How to launch program from Perl as a separate process?

Question

Possible Duplicate:
How can I fire and forget a process in Perl?

I'm looking for a way to invoke a new process from a Perl script, that will let a launched program and a Perl script, from which it's launched, proceed to work concurrently.

The program is SIPp, if it's important.

Thank you.

If you actually want separate processes, then another option is fork and exec.

if (fork) {
  # In the parent program
  # Continue as usual
  ...
} else {
  # In the new child program
  # Replace with another program
  exec $some_other_program;
}

SIPp has "-bg" commandline parameter.

This parameter launches SIPp in background mode.

In Windows system you may use "start" command.

For example:

start notepad

OR

start /d"C\Program Files\Sipp3.1" sipp.exe -sn uac
