Normally no further explanation is needed; according to my experience 99 % of 'not working cron jobs' come from the fact that cron jobs have no correct environement set !! All settings from the shell (especially $PATH) are not know in a cron job. Specify a correct environement in your job and cron will work.

Make sure that your cronjob is listed with the command

crontab -l

It doesn't harm if you run this command

crontab -l > my_cron_file

crontab my_cron_file

Also you can check if the job ran or not in /var/adm/cron/log file

Hi Mark,

1.Ensure that there is something planned with crontab :
#crontab -l [UserName]
without username , stands for root.

2. Verify that the syntaxe is OK inside the crontab file :

minutes hour monthday month weekday command

minutes : 0-59
hour : 0-23
monthday : 1-31
month : 1-12
weekday : 0-6 ( 0 is sunday )

3. Ensure ( very important ) that the envirenment profile file for a specific user is executed at the begining of the crontab job :

. /home/users/.../.profile

4. Ensure that the process /usr/sbin/cron is running.

Hi again Mark,

The command in the crontab file, in my last post, should by in absolute path to avoid any miss of environment setting. Like :

examples :

0,30 12,17 * * * /home/users/checkSpace.sh

This command checks space all at :
- zero and 30 minutes ( You can add other minutes with comma separator ).
- 12 and 17 hour ( You can add other hours with comma separator ).
- All days in month ( * stand for all days, you still can add any days in month with comma separator).
- All months in year ( * stand for all months, you still can add any months in year with comma separator).
- All days in week( * stand for all days, you still can add any days in week with comma separator).
