You can not. You must put these checks into the script, since cron only ORs specs like that.

Add this near the top of your script:

# Check 2 & 3 Sat

set -A dates $(date +"%e %w")
#echo "Day, weekday: ${dates[0]}:${dates[1]}"

if (( ${dates[1]} == 6 && ${dates[0]} >= 8 && ${dates[0]} <= 21 )); then
echo "Skipping second and third Saturdays"
exit 0
fi

Hi,

- As per 1st & 3rd saturday to skip , per Dennis's script : you can use like below, in your script at the begining:

-Nothing can be done in the crontab entries.

Add this near the top of your script:

-----------

# Check 1st & 3rd Satday to skip.

set -A dates $(date +"%e %w")
#echo "Day, weekday: ${dates[0]}:${dates[1]}"

# For 1st Saturday.
if (( ${dates[1]} == 6 && ${dates[0]} >= 1 && ${dates[0]} <=7 )); then
echo "Skipping First Saturdays"

exit 0

# For 3rd Saturday:

if (( ${dates[1]} == 6 && ${dates[0]} >= 15 && ${dates[0]} <=21 )); then
echo "Skipping Third Saturdays"

exit 0

# End 1st/3rd satday skip check function.

-------------

Hth,
