Sudo

In a nutshell, sudo permissions are defined in /etc/sudoers and /etc/sudoers.d/. Permissions are defined like so:

%groupname workstation=/bin/command
username workstation=/bin/command
username workstation=(run-as user) /bin/command

Replace any of the above with ALL to have it match anyone. eg:

ALL ALL=ALL

You can use NOPASSWD: /bin/command to have it not prompt for the user's password.

You can verify whether your changes worked by listing sudo access:

sudo -l

Configure using /etc/sudoers.d/

For the configs in /etc/sudoers.d/ to work, you must place an existing file with perms set to 0440 into /etc/sudoers.d/.

You cannot create the file directly in /etc/sudoers.d/ because it will not work!

Also ensure the #includedir directive is defined in /etc/sudoers.
