[gentoo-user] comparing two complex directories

[James]

All,

I'm trying to find a good way to compare two complex directory
structures to see what files differ. I've looked at a few different
options:

- rsync dry run (someone said this should work, but I'm having trouble
getting good information out of this)
- diff -rq (this works, but it's sloowwwwww)

I've used cdircmp before but it tends to crash on complex directories
(a directory with more than a few subdirs and with hidden dot files).

Thoughts? Any specific / good utilities for doing this?
