is, so that it works for the reader, rather than the author. In DocBook XML, cross-references are formatted according to the style sheets; at this point no references are available that describe how they should be formatted in other media. Formatting is not described in this section.
In the days of print-only documentation, cross-references referred readers to additional or related information that existed elsewhere in the physical printed book; on other pages. The readers had to physically turn pages to find the referenced page, so authors, editors, and proofreaders developed a certain caution about scattering cross-references through the text. Despite the ease of use and creation of cross-references and links in online documents today, the author must still do the work for the reader. It is still the author who must do the heavy lifting and arrange the information so that the reader can absorb it in the smoothest possible fashion. Forcing the reader to leap from link to link could indicate that the author is writing for their own ease, and not for the good of the reader.
6.1. The Additional Information Test
Is the cross-reference pointing to vital information or additional information?
A cross-reference should always point to additional information, not core information that the reader needs to perform the task at hand. For example, in a procedure to configure an application, do not merely provide a link to the appendix where the correct naming conventions are described. Give the reader examples and explanations of a valid file name, and at the end of the procedure provide the link to the appendix.
6.2. The Information/Link Ratio
Does the paragraph or section consist largely of links?
In running text, there should not be more than a couple of links per paragraph. There should not be links in every paragraph, and there certainly must not be links in titles, subheadings, figure or table captions. Cross-references interrupt the flow of thought, and can actively interfere with the absorption of information. If the reader needs a lot of additional information, rethink the structure of the section, and enrich the quality of the information. Do not let the cross-references overpower the message. A solution is to add a sentence to the end of the section indicating where more information is available.
Note
Lists can be an exception, but try to provide the reader with a descriptive phrase or sentence for each cross-referenced item, as well as a lead-in and concluding sentence for the paragraph that contains the list.
6.3. The Repeatability Test
Does the information have to be repeated?
This is a hard one, and one that many authors abhor. Often the answer is yes. If the information is vital, and needs to appear in multiple places, it just has to be done. It's not a crime. In some circumstances, like online help, the reader wants the answer immediately. Do not force even one extra click on them. In a safety situation, it may be the only chance the reader has to find critical information quickly. Any vital information, that is not more than a couple of paragraphs, (or half a page, or 5 rows of a table) can be repeated rather than cross-referenced to.
Cross-referencing is a good servant but a poor master. Content still rules!
Chapter 7. Resources
This section lists some books and websites for you to consult on your quest to create the perfect document.
The guides that you refer to first are generally dictated by the type of material you are writing. It is important to establish this first because the guidelines in the following references sometimes contradict each other. This does not mean they are wrong; different audiences require different writing styles, and different references are sometimes required when you change styles. The following documentation types are recognized:
- Technical content: software manuals and documentation, user guides
- Technical collateral: white papers and technology briefs
- Marketing content: advertising, promotions, articles
- Corporate collateral: related to company or products
- Press releases

Part II. Usage Dictionary
The Usage Dictionary provides guidelines for the correct use of common terms in Red Hat documentation, which terms to avoid, and the preferred spelling if variations exist.
Chapter 8. 0-9
- 24x7, 24x7x365
- adj. Use "24x7" in most instances. Use "24x7x365" only to differentiate from others or highlight specifically that a service is offered every day of the year, for example, providing 24x7x365 phone support.
- 2-track (IT)
- adj. A less common way to refer to bimodal or hybrid IT. See bimodal IT
- 3-D
- adj., n.. Correct. Do not use 3D, 3-d, or other variations.
Chapter 9. A
- "&" and "+"
- Ampersands or plus signs can be used in design elements and graphics when space is limited, and when either referring to or quoting third-party content that uses them. Do not use them in original body copy.
- agile, agile development
- adj. Use only as an adjective. It is not a proper noun, nor is it owned or trademarked and should not be capitalized.
- air gap, air wall
- n. Use "air gap" to describe systems that are separated, not by software, but physically. Do not use "air wall." "Air gap" is preferred in technical publications because there is no actual wall that you need to breach, but rather a gap that you need to bridge. You cannot break through something that does not exist.
