Hi,

I want to run a crontab job but it isnt working. I am writing in the crontab file with crontab -e Then I am waiting time but it isnt working.

Code:

15 17  * * * ./home/admin/backup_sc

Command running on the terminal window When I try to run this command (./home/admin/backup_sc) and I see it is running but it isnt working when I write to crontab file.

you can see crontab file at below.

Why it isnt running?

15 17 * * * ./home/admin/backup_sc

Hi,

It probably is running (trying to run, to be more specific).

Crontab doesn't have a full set of environment settings (opposed to a "normal" shell). If your script relies on any environment setting, it probably won't run from cron.

Post your script so we at LQ can have a look and point you in the right direction.

"./home/admin", you're using a relative path, which is a really daft idea, and secondly you're assuming this relative position is "/" Which is never going to be the case. I *think* you just didn't want to put the . there in the first place.

@epamuk: Try acid_kewpie's suggestion first, it is more probable then my suggestion (I missed it to be honest...).

Hi acid_kewpie and druuna,

We try as /sbin/backup_sc but it isnt still working.

you can see crontab details and you can see script content.

I didnt understand, why this crontab isnt working?

Code:

[Expert@test_cpng]# crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.5256 installed on Tue Feb  2 17:45:07 2010)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
20 8 * * * /sbin/backup_sc

Code:

[Expert@test_cpng]# cat /sbin/backup_sc 
st=/opt/CPshrd-R70/bin/cpstop
CMD=/opt/CPsuite-R70/fw1/bin/upgrade_tools/upgrade_export
BKPDIR=/var/fwbackup/
FILE="FW-`/bin/date '+%d-%m-%Y'`_ogle"
$st 
echo "\n" | $CMD ${BKPDIR}${FILE}
/opt/CPshrd-R70/bin/cpstart

Code:

[Expert@test_cpng]# ls -al backup_sc
-rwxrwx---    1 root     root          216 Feb  1 17:19 backup_sc

script file under the /sbin folder.

cronjob scheduled for 08:20 every morning...

Can you check root's mail?

cron will send a mail to root containing output from root's cron jobs (including STDERR messages). This will most likely help with troubleshooting the problem.

well you're not running it as root, which seems odd. Backups are system level operations, therefore should be executed at that level, via the /etc/crontab not by a user accounts crontab. Does this other user have rights to put files there?
