I use the command line utility youtube-dl to download videos from YouTube and make mp3s from them with avconv. I'm doing this under Ubuntu 14.04 and very happy with it.

The utility downloads the files and saves them with the following name scheme:

TITLE(artist-track)-ID.mp3

So an actual filename looks like:

EPIC RAP BATTLE of MANLINESS-_EzDRpkfaO4.mp3

Some other file names in the folder look like:

EPIC RAP BATTLE of MANLINESS-_EzDRpkfaO4.mp3
Martin Garrix - Animals (Official Video)-gCYcHz2k5x0.mp3
Stromae - Papaoutai-oiKj0Z_Xnjc.mp3

At first, this was no problem. It didn't bother me while listening to my music in Rhytmbox. But when moving to phone or other devices it is pretty confusing to see a so long name, and some players, like the Samsung ones, treat that last part (id after second dash) of the name as Album or something.

I'd like to create a bash script that removes what's after the second dash in the name for all files, so it'll make them like this:

From: Martin Garrix - Animals (Official Video)-gCYcHz2k5x0.mp3

To: Martin Garrix - Animals (Official Video).mp3

Is it also possible to instruct youtube-dl to exclude the ID from now on?

I am currently downloading with the command:

youtube-dl --extract-audio --audio-quality 0 --audio-format mp3 URL
