There are many mp3 files with initial "Various - ...", like:
Various - Beethoven:Symphony No.5-Allegro Con Brio.mp3
Now I want to remove the "Various - " in the file name, to "Beethoven:Symphony No.5-Allegro Con Brio.mp3".
In zsh we have a tool called zmv can do this job. Firstly we have to use autoload zmv to activate it. Then use "-n" option to print the result without actually performing the rename operation. When it is ok, remove the -n option to rename all the files:
zmv -n '(*).mp3' '${1//Various\ -\ /}.mp3'
zmv '(*).mp3' '${1//Various\ -\ /}.mp3'
