You know that if you play How to Dismantle an Atomic Bomb backwards, you hear Bono giving complete and easy to follow instructions on how to build one?
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
mv 'Dan Jones/Get Sounds Now' 'Dan Jones/ Get Sounds Now' mv 'Dan Jones/One Man Submarine' 'Dan Jones/ One Man Submarine' mv 'Tripping Daisy/Jesus Hits Like the Atom Bomb' 'Tripping Daisy/ 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 …
