List files with certain extensions with ls and grep

Question

I just want to get the files from the current dir and only output .mp4 .mp3 .exe files nothing else. So I thought I could just do this:

ls | grep \\.mp4$ | g         


        

Answer 1

No need for grep. Shell wildcards will do the trick.

ls *.mp4 *.mp3 *.exe

If you have run

shopt -s nullglob

then unmatched globs will be removed altogether and not be left on the command line unexpanded.

If you want case-insensitive globbing (so *.mp3 will match foo.MP3):

shopt -s nocaseglob
