no shell invoked in crontab
Hi all,

I am trying to run a script in crontab but I receive the email below. Note the empty variable SHELL. Apparently cron doesn't invoke a shell. That explains the errors in the script it is trying to execute. Anyone know what maybe wrong?


Subject: Output from cron job /vp1_ftp/prd/dba/dbm/scripts/cr_sp_snap.sh db1, ivanushka@db1, exit status 0

Cron Environment:

SHELL =
PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java14/jre/bin:/usr/java14/bin:/usr/java131/jre/bin:/usr/java131/bin
CRONDIR=/var/spool/cron/crontabs
ATDIR=/var/spool/cron/atjobs
LOGNAME=/vp1_ftp
HOME=/vp1_ftp/itgadba/ivanushka

Your "cron" job executed on db1 on Thu Oct 26 09:05:00 MESZ 2006

/vp1_ftp/prd/dba/dbm/scripts/cr_sp_snap.sh db1
produced the following output:

Here is the criontab entry

# statspack snapshots

The script runs perfectly from my home directory (or any other shell/ directory)

How do you know that cron is not invoking a shell? What do you think is reporting the errors that you have presented?

Read this post and especially look at the section titled "It works from the command line but not in crontab."