- a.m., am
- Correct. Use the lowercase form and include the periods, and use a preceding space.See also p.m..See The IBM Style Guide for a full discussion of how to represent times.
- all-in-one, allinone
- n., adj. Correct. Hyphenate in both cases. Do not use "allinone" or other variations.
- AMD64
- Correct. Do not use "Hammer," "x86_64," "x86-64," "x64," "64-bit x86" or other variations as the name of this architecture.The correct term for AMD's implementation of this architecture is "AMD64." When discussing the architecture generally, reference both AMD64 and Intel 64 implementations specifically.See also Intel 64.
Note
The AMD64 logo is trademarked; the term "AMD64" is not. For more information about AMD trademarks, see the AMD Trademark Information page at http://www.amd.com/us/aboutamd/Pages/trademarks.aspx.For more information about Intel® trademarks, see http://www.intel.com/content/www/us/en/legal/trademarks.html and http://www.intel.com/content/www/us/en/trademarks/trademarks.html. - ATM
- Initialism for Asynchronous Transfer Mode, a network technology based on transferring data in cells or packets of a fixed size. The cell size used with ATM is relatively small compared to units used with older technologies.
- above
- Do not use to refer to information mentioned previously. When documents are converted to online format, the information may no longer be "above." Use a cross-reference if the referenced material is sufficiently removed, or write "as mentioned previously" instead.
- acronyms
- An acronym is a word formed from the initial letters of a name, such as ROM for Read Only Memory, or by combining initial letters or part of a series of words, such as LILO for LInux LOader. Note that an acronym is pronounced as a word. Compare this to an initialism, which is also formed in a similar fashion to an acronym, but in which each letter is pronounced separately.Spell out most acronyms and initialisms before using them in text, such as "The Embedded DevKit (EDK)..." Unless the acronym or initialism stands for a proper noun, use sentence case for the spelled out version - for example, "central processing unit (CPU)." Unless required for the audience or the topic, do not spell out well-known abbreviations, such as HTML.To form the plural of an acronym, add a trailing, lowercase "s," or "es," for example, ROMs, PINs, BIOSes.
- alternate
- vb. "Alternate" as a verb means to change between two states or options.See also alternative.
- alternative
- adj. Used to describe another way or method of doing something. "Alternate" (vb.) means to change between two states or options. If you mean "another way of doing something," use "an alternative method is to..."See also alternate.
- and/or
- Avoid if possible. Try to rewrite to make the available options explicit and clear. Do not write this and/or that. Write this or that or both.
- application
- When used as a proper name, use the capitalization of the product, such as GNUPro, Source-Navigator, and Red Hat Enterprise Linux. When used as a command, use lowercase as appropriate, such as "To start GCC, type gcc."
Note
"vi" is always lowercase. - Applixware, Applix, ApplixWare
- Correct. Do not use "Applix" or "ApplixWare."
- architect
- Do not use as a verb. Even though it might make sense in the correct context, using it as a verb can be jargon or unclear for your audience. Use "design," "build," "create," or another descriptive verb instead. Before replacing the verb form of "architect" during the editing process, check with the writer to find out the intended meaning. For example, a sentence that mentions rearchitecting might require "refactoring" as a replacement rather than "rebuilding."
- as well as
- Not interchangeable with "and." "As well as" used in a series places more emphasis on the items preceding it, whereas "and" places equal weight on all items in the series. For example, "We sell kitchen electronics and china, as well as some gourmet foods." But "We sell kitchen electronics, china, and silverware."
- as-a-Service
- Be aware that there is a great deal of overlap in as-a-Service acronyms. To avoid confusion, always spell out the full term on first use.
- DRaaS (Disaster Recovery-as-a-Service)
- CaaS (Cloud-as-a-Service, Communications-as-a-Service, Containers-as-a-Service)
- UCaaS (Unified Communications-as-a-Service)
- FaaS (Function[s]-as-a-Service)
- SaaS (Search-as-a-Service, Security-as-a-Service, Storage-as-a-Service, or Software-as-a-Service)
- PaaS (Payments-as-a-Service, Platform-as-a-Service)
- MaaS (Messaging-as-a-Service)
- SECaaS (Security-as-a-Service)
- TDBaaS (Time-series Database-as-a-Service)
When using as-a-Service acronyms:- Capitalize the noun (e.g., Platform, Software, Infrastructure) and Service, both when abbreviated and written out.
