Problem with crontab

jcgg · #1 (**permalink**) 10-31-2003

Hi guys!
I have a problem with my crontab. I made a script named expsa.sh, but I can not execute it on crontab:

00 11 * * * /sa/expsa.sh

The strange thing is that i can do it by using `at `:

at -m 1100
at> /sa/expsa.sh

it works!
What can i do for doing the first one?
Thanks. By

Just a couple ideas til someone with more knowledge of crontab helps you:

- is the "sa" directory located in root? Or is it actually something like /usr/local/sa/expsa.sh, for example?

- are the permissions correct on the file?

- are you receiving any sort of errors on screen, in a logfile, etc. How do you know it's not running, but just not producing any output?

I forgot write about errors.

Yes, sa is in root.
It shows an error: expsa.sh: exp: not found

The only thing I could find on that error was an old post in the IT Resource Center forums, and it looks like the only solution they came up with was that the OP should be using an absolute pathname instead of a relative one (e.g. /usr/local/someFile rather than just someFile), so I'm not sure what's wrong with the way you have it...

crons PATH env variable can be set in /etc/default/cron on solaris.

if you dont want to use absolute paths in your script, makesure you specify the PATH env variable in yoru script befor you run any commands.

From at(1)

Quote:

The first part sets up the environment to match the environment when the at or batch command was issued. This includes the current shell environment variables, current directory, umask, and ulimit.

And from crontab(1)

Quote:

cron supplies a default environment for every shell, defining:

HOME=user's-home-directory
LOGNAME=user's-login-id
PATH=/usr/bin:/usr/sbin:.
SHELL=/usr/bin/sh

Set your environment to match what cron will give you and then submit the at job. It will fail then.

Scripts that run from cron should not depend on the environment.
