shell script is not executed after adding it as a crontab job

  • 772

I have added the following crontab job:

sudo crontab -e

enter image description here

58 * * * * ubuntu /home/ubuntu/backup/mysqlbackup.sh
>/home/ubuntu/backup/log/backup.log

I have tried both root and ubuntu users.

When I run the command:

sudo crontab -l

enter image description here

And when I run:

systemctl status cron

enter image description here

But mysqlbackup.sh is not executed. Any idea what is the problem or how can I diagnose what is going wrong?

Note I have added only minutes to test the script

command-line bash cron

    58 * * * * ubuntu /home/ubuntu/backup/mysqlbackup.sh >/home/ubuntu/backup/log/backup.log

    This is incorrect format.

    The format is described in the crontab file:

      # m h  dom mon dow   command

    ubuntu is not a command. Remove it, so the line reads:

      58 * * * *  /home/ubuntu/backup/mysqlbackup.sh >/home/ubuntu/backup/log/backup.log

    Systemwide crontab, specified in /etc/crontab has the user field:

    These files also have username fields,
# that none of the other crontabs do.
[...]
# m h dom mon dow user  command
