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

Why not:

ls *.{mp3,exe,mp4}

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

Answer 2

ls -R | findstr ".mp3"

ls -R => lists subdirectories recursively

Answer 3

egrep -- extended grep -- will help here

ls | egrep '\.mp4$|\.mp3$|\.exe$'

should do the job.

Answer 4

In case you are still looking for an alternate solution:

ls | grep -i -e '\\.tcl$' -e '\\.exe$' -e '\\.mp4$'

Feel free to add more -e flags if needed.

Answer 5

the easiest way is to just use ls

ls *.mp4 *.mp3 *.exe

Answer 6

For OSX users:

If you use ls *.{mp3,exe,mp4}, it will throw an error if one of those extensions has no results.

Using ls *.(mp3|exe|mp4) will return all files matching those extensions, even if one of the extensions had 0 results.
