Crontasks for root user not completing although tasks are executed

Kripal_1 — Tue, 26 Oct 2004 03:10:57 GMT

Hi,
Some crontasks (only for root user) are failing with return code rc=1 in our system. (I could see this from cron log)
I modified crontab and removed redirection from tasks so that errors encountered while executing that task could
be sent as a message (mail) to the administrator. (read from 'mailx' using root# mailx) but unfortunately the mail
messages are not coming.
~~~~

50,54,58 * * * * csh -c 'nice $ROOT_HOME/lib/script/testscript.sh'

==> removed > /dev/null 2>&1 from the task
~~~~
I want to check the status of execution the crontasks to investigate why the tasks are not completing although the commands are executed by cron. Is there any other way out ???

I tried modifying crontab by redirecting the command stdout to some temp file :-
~~~~

50,54,58 * * * * csh -c 'nice $ROOT_HOME/lib/script/testscript.sh'> /tmp/testscriptlog.txt
~~~~

but it did not work only the file is created in /tmp, the error is not logged in the file.
kindly help with your suggestions.

You must also redirect STDERR. This could be done with
... > /tmp/testscriptlog.txt 2>&1

Hi,
try this csh redirection:

50,54,58 * * * * csh -c 'nice $ROOT_HOME/lib/script/testscript.sh' >&/tmp/testscriptlog.txt

but perhaps you should try first to only execute your program at 50 minutes; perhaps it has not finished before 54 - which could cause the problem.
