I have a shellscript which can be successfully executed in UNIX with command sh Shell_script.sh; but I want it to run automatically. So I just configured a cronjob to run the script using crontab -e.

The cronjob added is below:

0 7-23 * * * * /home/folder1/folder2/Shell_script.sh > /dev/null 2>&1

I want it to be executed hourly from 7AM to 11PM every day.

My shell script has a she-bang #!/bin/bash. I am getting a mail every hour with the content:

Your "cron" job on servername * /home/folder1/folder2/Shell_script.sh > /dev/null 2>&1

produced the following output:

sh: +61: execute permission denied

You have extra * in your cron line which is interpreting as Username. Once you delete it it will be fine executed.

also consider if your Shell_script.sh is not executable, you need run with sh (if it's written in sh) or bash if it's bash written.

0 7-23 * * * bash /home/folder1/folder2/Shell_script.sh > /dev/null 2>&1

    Thank you for pointing out my mistake. I have edited my cronjob. Hope it works in the next execution.

  • if you run with bash your_script.sh you no need to worry about executable. you can make it executable with chmod +x your_script.sh. I never used cron to sending mail, so not sure if it will send mail if was not able to execute, but that's sounds it should be Aug 30, 2018 at 6:51
  • Thank you so much....Its working fine now....Also used chmod +x your_script.sh.
