Writing Daemons in Perl
Webreference.com has a excelent tutorial on writing Unix Daemons in Perl.
In Unix, daemons are typically started by the root process when the operating system is initialized, and run in the background indefinitely. Daemons typically spend most of their time waiting for an event or period when they will perform some task. (….) In this tutorial, we’ll learn how easy it is to turn a Perl script into a daemon process.
Its been around for a while, but it would appear that I neglected to blog it when I first saw it. Now that I’ve needed the info, I figured I’d better save it for future reference.

The article isn’t very helpful in practice. I’ve written a daemon using it that crashes left and right because it doesn’t correctly handle the fork() methods, and because there is no decent signal trapping and file descriptor handling in that article. I’ve taken a completely different approach based on other sites I found that make use of sigtrap and the system’s select() calls instead of fork() and my daemon is now rock-solid. Good luck. =)
