Finding Help

Each command on your computer includes a manual page—or man page—that contains a list of the options available. Man pages are traditionally rather terse and intended only for referencing the different ways the command should be used. For a friendlier introduction to using commands, we recommend a Google search.

To view a man page (such as the man page for ls), run:

username@computer:~$ man ls

The man page command itself has a number of options (run man man to see them), and one of the most useful is -k. This option allows you to search the man pages for a particular word. This is useful when you don't remember the command. As an example, you could find all commands related to processes by running:

username@computer:~$ man -k processes

The remainder of this appendix gives a brief introduction to some of the more common and useful commands you will encounter and want to learn, organized in categories based on how they are used. We will end with a short list of some other resources for further research.
