Dear Madhu

You must login as the root to run following commands. Each user that is using the cron service must have a cron configuration file in the /var/spool/cron/crontab directory. Also users are permitted if their name appeared in /var/adm/cron/cron.allow file

Task: Find out if cron is running under HP-UX
Type the following command at a shell prompt

# ps -ef | grep cron

Open /etc/rc.config.d/cron file

vi /etc/rc.config.d/cron

Set control variable to 1 to enable cron : CRON=1
Set control variable to 0 to disable : CRON=0
Close and save the file. To start or stop cron you can type the following command:

# /sbin/init.d/cron start <-- start cron
# /sbin/init.d/cron stop <-- stop cron

Task: HP-UX Start cron service
If cron is not running, simply type:

# cron

Task: Edit / create cron jobs
Type the following command to submit a cron job:

# crontab -e

List your cron file:

# crontab -l

Remove ALL cron job:

# crontab -r

thanks and regards

Hi Madhu,

A variable named CRON in the
/etc/rc.config.d/cron file controls whether the daemon will be started at boot time. If this variable value is
1, the daemon is started at boot time, and if the value is zero (0), the daemon is not started.

just edit the crontab file by
crontab -e command

And to start it /sbin/init.d/cron start command...

You can get the related script at /sbin/rc2.d/S730cron location...

Regards,
Aaryan
