Conventions Used in This Book (Mac OS X for Unix Geeks)

0.5. Conventions Used in This Book

The following typographical conventions are used in this book:

Italic: Used to indicate new terms, URLs, filenames, file extensions, directories, commands and options, Unix utilities, and to highlight comments in examples. For example, a path in the filesystem will appear in the text as /Applications/Utilities.
Constant width: Used to show functions, variables, keys, attributes, the contents of files, or the output from commands.
Constant width bold: Used in examples and tables to show commands or other text that should be typed literally by the user.
Constant width italic: Used in examples and tables to show text that should be replaced with user-supplied values.
Menus/Navigation: Menus and their options are referred to in the text as File Open, Edit Copy, etc. Arrows will also be used to signify a navigation path when using window options; for example: System Preferences Accounts Users means that you would launch System Preferences, click the icon for the Accounts control panel, and select the Users pane within that panel.
Pathnames: Pathnames are used to show the location of a file or application in the filesystem. Directories (or folders for Mac and Windows users) are separated by a forward slash. For example, if you see something like, "...launch the Terminal application (/Applications/Utilities)" in the text, that means the Terminal application can be found in the Utilities subfolder of the Application folder.
%, #: The percent sign (%) is used in some examples to show the user prompt for the tcsh shell; the hash mark (#) is the prompt for the root user.

TIP: These icons signify a tip, suggestion, or a general note.

WARNING: These icons indicate a warning or caution.
