Run a shell script on multiple servers at the same time?
We have 15 servers. Hostnames for these 15 servers are stored in a text files and loop through each server to connect to the remote server and run a command, but this loop process runs the command one after another. However, the requirement is to run the same command on all 15 servers at the same time. We are connecting the remote servers using public/private key files.

Code:
textfile="/home/laknar/hostfile"

while read r
do
	ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no laknar@$r 'run a shell script'

done < $textfile

Any idea would be great.
