issue with crontab job execution
 

Dear Friends

I'm having some issue when executing script via cron

the script run fine when i run it manually

./scriptname.sh & takes around 10min

but when it executed from cron seems it's not running properly.

We have echo like "job starting at " & "job ending at"
From the logfile I can see that the echo command is executed but
not other commands in between.

starting & ending time is same (or 1sec diff) but actually it should take 10min.

I'm not able to capture terminal message written by this script.

when run manually 'script' command work ( thogh no issue when run manually).

I can't include 'script' command in this script as I'm not able to pass ctrl+D/exit to terminate it.

The devloper who actually write this script ( with TGIT command) couldn't help me much.
(It's a housekeeping job)

Could someone please help me to find the possible cause of this ?
Is there any way to capture the terminal message in log file when the script run which possibly can help
to see errors? ( job run at midnight when no one available at office)


NB: when I run manually first time - it initially showing dir not found - though mentioned path inside script was correct.
Then I create new .sh script by vi & copy same commands again & then it execute in newly created script without any issue.not sure about the reason.

Are you using absolute paths for the script name in your cron entry?

se michaelk post but also add set -xvv at the top of your script and push the data to a log file so you can see exactly what is going on.

Further clarification

$crontab -l
10 01 * * * /scripts/git/repack.sh

where

cat /scripts/git/repack.sh

echo "starting script ... at `date` " >> /scripts/git/log/`date +20%y%m%d`_repack.log
cd /home/gitadmlocal/repositories/ILP/CoreProduct.git
< git command writed by developer -- which is not doing anything when run from cron>
echo "Ending script after running... at `date` " >> /scripts/git/log/`date +20%y%m%d`_repack.log


Housekeeping command working when run the script manually
./repack.sh

Are you trying to run a command or change directories? If the first then remove the cd.

/home/gitadmlocal/repositories/ILP/CoreProduct.git

Here is the complete script ( repack.sh)

echo "starting script ... at `date` " >> /scripts/git/log/`date +20%y%m%d`_repack.log
cd /home/gitadmlocal/repositories/ILP/CoreProduct.git
git repack -a -d -f --window-memory 200m --max-pack-size 200m --depth 50
echo "Ending script after running... at `date` " >> /scripts/git/log/`date +20%y%m%d`_repack.log


script run fine when run manually by ./repack.sh

cron has a very limited path environment which is different then your users. Try using the full path to git.

I've mentioned full path to 'git' command in the script now. This is now working.
Many Thanks for your help.
