As Stomp mentioned before rsync is a good match for this type of problem.

It offers a --dry-run option that allows reporting on any differences and what would be done to update them. It has many configuration options for example: supports just comparing filenames+date+time or doing a full CRC check of each file, removing files no longer present on the master server, compressing data as it's transferred between the servers, bandwidth capping for reduction on network impact, preserving file ownership and permissions, etc.

Please always tell us what operating system you're using when you start a thread like this.

Some systems have a utility named dircmp that, among other things, can tell you what files are missing from either of two directories given as operands and, for files that are present in both directories, tell you whether or not the contents of those pairs of files have the same contents.
