Script to check MD5SUM on file

Hi,

I currently have a shell script that takes an RPM and scp's it to a set of remote servers and installs it.

What I would like to be able to do is make the script get the md5sum of the RPM locally (so get the md5sum of the rpm from where im running the script) and then scp the rpm to the remote server, and then check the md5sum again, to ensure they match.

If the md5sums match, then continue, if they dont, cancel.

Anyone offer any pointers on how I can do this? Or an example script which I can ammend?

Thank you,

Tom
