    You shouldn’t edit the /etc/sudoers file with any sort of script. There’s a reason for the visudo command. Edits to the sudoers file should be rare and well-controlled.

    That being said, if your editor for the visudo command is vi, you can run something like :%s/^# %wheel/%wheel/ to uncomment all of the lines what start with %wheel.

    Or, if you reeeeeeally think it’s necessary:

    sudo sed --in-place 's/^#\s*\(%wheel\s\+ALL=(ALL)\s\+NOPASSWD:\s\+ALL\)/\1/' /etc/sudoers

    Run it without the --in-place first to check the output. Use it at your own risk.
