Script to compare all the config files in a cluster of servers.
Hello Lads!
Climbing the shell scripting learning curve, i am faced with yet another obstacle! Here's the challenge in front of me :
1) I have 15 servers in a cluster,all of them have the same config files by name : /home/apps/xrm/App_B.cfg
2) The developers change the entries in the config files as and when required, and this is done on all the servers in the cluster.They take a backup of the original backup config before modifying it. Something like this: App_B.cfg.021509
3) I am trying to come up with a script which can be run on any one of the servers in the cluster which can do a comparision between the new config file (modified) and the old backup and put the result in a log, it should do this on all the 15 servers without me having to run the script on all boxes :
I know this must sound pretty silly for the experts here, but i am unable to come up with a solution with my very elementary scripting skills. Help would be greatly appreciated, and oh, the SSH keys are shared on all the servers,so thats not a problem. Thanks.
Thank you Sir ! It works well! Just that it ends up creating a logfile on all the boxes,which means i'll have to login to all 15 boxes in the cluster to check the diff results. Is it possible that all the results are put in just 1 logfile from where the script is being run? ( In our case,bpon03), with the server names appended above each diff result?
Thank you. I think thats a good idea,although it'll end up creating 15 logs on the server each time i run the script, but i should be able to live with that.

If you don't want 15 log files, redirect them all to one file, e.g.:
