rsync is something like that and very effective. from the man page : The rsync remote-update protocol allows rsync to transfer just the differences between two sets of files across the network link, using an efficient checksum-search algorithm described in the technical report that accompanies this package. the technical report included in the debian package explains it all. hope that helps. -- ///\\/\\/\\\\/\\\/\\/\/\/\\\/\//\\\////\\\///\\/\/\// Patrick [EMAIL PROTECTED] http://www.patoche.org/
