- Bispiel aus Crontab – Quick Reference
The day of month & day of week are ORed, which makes cron less flexible than it could be. I need to run a job on the 3rd Wednesday of every month, but cron won’t let me do this. I figured it out in the end; run every day in the 3rd week, but then check that the day is a Wednesday. e.g.
00 02 15-21 * * if [ `date +\%u` -eq 3 ] ; then run_myjob; fi
Note that the \ is used to escape the %, otherwise cron treats it as a newline.
