Granting access with sudo

User smurf is now very sad as he can’t add user bob or install the terminator package on the system. You can use the visudo command to grant user smurf the permissions to run the two privileged commands he wants.

Run the visudo command as the root user:

root@ubuntu-linux:~# visudo

This will open up the file /etc/sudoers so you can edit it:

# This file MUST be edited with the 'visudo' command as root. 
#
# Please consider adding local content in /etc/sudoers.d/ instead of 
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
