Best would be you provide the output of

crontab -l

And the script you are trying to execute.

Hi,

Here is the output of the crontab -l

[root@test lib]# crontab -l
1 * * * * /home/ssagar/cronnew.sh

And the script is

echo "welocme" >> output.txt

The above script was simple as i am trying to test whether cron is working or not. When i execute the above script manually it will be successfully executed.

You should use an absolute path to your output file.

echo "welcome" >> /home/ssagar/output.txt

You might try using an absolute path for your output.txt file, so that you know for sure where it ends up when the script is run by cron.

Edit: oops, too slow.

If you want to see what cron has for settings, add the following line to your script and look for the output in /tmp/settings.txt

Code:

set > /tmp/settings.txt

Hi,

Hi have tried as mentioned above but still cron job is not getting executed.

Ensure that /home/ssagar/cronnew.sh has execute permissions, also when were you expecting this to run?

Your cron job sets it to run once an hour at 1 minute past the hour.

To check my cron jobs, I use to run the script with

Code:

 
command xx && DISPLAY=:0 notify-send "OK" "command xx" || DISPLAY=:0 notify-send --urgency=critical "FAILED" "command xx"

You may need to use /bin/echo instead of plain echo.
