Need to create a simple script using MD5, SSH...
Hi all, I am brand new to these forums and I am a brand new UNIX Administartor. Don't know any scripting yet 
, and would like to learn as my boss is slowly letting me understand everything about being a Sys/*Nix Admin. He created this script which I am trying to replicate because I lost it to the dreaded /tmp folder. It was like 20 lines long. It seemed crazy easy to him 
. Oh well!
On to the problem...
I have a generated Directory Sync Report list of files that need to be synced across all servers/hosts (HP-UX ones). They are all supposed to be properly updated from the server which we push all the changes from, to all the other mirrors!
I have to use MD5 and SSH and SCP to do this. I have a script that generates hostnames/server-names (hostname.sh) which I am to use. My script should read the output of the file list (I think it was using SCP to get the files over from the other servers, and check the MD5 hash of each file, use SSH to check the same files across the other servers!
I REALIZE THIS MAY SEEM LIKE A HOMEWORK QUESTION BUT BELIEVE ME IT IS WORK RELATED.
AGAIN, I NEVER MADE A SCRIPT BEFORE!
I just need to be pointed in the right direction so that I can learn how to script myself these little things which come so easily to more experienced people!
Thanks a lot for any input!

I have a script that runs the grub-md5-crypt command based on whether the pass_value variable is a non-zero string. The md5 hash is being created in the /opt/hostconfigs/$HOST file, but I can't echo $md5_value. It is blank. Is there a way to create and echo a md5 hash variable?

check-hostname
check-hostname(1M) System Administration Commands check-hostname(1M) NAME
check-hostname - check if sendmail can determine the system's fully-qualified host name SYNOPSIS
/usr/sbin/check-hostname DESCRIPTION
The check-hostname script is a migration aid for sendmail(1M). This script tries to determine the local host's fully-qualified host name (FQHN) in a manner similar to sendmail(1M). If check-hostname is able to determine the FQHN of the local host, it reports success. Other- wise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined.

/etc/hosts Host name database /etc/nsswitch.conf Name service switch configuration file /etc/resolv.conf Configuration file for name server routines ATTRIBUTES
