Perl one-liner: which directories do I need to restore?

I just ran an automatic process on a directory much higher up in the file system hierarchy than I wanted. Specifically, I accidentally did a Subversion Import on /Users from Xcode SCM dialog.

I can't just do a blanket restore starting at that top level directory. Specifically, Time Machine won't let me restore /Users. I quit Xcode shortly into the operation, and I need to know which subdirectories got hit so I can restore those.

How to do this? Do a find on which files were modified, then parse the output.

$ sudo find /Users -mmin -15 -ls >/tmp/screwup.list 2>&1

jbm@Foucault:~
$ perl -ane '$p{join(" ", (split("/", $F[10]))[1..4])}++; END {for $i (keys %p) {print "$i\n";}}' /tmp/screwup.list