- When in all capitals, such as a title or headline, the "aa" in the acronym remains lowercase (e.g., INTRODUCTION TO PaaS SOLUTIONS).
- Hyphenate when written out: Thing-as-a-Service. For two-word prefixes, do not include a hyphen between the first and second words: Mobile Backend-as-a-Service. Can be used as an adjective to describe multiple (e.g., when referring to an IaaS, PaaS, and SaaS, use as-a-Service offerings, as-a-Service products, or similar wording).
- Avoid an acronym if it could stand for more than one term in a single asset (e.g., if you're writing content that discusses both Cloud-as-a-Service and Containers-as-a-Service).
- autofs
- Always lowercase. This refers to the kernel-based automount utility. No other forms are recognized.
Chapter 10. B
- back end, back-end
- n. Two words. Refers to software that performs the final stages of a process, or tasks that are not visible to the user. For example, "each back end provides a set of calls."adj. Hyphenate. For example, "when the back-end database processes a search operation…"Do not use "backend."See also front end, front-end
- backup, back up
- Depending on usage, this could appear in either of two ways:
- adj. One word. For example, "store the backup copies of important files in a secure location."
- n. One word. For example, "create a backup of your important files."
- v. Two words. For example, "always back up important files."
Do not use the hyphenated form, "back-up." - backtrace
- n. "Backtrace" is the most common term used to refer to a stack trace (or stack backtrace), which is a report of the active stack frames (that is, function calls) at a certain point in time during the execution of a program. In contrast, the Python programming language calls its stack trace a "traceback," possibly because the stack frames are printed in the opposite order of those presented by gdb, the GNU Debugger. "Traceback" is the preferred term when referring to a Python stack trace.
- backwards
- Avoid using "backwards" unless you are stating that something has "backwards compatibility."
- backwards compatible
- Correct. Use to refer to something that is compatible with older equipment or previous versions of software. See also forwards compatible.
- bandwidth
- Correct. Bandwidth can refer to a range within a band of frequencies or wavelengths, or the amount of data that can be transmitted in a fixed amount of time.
- bare metal, bare-metal
- n. Two words.adj. Hyphenate.
- basically
- Do not use. For example, removing the word "basically" in the following sentence strengthens it: "This is how it is basically done." See also simply.
- because, since, as
- Do not use "since" or "as" to mean "because"; it is ambiguous. Use "because" to refer to a reason. Use "since" and "as" to indicate the passage of time.
- below
- Do not use to refer to information mentioned "below," or later in a document. When documents are converted to online format, the information may no longer be "below." Use a cross-reference instead.
- big data
- n., adj. Always use lowercase. Do not capitalize except at the beginning of a sentence, or if it is part of a Red Hat product, service, solution, or business unit name. See also cloud. Big data is also never hyphenated, per AP style, even when used as a complex adjective.
- bimodal IT
- Gartner phrase for the combination of traditional (mode 1 or type 1) and modern (mode 2 or type 2) IT infrastructure and resources. There are many ways to talk about this combination approach; be sure you use the right phrase for your audience. Using only the Gartner term can alienate other analysts or those not familiar with Gartner's phrasing.The practice of having both modes together is often referred to as hybrid, agile, or modern IT.
Note
Hybrid IT is a more general term, e.g. it could mean on-premise plus public cloud. Agile and modern IT can both carry an implication of "mode 2", so when using those terms, be specific about the exact technology combination you mean. - bimonthly, biweekly, semiweekly, semimonthly
- People have trouble remembering if biweekly means "every two weeks" or "twice a week." Semiweekly has a similar problem. Even though both terms have clear dictionary definitions, we recommend that you avoid them in favor of clear communication.Instead of biweekly, write "every two weeks" or "every other week."Instead of semiweekly or semimonthly, write "twice a week."
