so i want to write a perl script Sure, go for it, I give you permission. Was there anything else you wanted? To put it another way: where are you having a problem? What have you tried already and how did it fail? The more effort you put into your question the better the help you will get. As a general thing we don't do your work for you, but we often go to extraordinary lengths to help you understand how to do things for yourself - give us that chance.

I need to delete multiple clients using command: p4 client -d <client-name> Please see my node Calling External Commands More Safely for example code on how to do this. In this case, I might suggest IPC::Run3.	[reply]

Seems more like a shell script. If you want to use Perl, then you can do it using any number ways for Perl to generate child processes. Based on your description I recommend system or if you have multiple CPUs (or vCPUs), use fork via something like Parallel::ForkManager. I am assuming non-Windows, is that okay? :D	[reply]
