Hi,

This query belongs to an Unix forum.

You may use cron, unix task scheduler to execute predetermine jobs at timely intervals.

crontab -l
will list your current active cron table entries.

crontab -e
will get you directly into edit mode

A crontab input has six fields:
minute (0-59)
hour (0-23)
day of month (1-31)
month of year (1-12)
day of week (0-6, 0 is Sunday)
Command

Example:
0 18 1 * 0 date | mail user
will execute at 6 p.m. on the first of each month as well as at 6 p.m. on every Sunday.

Typically your cammand file will be a script, containing the set of instructions. Command file should specified with full path in crontab specification.

Regards,
Shriyan

Hi,

This is a cron entry to run this script every Monday morning at 8:00:
0 8 * * /u1/rmlivetemp.sh

contents of /u1/rmlivetemp.sh
rm -f /u1/live/spool/livetemp*

or

the cron entry could be:
0 8 * * rm -f /u1/live/spool/livetemp*

Shriyan

pctekk:

As an user you can list your current active cron table entries using:
crontab -l

if you have already one, and to go directly into edit mode, or start a new entry entry for crontab file using:
crontab -e

The default editor is "vi" for editing/adding an entry. For futher help look at mannual pages:
man cron
man crontab

at your operating system prompt. By the way, this site hosts some Unix forums:
forum80
forum822

pctekk,

The list seems to be crontab entries that belong to the superuser (root) of your unix box. It's alright. Do not alter these entries unless you know exactly what you are doing!

You may append a line in this file if you wish, for your activity of cleaning up of /u1/live/spool/livetemp* or you may login as other authorised user and create/add crontab entry of your own apart from a root user.
