Hi, There's no way to accomplish this via crontab itself. You'll need a little help by means of a script. This works: 1) create the following script. Let's call it tuesday-check.sh: #/bin/sh [ `date +%m` -ne `date -d "+7 days" +%m` ] && your-actual-command.sh 2) create a crontab entry for the above script so that it runs every Tuesday (yes I know you want the last Tuesday; the script will precisely check that): 15 18 * * 2 /root/bin/tuesday-check.sh Explanation: date +%m ...returns the *month number* for today date -d "+7 days" +%m ...returns the "month number" for this day *one week ahead* For example, if I were to run this on the last Saturday of the month (today the 28th): - the first command would return "7". - the second command would return "8" because the NEXT Saturday is already August. Because both of the returned numbers are different (7 and 8) the command will run.
