We did just do this, and *that* answer is wrong for system V braindamaged cron's that OR together the dow and day fields, rather than AND-ing them together as it has been done for all eternity before some stupid person (at AT&T?) got ahold of it again and attempted to "improve" the code. Don't start the discussion again, folks. -- /=Randal L.

Just run a little wrapper (a shell script would do) every night that
has your own rules for whether or not the real program should run
today. Here's a start (very generic, SYSV date can simplify this of
course):
#!/bin/sh
DOW=`date|awk '{ print $1 }`
DOM=`date|awk '{ print $3 }`
if [ "$DOW" = "Sat" -a "$DOM" -le "7" ]
then
DOIT
else
exit 0
fi
something like that anyhow, -le 7 is probably faulty, but that's not
the point, this is advice, not custom programming.
