2.3.3 Keyword Lookup with apropos

Suppose you know what you want to do, but you're not sure of the command to use. Then the apropos command is helpful. This command locates commands by keyword lookup. The apropos command lists all commands whose one-line summaries contain any keywords you supply. This can lead to a very lengthy display, as some keywords may appear in many places.

For some examples of apropos output, try entering one or more of the following:

• apropos who

• apropos execute

• apropos apropos

If you do enter a keyword that generates an unreasonably lengthy display, pressing Ctrl-C interrupts the display and returns you to the command prompt. (Hold down the Control key and press "c".)
