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)
