What is the easiest way to run a shell script in the background on 10 servers?


What is the easiest way to run a shell script in the background on 10 servers?

I know you can do a for loop like:
for in server1 server2 ... server10; do `ssh -l root $i $cmd`; done;

but the script takes about a half hour to run, and the for loop won't go to the next server until one has finished.

Anyone know of a way to start the $cmd then go to the next server before it finishes?

You could try running each command in the background.

I tried cluster-ssh, dsh, and fanout

Couldn't get cluster-ssh to work via a remote connection to the terminal, dsh worked the same way as the for loop, and fanout worked perfectly:
