I just got a new fileserver and have copied the files off of my old fileserver onto this shiny new one.
Before I take my old filesever offline, I would like to compare the files on both machines to insure that nothing got corrupted during the copy process.
Is there a command that I can use to do this in one shot? I have been playing around with diff and the best I can do is to get it to give me a list of "common subdirectories", but it's not comparing the actual files. It took all night to copy the files so I'd think a real compare would take twice that long, and everything that I try with diff seems to run in a few seconds.

Check out the "-r" option of diff.

diff -r --brief directory1 directory2

Try rsync -avcn. (The "n" will tell it to not actually do anything, just print what it would have done.) And the -c makes it do a checksum of every file.
Thanks guys.
