I have written some scripts that do a few admin tasks on 23 servers I manage.
Usually I execute these scripts from one server by running ssh commands remotley, i.e.
ssh root@server2 shellscript, ssh root@server2 shellscript & so on..

It works fine but I want to improve this by writing a script on my main server to run all the scripts on the other 23 servers.

Opinions on whether this is a good idea or not would be great & advice on how to implement it effectively would be great.

While I see where your going with this, IMHO I would not. I would run the commands separately, if you messup 1 server with a bad script its eaiser to fix then running one command and killing all 23 or however many.

if you want to do it I would guess one way would be to create an array with all the servernames. then do a for each server in the array and call the commands/script.

In the past I had somethign similar for updating linux workstations. I had a script on the remote workstations run a cron script that checked for an update on a web server. If it was "true" it would wget the script and run it. So there were no actual ssh'ing. The cron would run everyhour or how ever long you wanted.

Thanks for your input Ikon, you've given me some useful feedback, appreciate it.
