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!
