如何从Perl作为一个单独的过程启动程序？

可能重复：
How can I fire and forget a process in Perl?如何从Perl作为一个单独的过程启动程序？

我正在寻找一种方式来从Perl脚本调用一个新的进程，这将让启动的程序和Perl脚本，从它已启动，并行工作。如果它很重要，程序是SIPp。

谢谢。

如果你真的想分开过程，那么另一种选择是fork和exec。

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