Easily convert a list of files from .wma to .mp3 in Ubuntu using bash and ffmpeg

Here's a simple one liner to convert all the .wma files in a folder to .mp3's.  Update! For a GUI way... check out  FormatJunkie.

1. Open a terminal (Ctrl+Alt+t)
2. cd to the folder containing the .wma files
3. Enter this:

for f in *.wma;do ffmpeg -i "$f" -acodec libmp3lame -ab 192k -ac 2 -ar 48000 "$(echo $f| head -c -5).mp3";done

4. Press enter and let it go.

5. Cleanup (Warning: this will delete the old .wma files so make sure you back them up if you need them!)

 for f in *.wma;do rm "$f";done

How does it work?
