Good point Jim. I was only looking within the scope of a single month. You're right, there is no way to do this with-in cron. Smilie

It is not possible to provide crontab parameters to execute a cron every other Friday. It is possible to make a process run under cron every other Friday.

You could achieve the effect with an "at" job which starts by issuing another "at" job for two weeks hence before continuing execution.
There is an example in Hp-UX "man at" for issuing an "at" job for a specific time one week from next Tuesday. Try it before relying on it.

It is quite easy to write a wrapper script to run weekly from cron which detects the age of a marker file and updates the timestamp on such a marker file. This sort of process will need seeding with a file created with "touch" on the first iteration.
