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

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

The rule would be:

0 19 * * 1,3,5

I suggest that you use http://corntab.com for having a very convenient GUI to create your rules in the future :)

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

Use this command to add job

crontab -e

In this format:

0 19 * * 1,3,5 /path to your file/file.php

Have you tried the following expression ..?

0 19 * * 1,3,5

Use crontab to add job

  crontab -e

And job should be in this format:

  00 19 * * 1,3,5 /home/user/somejob.sh

Here's my example crontab I always use as a template:

    # Use the hash sign to prefix a comment
    # +---------------- minute (0 - 59)
    # |  +------------- hour (0 - 23)
    # |  |  +---------- day of month (1 - 31)
    # |  |  |  +------- month (1 - 12)
    # |  |  |  |  +---- day of week (0 - 7) (Sunday=0 or 7)
    # |  |  |  |  |
    # *  *  *  *  *  command to be executed
    #--------------------------------------------------------------------------

To run my cron job every Monday, Wednesady and Friday at 7:00PM, the result will be:

      0 19 * * 1,3,5 nohup /home/lathonez/script.sh > /tmp/script.log 2>&1

Use crontab to add job

0 0 9 ? * MON,WED,FRI *

The above expression will run the job at 9 am on every mon, wed and friday. You can validate this in : http://www.cronmaker.com/
