How to run a cron job on every Monday, Wednesday and Friday?

Question

How can one run a cron job for every Monday, Wednesday and Friday at 7:00 pm?

Answer 1

This is how I configure it on my server:

0  19  *  *  1,3,5 root bash /home/divo/data/support_files/support_files_inc_backup.sh

The above command will run my script at 19:00 on Monday, Wednesday, and Friday.

NB: For cron entries for day of the week (dow)

0 = Sunday
1 = Monday
2 = Tuesday
3 = Wednesday
4 = Thursday
5 = Friday
6 = Saturday
