Message: [QUOTE="Yukihiro Matsumoto, post: 4450791"] Hi, In message "Re: process fire and forget?" |Is there a ruby way of firing up a process and then |forget about it? --------------------------------------------------------- Process#detach Process.detach(pid) => thread ------------------------------------------------------------------------ Some operating systems retain the status of terminated child processes until the parent collects that status (normally using some variant of +wait()+. If the parent never collects this status, the child stays around as a _zombie_ process. +Process::detach+ prevents this by setting up a separate Ruby thread whose sole job is to reap the status of the process _pid_ when it terminates. Use +detach+ only when you do not intent to explicitly wait for the child to terminate. +detach+ only checks the status periodically (currently once each second). [/QUOTE]
