cp --verify?
I don't see a --verify switch on cp, so I presume it does not. Is there an automated way to ensure a copy has gone well byte-for-byte without writing a script to filter diff? I want to be relatively sure my family pics are in the destination and not currupted before I wipe my flash card - got burned by ms windows on that bigtime last year...

I want to be relatively sure If you use the diff command and specify directories, it will compare the contents of each, as well as comparing all the files byte for byte. Check "man diff" -- there should also be an option to check down through any subdirectories as well. -Rob ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Note that one will have to run it twice; the first time to copy and the second time to verify that rsync does not want to update any files there (if it did it would be an indication of corruption). -c makes it checksum regardless of whether the file size/ctime matches, but it will not make it re-do the checksumming after an update. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <[EMAIL PROTECTED]>' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org pgpHF8ZZI7HBx.pgp Description: PGP signature
