Problem with crontab

apapa · 10-18-2010, 03:19 AM

Hello everyone,

Could you please help me with the following?
I have a cron running the third week of each month and more specific the third Tuesday.

00 21 15-21 * 2 /home/path/script.sh

Suddenly, this month it run on Sunday night! Does anyone knows why that happened?

Thank you in advance!

Well, 2 is definitely Tuesday, so if it ran on a Sunday, you've got another copy somewhere...

I think the way you have it, your script will run on days 15,16,17,18,19,20,21 AND every Tuesday. How many months have you had your script running for?

Thank you for your response!

I cannot understand... I may have another copy of cron? I cannot see anything with crontab -l command.

This script is running correctly for four months... until now of course!

It is running once every month, between 15-21 when the day is Tuerday.

Thank you again!

Nope. As bulls_i3 already noticed, the job should have been executed every day between 15th and 21th plus every Tuesday. As explained in the crontab man page:

Quote:

Note: The day of a command's execution can be specified by two fields —
day of month, and day of week. If both fields are restricted (ie, aren't *),
the command will be run when either field matches the current time. For example,
"30 4 1,15 * 5" would cause a command to be run at 4:30 am on the 1st and 15th
of each month, plus every Friday.

Which version of cron have you on your system, anyway?
