[re]verify those burned CD's early and often - better safe than sorry - at a bare minimum you need the good old `dd` and `md5sum` commands, but why not throw in a super "user-friendly" progress gauge with the `pv` command - adjust the ``-s'' "size" argument to your needs - 700 MB in this case, and capture that checksum in a "test.md5" file with `tee` - just in-case for near-future reference. *uber-bonus* ability - positively identify those unlabeled mystery discs - for extra credit, what disc was used for this sample output?
