batch renaming iTunes directories

In partial response to the Ask Metafilter question “How can I rename my music folders on my Mac based on ID3 tags?“:

#!/bin/bash
# itunes_sanity.sh - fix dir names created by iTunes
# only works for mp3s, and not actually tested on a Mac
# created by scruss on Sun Sep 4 22:05:00 EDT 2005

find "$@" -type d -mindepth 1 | while read directory
do
  artistdir=$(dirname "$directory")
  firstfile=$( find "$directory" -type f -iname '*.mp3' | head -n1 )
  year=$( id3info "$firstfile" | egrep ' TYE ' | sed 's/=== TYE (Year): //; s/[^0-9]*//;' )
  album=$( id3info "$firstfile" | egrep ' TAL ' | sed 's,=== TAL (Album/Movie/Show title): ,,;' )
  echo mv \'$directory\' \'$artistdir/\[$year\] $album\'
done

So if you were in the terminal, in your music library (one up from the individual artist directories), and you did:

itunes_sanity.sh Dan\ Jones Tripping\ Daisy

you’d get:

mv 'Dan Jones/Get Sounds Now' 'Dan Jones/[2005] Get Sounds Now'
mv 'Dan Jones/One Man Submarine' 'Dan Jones/[2003] One Man Submarine'
mv 'Tripping Daisy/Jesus Hits Like the Atom Bomb' 'Tripping Daisy/[1998] Jesus Hits Like the Atom Bomb'

If that looks okay, run the output through the shell:

itunes_sanity.sh Dan\ Jones Tripping\ Daisy | sh

and all should be well.

You’ll need id3lib, which is probably most easily installed from Fink. Also, this only works for mp3 files; I can’t grok the tag info for AAC files. And finally, this might go seriously screwy on weird characters in filenames. You know my feelings on that …
