scheduling a shell script

[Shivkumar]

Dear Sirs,

i want to schedule a shell script jasmine.sh to execute every day at a particular time but don't want to put it in cron job. i want to execute as a login account on mine i.e. as a non-root user.

how can i achieve this ?

thanks,
shiv

Dear Shiv,

you can add the entry in the crontab, ( in the command field)

su - -c

now, in the sheduled intervals , the script will be executed as the specified in the above command ( and not as root). You can specify your username and your script.

With Regards,

Siva.

You can use at:

echo "/full_path/script.sh" | at 0200 tomorrow

Just add that line to the end of your script and it will repeat every day.

You can use cron to schedule jobs for users other than root.

First the user must be allowed to use cron. Add the user to /var/adm/cron/cron.allow

Then the user can edit his/her crontab with the 'crontab -e' command. Or root can edit another users crontab via 'crontab -e username'.

When the jobs run they will be run as that user.

Pete has just given the best idea.

The use of echo "/$PATH/filename" | at tomorrow

apologies, you must be permitted to use "at" on the server for this.

let sysadm add your name to at.allow

HP SIM can do this for you. (I am talking SIM 5, not the older revs. I also don't know if you have it installed or are familiar with it.)

I use HP SIM to login and run commands for me regularly, and it has a 'run now' option, and a 'schedule' option.

Short of running cron or some other scheduler, this is likely your best (free) bet. SIM is normally used for monitoring, but I use it for sysadmin tasks much more than monitoring.

Hope it helps

Hi Shiv,

"at" is the command to help you.

hi,

i usually prefer:

20 09 * * * echo "/prod/myscripts/jasmine.sh"|su - shiv 1>/prod/script/logfiles/output-jasmine.crn 2>/prod/script/logfiles/error-jasmine.crn

using cron of course

hope this helps!

kind regards

Hi shiva,
you can use both "at" and cron jobs to do it.
