I should know this, but ..
I'm moving hundreds of thousands of files from USB drives to a new destination drive.
I've used rsync to make a copy of the files which is great.
But I need to ensure all the files are exact copies. I don't think rsync has a "hash destination and report disagreements with source" feature. Hi,
You can use rsync using the --checksum (short -c) option manpage: -c, --checksum This changes the way rsync checks if the files have been changed and are in need of a transfer. Without this option, rsync uses a "quick check" that (by default) checks if each file’s size and time of last modification match between the sender and receiver. This option changes this to compare a 128-bit checksum for each file that has a matching size.
Is there a tool for doing that?
fyi: I have a windows cmd line tool for doing this, but I'd rather work in linux.
Thanks Greg -- Greg Freemyer
