[ale] cron entry that runs the 2nd saturday of every month

[Lightner, Jeff]

But the OP wanted 2nd Saturday only.  The +%u just tells you it is Saturday - not which Saturday.

I had tested for it being Saturday in my 2008 script but if the cron job only runs on Saturday it isn't really necessary.   (My test was to prevent someone from just moving the cron job without understanding its purpose.)

Doing something similar only relying on date alone:

date +%d
date +%u
