admin crontab won't run sudo command

sudo: no tty present and no askpass program specified

Hi I am getting the above error when ever I try to get the following crontab to run.

*/5 * * * * sudo bash /home/admin/scripts/monitor.sh /dev/null 2>&1

I am using nano as the editor to edit the admin user crontab - note this is not root user.

EDITOR=nano crontab -e -u admin

Solution

  • 1) Disable requiretty in sudoers file

    2) Permit script execution without password:

    admin    ALL=(ALL) NOPASSWD: /home/admin/scripts/monitor.sh

    3) I'm not sure but you don't need specify bash after sudo. Just add #! /bin/bash at the begin of the script

    */5 * * * * sudo /home/admin/scripts/monitor.sh /dev/null 2>&1
