Johnny Matthews | Remove crap from your music library

Over the years I've accumulated a bunch of crap in my music library. Lots of `DS_Store` and `.dat` files, bouncing around for no particular reason. I found out that I can clean everything up with just a couple of commands! This was written on 4th of May 2021.

Remove crap from your music library

Run this to get rid of all your crap:

grep --exclude=\*.{mp3,Mp3,m4a,flac,jpg,jpeg,png,wav} --exclude-dir=Playlists --recursive --line-number -wl . > ~/delete-these
for f in delete-these; do rm ${f}; done;

The first runs through your library and finds any file that doesn’t have any of the listed extensions. It also ignores the Playlists folder - there’s a lot of crap in there that I’m not ready to touch just yet. Any file the command finds is added to a file called delete-these.

The second line foreaches through each line in delete-these and deletes the corresponding line in that file. The delete-these file looks something like this:

...
EDEN/End Credits/.DS_Store
EDEN/Crazy In Love/.DS_Store
The Home Team/Better Off (2018)/._.DS_Store
The Home Team/Better Off (2018)/.DS_Store
...

It’s worth mentioning that you need to be within your Music folder for these two lines to actually do anything useful. Also, the deletion in the second command is irreversable. Once it’s ran, you’re not getting that stuff back.
