[gentoo-user] comparing two complex directories

[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?

I've had good luck with dev-util/dirdiff before...

	star -c -diff -v -C from-dir . to-dir

Check diffopts= to learn how to tell star what to compare.

It is fast, compares all file attributes and it does not go into loops if you 
encounter symlinks to directories.
