What Ramon correctly explained to you, if you want a simple cron job, say which runs every week, then copy your perl script in the directory /etc/cron.weekly.
So you do: $> cp /my/sexy/antivirus/script /etc/cron.weekly and then leave linux do the job. Simple as that. Ah...and just to know the meaning of plonk: plonk v. & n. & adv. Variant of plunk. plunk v. plunked, also plonked plunk*ing, plonk*ing plunks, plonks v. tr. To throw or place heavily or abruptly: plunked the money down on the counter. To strum or pluck (a stringed instrument). In terms of the previous post, I must presume that it means "put the script in the cront.weekly directory.
