Shalom,

crontab -e

man crontab


example

00 8 * * 1-5 /usr/contrib/bin/block-crawlers > /dev/null

At 12:08 a.m. Monday through Friday run the script /usr/contrib/bin/block-crawlers directing the output to /dev/null

Post your cron definition. Check the user's mail, cron will report errors by mail.

Ensure you use absolute paths for commands and scripts.

I see in your profile:

Please take a time to assign points to the answers you get, is a good way to thank for the support. See:

This isn't precise. You need to think in terms of a 24 hour clock. Do you want it at 0000 (midnight) or 1200 (noon) or both?

Hi,

crontab -l for listing
crontab -e for editing
crontab -r for removeing

these are the crontab fields
do crontab -e and set your program as per your plan

minute hour monthday month weekday command

* 0 * * * /home/abc/systemchk.sh (full path of command/program name)

Means every 00:00 hour this program will run
