APROPOS


Because Linux knows so many commands you can impossibly remember them all, that is why there are a few tricks available to help you.
We already know from previous tips that if you type the first few characters of a command and press the <tab> key, it will autocomplete the command or give a list of options.
Also we had the whatis command a few tips ago this showed a line of text explaining what a command was for.

Here is another clever command: “apropos”. Imagine you know only a part of the name or description of a command, let's take an example like “alsa”:

CODE
$ apropos alsa


Returns to the screen:

arecord [aplay]  (1)  - command-line sound recorder and player for ALSA soundcard driver
aseqnet              (1)  - ALSA sequencer connectors over network


Well, that is pretty cool isn't it ?? . . . . . . . cool ?:
