crontab behaviour

[Spark_2]

Hi,

cron with entry:

0 18 * * 6 sh

is being executed daily...what could be the reason please

[Hasan Atasoy]

did you edit crontab file directly. or by crontab -e ?.
try stop and start cron deamon.

Hi,

>>what could be the reason
You are wrong your cron entry will not run daily as per your entry it will run
0 min 18 hr. but every 6 day of week.

In crontab file there are five fields

field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or names, see below)
day of week 0-7 (0 or 7 is Sun, or use names)

This should only work on Sat at 18:00.
I assume you have something other than just "sh" as the command?

[Spark_2]

Yes Dennis...sh has a command further...but it has been executing for last two days...

[Pete Randall]

What does /var/adm/cron/log show concerning this particular job?


Pete

[Spark_2]

it gets executed at the mentioned everyday since 2 days...I have checked the logs well

> 0 18 * * 6 sh

Where did you get this? Did you type "crontab -l"?

Run crontab -l and check if there is another cron entry for the same "sh" script.

Check what the sh script does when it runs. It could be scheduling itself to run again in 24 hours.

[Spark_2]

have already checked above mentioned two points...
