wheel group
also: sudoers group, admin group
The wheel group is a special user group that grants members the ability to execute commands with elevated privileges using sudo, without requiring a password prompt in many Linux distributions.
The wheel group is a traditional Unix/Linux group used for privilege escalation and administrative access. Members of the wheel group can run commands as the root user (or other users) via sudo, allowing unprivileged users to perform administrative tasks when needed.
To add a user to the wheel group, use: usermod -aG wheel username. After adding a user to the group, they must log out and back in for the change to take effect.
On many distributions, the wheel group is pre-configured in /etc/sudoers to allow passwordless sudo access or to require only the user's own password. For example: %wheel ALL=(ALL) ALL or %wheel ALL=(ALL) NOPASSWD: ALL grants all group members full sudo privileges.
