in reply to Verifiying an external program exists

Try File::Tail. I don't know just what rkill does, but chances are there's a module for it. As a bonus, the script will (be easy to get to) work wherever these modules are installed, if that's a concern. (I always keep it in mind, if only fleetingly.)

Makeshifts last the longest.

    I can be sure that my coworkers all have 'tail' installed, but I can't ask them all to install File::Tail. But thanks for the idea.

    Cheers,
