Script to check MD5SUM of 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

NAME
md5sum - compute and check MD5 message digest SYNOPSIS
md5sum [OPTION]... [FILE]... DESCRIPTION
Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is -, read standard input. -b, --binary read in binary mode -c, --check read MD5 sums from the FILEs and check them --tag create a BSD-style checksum -t, --text read in text mode (default) The following five options are useful only when verifying checksums: --ignore-missing don't fail or report status for missing files --quiet don't print OK for each successfully verified file --status don't output anything, status code shows success --strict exit non-zero for improperly formatted checksum lines -w, --warn warn about improperly formatted checksum lines --help display this help and exit --version output version information and exit The sums are computed as described in RFC 1321. When checking, the input should be a former output of this program. The default mode is to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE. BUGS
Do not use the MD5 algorithm for security related purposes. Instead, use an SHA-2 algorithm, implemented in the programs sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1), or the BLAKE2 algorithm, implemented in b2sum(1) AUTHOR
