Hi Gabor, You can use rsync. rsync -avn a b -n is the flag for dry-run. If you add the flag -c then it will compute the checksum for every file. If -c is not used, then it will relay on timestamp and size of file for comparison.
output: $ rsync -avn a b sending incremental file list a/ a/file sent 74 bytes received 19 bytes 186.00 bytes/sec total size is 23.29K speedup is 250.47 (DRY RUN) Investigate the -q option if you want to use this command from a script.
