cron scheduling

[Noelle Stimely_1]

Hello..

I was wondering how to schedule a cron job to take place on an hourly basis? I greatly appreciate your help!!

Thank you...

00 * * * * command

put this in a file
crontab filename
to set it up under cron
crontab -l
lists cronjobs
man crontab will list the fields

Enter crontab -e to properly vi the crontab file. Then...

00 0-23 * * * command string

That should take care of hourly scheduling

Good Luck

Hi Noelle,

To run a job hourly try this command in your crontab file. If you don't have a crontab file, create one using crontab -e. To check your current crontab file do, crontab -l. Edit this file and put and entry in it as shown below to run the job each hour, every day, throughout the year. Do a man crontab for more info and to create your custom cron job.

00 x x x x /path_to_the_job

Hope this helps.

Hi,

00 * * * * would work. See man pages of crontab for more detailed examples.

crontab -e #edit the crontab file
G #go to bottom of file
o #add line blow
00 * * * * /your/script/to/run/on/hour #your entry
:wq!

Will run the script on the hour.

Hope this helps.

crontab file is like this
Minute Hour dayOfMonth Month Dayofweek

so to run a job every hour on the hour..
0 * * * * /jobs/to/run

Hi Noelle:

In addition to the information you already have, note this from the 'crontab' man page:

"You can execute crontab if your name appears in the file /var/adm/cron/cron.allow. If that file does not exist, you can use crontab if your name does not appear in the file /var/adm/cron/cron.deny. If only cron.deny exists and is empty, all users can use crontab. If neither file exists, only the root user can use crontab."

Similar security also exists for 'at' commands using the /var/adm/cron/at.allow and /var/adm/cron.at.deny files.

Regards!

Hi,

When editing the crontab make a habit of *not*
using the -e switch. Make a copy to a temporary
file and then submit it.

# crontab -l >/tmp/wrk
# vi /tmp/wrk
Make your changes (for example)

0 * * * * /usr/local/bin/my_job.sh

Save the file
# Submit it to cron
# crontab /tmp/wrk
