Subject: [CentOS] good shell script examples?
I am looking for a beginner guide to shell scripting simple tasks on CentOS (e.g. ssh'ing into a server / router / switch, checking for certain things, then exiting and going to the next IP).
Does anyone have any suggestions on where to look? ?(I'm relatively new to bash)

Or have a look at Fabric [1] which deals with SSH, sudo, passwords, etc. and multiple hosts so it would be a matter of:
@hosts('192.168.1.1', '192.168.1.2', '192.168.1.3', '192.168.1.4') def some_task(): put('rootidfile', '~/.ssh/authorized_keys')
and run it as:
$ fab -U root some_task
