Issue
I am using Bash on RedHat. I need to schedule a cron job to run at at 9:00 AM on first Sunday of every month. How can I do this?
Solution
You can put something like this in the crontab
file:
00 09 * * 7 [ $(date +\%d) -le 07 ] && /run/your/script
The date +%d
gives you the number of the current day, and then you can check if the day is less than or equal to 7. If it is, run your command.
If you run this script only on Sundays, it should mean that it runs only on the first Sunday of the month.
Remember that in the crontab
file, the formatting options for the date
command should be escaped.
