While working with Linux, we find that access to some files or performing sensitive operations requires users to have elevated privileges. The sudo command temporarily elevates user privileges allowing a user to execute sensitive commands or access files without restrictions.

Edit the /etc/sudoers file using visudo command

# backup /etc/sudoers file
sudo cp /etc/sudoers /root/sudoers.bak

# edit with visudo
sudo visudo

# all commands without password for wheel group
%wheel  ALL=(ALL)       NOPASSWD: ALL

# save and exit
