Hi ,
Normally bash is interactive environment.
But cron is not.
You may need to redirect output of your script
to somewhere for example
You can add >/dev/null 1>&2 en of your cronjob.
Hope it helps.

Is there something different about running a job in cron then there is

This program is starting several other programs (If that makes any
difference.)

Terry,

Does your program require environment variables to be set before running
the program itself?

By default cron does not create an user environment.

To set an user environment I use a script,say cron-pascal-program.sh
with a content like:

su - user -c /path/your-FreePascal-program

and the cron entry like:

0 0 * * * /path-to/cron-pascal-program.sh

Other option, I have not tested: cron entry

0 0 * * * /bin/su - user -c /path/your-FreePascal-program

This way your user environment is set at runtime of the Pascal program.

Best regards,

Jan Gerrit Kootstra



Botsali,


You do not need to redirect the output, it will be mailed to the user owning the crontab.

It is good practise to redirect I agree, but it is not needed.


Kind regards,
