Crontab probelm

[Sameer S]

Hi frens,

I am facing some problem in executing crontab.
When I put a shell script i have written in crontab or even try executing it using a"at", it is not executing. But if I try executing it directly, it works.
Does somebody have a solution ???

Hi

You can execute crontab if your name appears in the file
/var/adm/cron/cron.allow. If that file does not exist, you can use
crontab if your name does not appear in the file
/var/adm/cron/cron.deny. If only cron.deny exists and is empty, all

Hewlett-Packard Company - 2 - HP-UX Release 10.20: July 1996

crontab(1) crontab(1)

users can use crontab. If neither file exists, only the root user can
use crontab.

You can look for the error in /var/adm/cron/log file
and i guess you are giving the complete path of the file you are executing using cron.

Hi

if you execute a shell-script with cron/at the /etc/profile and $HOME/.profile are not sourced, so cronjobs have an other environment.

To be sure to have the correct environment you have to do something like that:
0 0 * * * (. /etc/profile; . ./.profile;
If you are using c-shell you have to source /etc/csh.login, $HOME/.cshrc and maybe $HOME/.login

I have had problems like that
Restarting the cron daemon does solve the problem

Hi,

These are usually caused by environment issues. Check out:

Also check the special char being used. Like date +%a will work fine when you execute in shell but will not work in crontab. you will need to give escape char before %. (date +\%a)

So if you are passing any option to your script in cron then escape it...

hope this helps...

Hi!
In addition - do you ensure the correct output
for your script in crontab:
00 10 * * *

If you are using HP-UX 11.0 you may need to apply a cron patch. See this posting...

hi,

try to run it by doing a su!


e.g. Root's cron and "yd" is the user using which the shell script works (directly)!


5 13 * * 1 echo "/home/yd/myscript.sh"|su - yd 1>/home/yd/output-myscript.crn 2>/home/yd/error-
myscript.crn
#*******************************************************************************
# min|hour |day |month|day |script
# | |of mo| |of wk|
#----|-----|-----|-----|-----|--------------------------------------------------
#*******************************************************************************
#*******************************************************************************
# END OF TABLE day0->Sunday day6->Saturday
#*******************************************************************************

The .crn files will help you troubleshoot any further errors.

Hope this helps!

Best Regards
