Hi,

Just to have a bit of fun, how about this (3 different systems)
Each generates a different md5sum but all generate the same cksum!
(and adding -b to md5sum makes no difference)

I guess md5sum is not a very reliable or consistent checksum measure for moving
files between ppc linux, MacOSX, and Solaris 7 Sparc.

Back to the old cksum for me.
