It's a good idea. OSX has md5 and Linux has md5sum; I'm going to assume 
that they're the same tool with different names.

OSX output:
$ md5 rq.dsk
MD5 (rq.dsk) = f29cdac56ede456dcba7e30fc7d9dd6c
Linux output:
$ md5sum rq.dsk
f29cdac56ede456dcba7e30fc7d9dd6c  rq.dsk

The checksum appears to be the same in both.
