Question ID: 161912

I need a perl script (which, fyi, will be run as root as a cron job).

The script takes 2 arguments, "scriptname" and "age" (in seconds).

When invoked it does the following:

1. Check for processes that are running as instantiations of a perl
script called "scriptname" (there may be more than one such process).

2. Check each such found process to see if it has been running for
more than "age" seconds. If so, kill the process.

Thanks for helping.

Marc.