- BIND
- This is correct when referring to the DNS software. Do not use Bind.
- BIOS
- Correct. The plural form is BIOSes.
- bit rate
- Correct. Do not use "bitrate."
- Boolean
- Correct. Named after George Boole, who first developed the concept.According to The IBM Style Guide, it is acceptable to use "boolean" in API programming information when it refers to a primitive return type.
- boot
- v. To load the first piece of software that starts a computer. Because the operating system is essential for running all other programs, it is usually the first piece of software loaded during the boot process.n. Refers to the starting-up of a computer, which involves loading the operating system and other basic software. A cold boot refers to starting a computer that is turned off. A warm boot refers to resetting a computer that is already running.Boot is an abbreviation of bootstrap, which in olden days was a strap attached to the top of your boot that you could pull to help get your boot on. Hence, the expression "pull oneself up by the bootstraps." Similarly, bootstrap utilities help the computer get started.
- boot disk
- Two words. Do not use "boot diskette."
- boot loader
- Two words. Do not use "bootloader."
- bottleneck
- One word. Do not use "bottle neck" or "bottle-neck."A bottleneck refers to the delay in transmission of data through the circuits of a computer's microprocessor or over a TCP/IP network. The delay typically occurs when a system's bandwidth cannot support the amount of information being relayed at the speed it is being processed. There are, however, many factors that can create a bottleneck in a system.
- bpp
- Initialism for bits per pixel. All letters are lowercase, unless at the beginning of a sentence. Use a non-breaking space between the numeral and the units. For example, "16 bpp," not "16bpp."
- Bps, bps
- The abbreviation of bytes per second is Bps. The abbreviation of bits per second is bps. To avoid confusion, do not use at the beginning of a sentence. See also bandwidth.
- breadcrumb trail
- See The IBM Style Guide for initial guidance on how to use this term.
Note
Do not confuse the breadcrumb trail with the name of the actual page in a user interface. The final breadcrumb in the trail is the name of the page, unless the page itself offers a distinct title. The breadcrumb trail indicates the path taken to reach the current page. - break
- (v.) Do not use to mean "break the system" or similar. For example, "applying an unapproved patch might break the system." Choose an alternative such "cause the system to fail."
- bring up
- Do not use. Use "open" instead.
- Britain
- If referring to the language, say "English." If referring to the country, say the United Kingdom of Great Britain and Northern Ireland, or the UK. Using Britain or British is usually wrong and to some implies a specific subjective statement about the state of Northern Ireland.
- broadcast
- To simultaneously send the same message to multiple recipients. Broadcasting is a useful feature in email systems. It is also supported by some fax systems.In networking, a distinction is made between broadcasting and multicasting. Broadcasting sends a message to everyone on the network whereas multicasting sends a message to a select list of recipients.
- Btrfs
- A copy-on-write file system for Linux. Use a capital "B" when referring to the file system. When referring to tools, commands, and other utilities related to the file system, be faithful to those utilities.See http://en.wikipedia.org/wiki/Btrfs for more information on this file system.See http://en.wikipedia.org/wiki/List_of_file_systems for a list of file system names and how to present them.
- bug fix
- Two words. Do not use "bugfix."
- built-in
- adj. Hyphenate. Do not use "builtin" unless referring specifically to "Bash builtins" or if it is otherwise a proper noun.
- bunches of
- Do not use, unless "bunch" is a specific term used in the software being documented. Use "many" or some other alternative instead.
- button
- Describe a GUI button as a "button," not a "pushbutton" or "push-button."Ordinarily you would not include the text "button" in a procedure or description. For example, "Click to continue" is perfectly acceptable. It may be necessary to distinguish between buttons and links; for example, "Click the button."
Chapter 11. C
- can, may
- Use "can" to describe actions or conditions that are possible. Use "may" only to describe situations where permission is being given. If either "can," "could," or "may" apply, use "can" - it is less tentative.
- cannot
- Correct, when used in the negative form. For example, "you cannot end a sentence with a preposition." Do not use "can not." When used as an additive, use two words. For example, "you can not only end a sentence with a preposition, but you can also start a sentence with a conjunction."
