1.6. Conventions Used in this Document
The following conventions are used in this document and are outlined here for those who may not yet have a complete understanding of how to access and control the underlying operating system in Linux, which is usually via the Bash shell.
First, filenames are referenced in a paragraph like so: /path/file
Commands in Linux are executed (or 'called') at the command prompt, otherwise known as the 'command line.' If you are in the non-graphical (text-based) environment, you will usually be presented with the Bash shell prompt which is a dollar sign:
...or the hash mark:
...if you have logged in as root or have otherwise acquired root, or 'superuser' privileges. You can also access the Bash shell in the X window system, otherwise known as X or X11, with an xterm or similar X-terminal-emulator. Commands to be performed at the Bash prompt, but referenced in a paragraph of this document, usually look like this: do this now
Commands and/or the resulting output of commands may also be outlined with screen output in their own paragraph or heading:
$ date Sun Jul 27 22:37:11 CDT 2003
When a command is written in front of the Bash prompt (e.g., $ date above), it is assumed the [Return] or [Enter] key has been pressed after the command, possibly followed by the output on a new line (e.g., as in the date in the above example).
