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.

Kevin,


Don't know what is going on with your md5sum, but
I ran it on a LinuxPPC 2.2.17 System and a SunOS 5.6,
and got the same results ??????  The version of md5sum
on Linux was 1.22, and the version on Sun was 2.0.

Hi,

Here is what md5sum --version says on my machine.

[kbhend@localhost kbhend]$ md5sum --version
md5sum (GNU textutils) 2.0e

This appears to be newer that yours.  I will upgrade textutils again on both
my box and the solaris 7 box.  Hopefully eventually they will coincide.

I still don't know why MacOSX differs from both.  I thought it would match
one or the other so that I knew which one to upgrade.

Thanks,

Kevin

Hi,

I upgraded my Solaris 7 to the gnu 2.0 version and now it matches ppc linux
completely.

That still leaves MacOSX out in the cold but...

Thanks for the hint.
