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 chapter 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 end with a short list of some other resources for further research.
