Hello techman2006,

Please provide us with more information, what commands you want to execute, do you require root permission etc.

Recently there was similar question to yours Net::SSH2 to capture multiple commands on remote system where I am sure that you can find the answer. I have posted an answer exactly on what you want on this question.

Update: Based on the answer given by NetWallah about parallel ssh, I remembered that I read somewhere for a module in Perl, while I was trying to complete my task. Here it is Net::OpenSSH::Parallel, search of the web there are tones of modules with ssh that can do your task. I chosen to use Net::OpenSSH because I needed to execute root commands, in this case it was perfect to me.

Update 2: When I had trouble with the same task as you, I created a question Best module to execute administrator commands on external operating systems (Linux) at which you can find 3 different working answers to your problem with multiple devices.
