你如何在 Perl 中启动后台进程? [英] How do you start a background process in Perl?

问题描述

我想弄清楚如何在 perl 脚本中启动后台进程(在 Windows 上).换句话说，我不希望脚本在重新获得控制权之前等待子进程完成.有没有一种简单的方法可以在短短几行代码中做到这一点?我已经查看了系统命令的 perldoc，但它似乎没有做我想要的..

I'm trying to figure out how to start a background process in a perl script (on Windows). In other words, I don't want the script to wait for the child process to complete before regaining control. Is there an easy way to do this in just a few lines of code? I've looked at perldoc for the system command, but it doesn't seem to do what I want..

推荐答案

在 perlport 中查看系统:"system(1,@args) 产生一个外部进程并立即返回其进程指示符，而不等待它终止...(Win32)"

See system in perlport: "system(1,@args) spawns an external process and immediately returns its process designator, without waiting for it to terminate...(Win32)"
