I want to create a daemon
that runs two perl programs that I have made, but not
Use fork to create new processes.
if the programs is running one of the other programs schould be check every 5 min and the other schould be check every 15 min. and
Several options, depending on how sure you want to be. One simple way is for the child process to save it's PID in a known location such as /var/run and delete as it exits. The parent can check for the known files before starting the child.
Use sleep or e.g. Sys::AlarmCall to set timers.
I want the daemon to run as xxdaemon not perl ./daemon.pl
Rename daemon.pl as xxdaemon, make it executable and make sure it has a shebang line.
