List files with certain extensions with ls and grep


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$ | grep \.mp3$ | grep \.exe$

But no, as the first grep will output just mp4's therefor the other 2 grep's won't be used.

Any ideas? PS, Running this script on Slow Leopard.

Why not:

ls *.{mp3,exe,mp4}

I'm not sure where I learned it - but I've been using this.

Use regular expressions with find:

find . -iregex '.*\.\(mp3\|mp4\|exe\)' -printf '%f\n'

If you're piping the filenames:

find . -iregex '.*\.\(mp3\|mp4\|exe\)' -printf '%f\0' | xargs -0 dosomething

This protects filenames that contain spaces or newlines.

OS X find only supports alternation when the -E (enhanced) option is used.

find -E . -regex '.*\.(mp3|mp4|exe)'
