如何从 Perl 启动程序作为一个单独的进程? [英] How to launch program from Perl as a separate process?

问题描述

可能的重复:
如何在 Perl 中触发并忘记进程?

我正在寻找一种从 Perl 脚本调用新进程的方法，这将使启动的程序和从中启动的 Perl 脚本同时工作.

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.

该计划是 SIPp，如果它很重要.

The program is SIPp, if it's important.

谢谢.

推荐答案

如果你真的想要单独的进程，那么另一个选择是 fork 和 exec.

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;
}