- CapEx, OpEx
- Correct. These stand for "capital expenditures" and "operating expenses" respectively. Do not use alternative capitalization.
- cd, CD
- When referring to the change directory command, use
cd.When referring to a compact disk, use "CD." For example, "Insert the CD into the CD drive." The plural is "CDs."See the Word Usage appendix of The IBM Style Guide for more information. - CD #1
- When referring to a specific CD in the Red Hat Enterprise Linux CD set, it is correct to refer to it as: Red Hat Enterprise Linux CD #1. Avoid using Red Hat Enterprise Linux CD 1
- Ceph
- cgroup
- Correct (all lowercase) when referring to the kernel-based technology. This is a contraction of control group, and not a proper noun in itself; proper nouns use initial caps. This being the case, it is permissible to capitalize if used at the beginning of a sentence.Where cgroup refers to something else, for example, a package name, file name, and so on, use a literal rendition.
- characters
- Do not use "characters" when you should use "bytes." In English, bytes and characters can be used interchangeably; in other languages a single character may consist of multiple bytes.In computer software, any symbol that requires one byte of storage. This includes all the ASCII and extended ASCII characters, including the space character. In character-based software, everything that appears on the screen, including graphics symbols, is considered to be a character. In graphics-based applications, the term character is generally reserved for letters, numbers, and punctuation.
- check
- Avoid. Use "verify," "make sure," "ensure," or "read," depending on the context.
- check box
- n. Two words. Do not use "checkbox" or "check-box."
- chipset
- n. One word. Do not use "chip set" or "chip-set."
- CI/CD
- Define on first use; generally continuous integration/continuous delivery. This is not continuous development, a term with questionable usefulness and only marginal adoption.
- ciphertext
- n. One word. Do not use "cipher text" or "cipher-text" or other variants.
- click
- v. Use when referring to a GUI control button, for example, "Click ."See the Word Usage appendix of The IBM Style Guide for more information.
- client-side, client side

IP Masquerade, also called IPMASQ or MASQ, allows one or more computers in a network without assigned IP addresses to communicate with the internet using the Linux server's assigned IP address. The IPMASQ server acts as a gateway, and the other devices are invisible behind it, so to other machines on the internet the outgoing traffic appears to be coming from the IPMASQ server and not the internal PCs.Because IPMASQ is a generic technology, the server can be connected to other computers through LAN technologies such as Ethernet, Token Ring, and FDDI, as well as dial-up connections such as PPP or SLIP.
- IPsec
- IPsec stands for Internet Protocol security. According to its RFC, IPsec should be used. Do not use "IPSec."
- IP switching
- A new type of IP routing developed by Ipsilon Networks, Inc. Unlike conventional routers, IP switching routers use ATM hardware to speed packets through networks. Although the technology is new, it appears to be considerably faster than older router techniques.
- ISV
- Short for independent software vendor, a company that produces software.
- IT/I.T.
- Use "I.T." (with periods) only in headlines or subheadings where all caps are used, in order to clarify that the word is "IT" vs. "it."
- Itanium
- A member of Intel's Merced family of processors, Itanium is a 64-bit RISC microprocessor. Based on the EPIC (Explicitly Parallel Instruction Computing) design philosophy, which states that the compiler should decide which instructions be executed together, Itanium has the highest FPU power available.In 64-bit mode, Itanium is able to calculate two bundles of a maximum of three instructions at a time. In 32-bit mode, it is much slower. Decoders must first translate 32-bit instruction sets into 64-bit instruction sets, which results in extra-clock cycle use.Itanium's primary use is driving large applications that require more than 4 GB of memory, such as databases, ERP, and future internet applications.Do not use the term IA64. It can be used in file names because they are not printed in the content.
- Itanium 2
- Itanium 2 is correct. Do not use "Itanium2" and always use a non-breaking space between "Itanium" and "2."

- load balancing
- Distributing processing and communications activity evenly across a computer network so that no single device is overwhelmed. Load balancing is especially important for networks where it is difficult to predict the number of requests that will be issued to a server. Busy websites typically employ two or more web servers in a load balancing scheme. If one server starts to get swamped, requests are forwarded to another server with more capacity. Load balancing can also refer to the communications channels themselves.
