Cron Job time and date settings

[progwihz@yahoo.com]

Hi All,

 

Am trying to schedule some cron job tasks and am alightly confused with the right date and time settings for the following scenarios

 

(1) Run a php file every week on a sunday at 9AM

1 9 * * 7

 

(2) Run a php file every two weeks on a monday at 11AM

2 11 * * 1

 

Am i right with the above settings? If not can anyone please correct me.

 

Cheers

Hope this helps:

 

*    *  *  *    *  command to be executed

-    -    -    -    -

|    |    |    |    |

|    |    |    |    +----- day of week (0 - 6) (Sunday=0)

|    |    |    +------- month (1 - 12)

|    |    +--------- day of month (1 - 31)

|    +----------- hour (0 - 23)

+------------- min (0 - 59)

 

Yours should be

 

0 9 * * 0

 

and I dont know how you would do the second one!

Cron doesn't have an option of every other day of the week, at least, not that I know of.  But you can test to see if the cronjob was run last week via a small bash script:

 

if test -f /dir/lastweek
then
       rm /dir/lastweek
       exit
fi
touch /dir/lastweek
run the job
