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

grid-ca-package

GRID-CA-PACKAGE(1)						  Globus Commands						GRID-CA-PACKAGE(1)

NAME

       grid-ca-package - Prepare a CA certificate, configuration, and policy for distribution

SYNOPSIS

       grid-ca-package [-help] [-h] [-usage] [-version] [-versions]

       grid-ca-package [-ca HASH] [-g] [-b] [-r] [-d]

DESCRIPTION

       The grid-ca-package utility creates a tarball containing an RPM spec file and the files needed to use a CA with grid tools. It optionally
       will also create a GPT package for distributing a CA.

       By default, the grid-ca-package utility displays a list of installed grid CA and prompts for which CA to package. It then creates a tarball
       containing the CA certificate, signing policy, CA configuration files, and an spec script to generate a binary RPM package containing the
       CA. If the CA hash is known prior to running grid-ca-package, it may provided as an argument to the -ca parameter to avoid prompting.

       In addition to generating a spec script and tarball, grid-ca-package creates a GPT package if either the -g or -b options are used on the
       command-line. These packages may be used to distribute a CA and configuration to systems which do not support RPM packages.

       The grid-ca-package utility writes the package tarballs to the current working directory.

       The full set of command-line options to grid-ca-package follows.

       -help, -h, -usage
	   Display the command-line options to grid-ca-package and exit.

       -version, -versions
	   Display the version number of the grid-ca-package command. The second form includes more details.

       -ca CA
	   Use the CA whose name matches the hash string CA. When invoked with this option, grid-ca-package runs non-interactively.

       -g
	   Create a GPT binary package in addition to the RPM script tarball. This package may be installed on other systems using the gpt-install
	   program.

       -b
	   Create a GPT binary package with GPT metadata located in the path expected by GPT 3.2 (used in Globus 2.0.0-5.0.x) instead of
	   ${datadir}/globus/packages as used in Globus 5.2.x. This option overrides the -g command-line option.

       -r
	   Create a binary RPM package for the CA. This option currently only works on RPM-based distributions.

       -d
	   Create a binary Debian package for the CA. This option currently only works on Debian-based distributions.

EXAMPLES

       Package a Simple CA with hash 0146c503

	   % grid-ca-package -ca 0146c503
	   Creating RPM source tarball... done
	     globus_simple_ca_0146c503.tar.gz

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of grid-ca-package:

       GLOBUS_LOCATION
	   Non-standard installation path of the Globus toolkit.