- logical topology
- Also called signal topology. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The physical topology is the way that the workstations are connected to the network through the actual cables that transmit data - the physical structure of the network. The logical topology, in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices.

The loopback interface has no hardware associated with it, and it is not physically connected to a network.The loopback interface allows IT professionals to test IP software without worrying about broken or corrupted drivers or hardware.
- lots of
- Do not use. Use "many" instead.
- LPAR
- Abbreviation of logical partitioning, a system of taking a computer's total resources, such as processors, memory, and storage, and splitting them into smaller units that can be run with their own instance of the operating system and applications. Logical partitioning, which requires specialized hardware circuits, is typically used to separate different functions of a system, such as web serving, database functions, client/server actions, or systems that serve multiple time zones or languages. Logical partitioning can also be used to keep testing environments separated from production environments. Because the partitions act as separate physical machines, they can communicate with each other. Logical partitioning was first used in 1976 by IBM.

The program begins the boot process by looking up the partition table to determine which partition to use for booting. It then transfers program control to the boot sector of that partition, which continues the boot process. In DOS and Windows systems, you can create the MBR with the FDISK /MBR command.
- media
- Objects on which data can be stored. These include hard disks, diskettes, CDs, and tapes.

- network transparency
- A condition in which an operating system or other service allows the user access to a remote resource through a network without needing to know if the resource is remote or local. For example, Sun Microsystems" NFS, which has become a de facto industry standard, provides access to shared files through an interface called the Virtual File System (VFS) that runs on top of the TCP/IP stack. Users can manipulate shared files as if they were stored locally on the user's own hard disk.
- NFS
- Abbreviation of Network File System, a client/server application designed by Sun Microsystems that allows all network users to access shared files stored on computers of different types. NFS provides access to shared files through an interface called the Virtual File System (VFS) that runs in a layer above TCP/IP. Users can manipulate shared files as if they were stored locally on the user's own hard disk.With NFS, computers connected to a network operate as clients while accessing remote files, and as servers while providing remote users access to local shared files. The NFS standards are publicly available and widely used.
- node

- User-triggered automation.
- Ready-to-use/ready-to-deploy.
- Self-service/self-provisioned.
- Single-step automation.
- On-demand automation.
- PXE

- RAM disk
- Correct. Do not use "RAMdisk," "ramdisk," or "RAdisk."Refers to RAM that has been configured to simulate a disk drive. You can access files on a RAM disk as you would access files on a real disk. RAM disks, however, are approximately a thousand times faster than hard disk drives. They are particularly useful, therefore, for applications that require frequent disk accesses.
- raw
- Unprocessed. The term refers to data that is passed to an I/O device without being interpreted. In contrast, cooked refers to data that is processed before being passed to the I/O device.The term comes from UNIX, which supports cooked and raw modes for data output to a terminal. In cooked mode, special characters, such as erase and kill, are processed by the device driver before being sent to the output device.
- raw data
- Information that has not been organized, formatted, or analyzed.
- read
- v. To copy data to a place where it can be used by a program. The term is commonly used to describe copying data from a storage medium, such as a disk, to main memory. Also used to refer to the act of determining the contents of a variable or parameter.n. The act of reading. For example, a fast disk drive performs 100 reads per second.

- remote access
- The ability to log onto a network from a distant location. Generally, this implies a computer, a modem, and some remote access software to connect to the network. Whereas remote control refers to taking control of another computer, remote access means that the remote computer actually becomes a full-fledged host on the network. The remote access software dials in directly to the network server. The only difference between a remote host and workstations connected directly to the network is slower data transfer speeds.
- remote access server
- A server that is dedicated to handling users that are not on a LAN but need remote access to it. The remote access server allows users to gain access to files and print services on the LAN from a remote location. For example, a user who dials into a network from home using an analog modem or an ISDN connection will dial into a remote access server. After the user is authenticated they can access shared drives and printers as if they were physically connected to the office LAN.
- required
- See must.
- return
