Mac::Glue
Merging two old photo libraries (one that constantly made iPhoto crash that worked well when upgraded to iPhoto 5 with other old ones that I used to make iPhoto 2 quicker) I came across Cleaning iPhoto and Mac::Glue. So a quick:
<br /> perl -MCPAN -e 'install "Mac::Glue"'<br /> gluemac /Applications/iPhoto.app<br />
and off I was using his scripts to compare MD5 hashes. I'll be using Mac::Glue to do the same cleaning up for iTunes where my duplicate count is getting higher quickly.
And in case you're one of my friends who know I don't like perl, I still don't. But the alternative was AppleScript
