Extend your bash completion !!

I have downloaded zip file, I wanna extract it on command line.

$ unzip [tab][tab] -> if it displays only zip files instead of all files is that won't be good ?

Yes !!

here you go :

put below line(s) in your .bashrc file or in .bash_profile you are done with it !!

complete -A file -X '!*.zip' unzip

for other completions :

complete -A file -X '!*.php' php

complete -A file -X '!*.pl' perl

complete -A file -X '!*.c' gcc

complete -A file -X '!*.sh' bash

complete -A file -X '!*.gz' gunzip

complete -A file -X '!*.tgz' gunzip

complete -A file -X '!*.Z' gunzip

complete -A file -X '!*.gz' tar

complete -A file -X '!*.tgz' tar

complete -A file -X '!*.Z' tar

complete -A file -X '!*.awk' awk

complete -A file -X '!*.sed' sed

complete -A file -X '!*.zip' unzip

now you can get completion for php,perl or create for any of your favorite language.
