如何從Perl作爲一個單獨的過程啓動程序？

可能重複：
How can I fire and forget a process in Perl?如何從Perl作爲一個單獨的過程啓動程序？

我正在尋找一種方式來從Perl腳本調用一個新的進程，這將讓啓動的程序和Perl腳本，從它已啓動，並行工作。如果它很重要，程序是SIPp。

謝謝。

如果你真的想分開過程，那麼另一種選擇是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; 
}
