Hi,

please can someone point me in the right direction with a shell scripting problem.
I want to execute a command in a for loop and the command should be started not one-by-one meaning the for loop is waiting for the exit code , it should be started in parallel.

I have a plain text file where a hostname stands in each line.

#!/bin/bash

file="/tmp/serverlist"

for server in `cat $file` ; do

ssh admin@$server "command to run"

done

the problem is :

the command I execute with SSH takes approx. 10 minutes to complete.

I have to run the command on 145 servers and I dont want to wait 10 mins to go to the next. I want to execute it in parallel say on 10 servers at a time.

Any ideas ? simply putting a & after the SSH commands didnt work, nor with continue ?


thanks for your help again...
