Timeout on a script or program in Linux is easy!
Did you ever have the need to kill a process if it takes too long to run for any reason? Then this post will show you how you do just that.

This could be used to prevent a cronjob for running too long or prevent cronjobs from overlapping if a lock-file is not the optimal solution in your case.
It could also be used in a case where a process freezes for unknown reasons, and you need to force a restart of it based on a how long it has been running for.

This is not just useful for cronjobs, it can set a timeout on any process, script or program you run!
