Capture a list of all installed commands


if I open a terminal and hit [TAB] [TAB] it will display "Display all 2583 possibilities? (y or n) ". If I press y is there a way to capture the output and write it to a file?

Not like it is a command so I can't just use a redirect to a file? If not I guess I could just do an ls on all locations of $PATH and capture that to a file.

Will do (in a not so elegant manner) do what you want.

I'm not used to programmable tab completion and maybe there is a better way, but you can obtain that list using
Code:
compgen -c "" | sort -u
where -c is meant to generate a completion list using only command names and "" is the null string... the same you DID NOT type before [TAB][TAB]...

On my system that lists ANYTHING with an x-flag, that
includes directories....

I think that you will find that all the 'commands' listed equate to all the files in /bin and /usr/bin - I believe that these are determined by your path setting. Type $PATH in a terminal/console to see what your bash settings are. Therefore, a simple listing to a text file will accomplish what you appear to want, try:
Quote:
ls /usr/bin > commands.txt

[TAB] [TAB] does list all the files in my $PATH. So I guess the best way is to just do like you said minrich and redirect the ls to somewhere.

That's strange. The -c option should limit the result to command names. I've just tried the compgen command on different systems (OpenSuse, CentOS, Vectorlinux) and it gives the list of commands only. Hmmm... I should investigate...

More like
Code:
for i in $(echo $PATH|tr -d '.'| tr ':' ' '); do find $i -type f  ; done
