sudo without password code example

Example 1: sudoers nopasswd

# user
user	ALL=(ALL:ALL) NOPASSWD: ALL

# group 
%sudo	ALL=(ALL:ALL) NOPASSWD: ALL

Example 2: debian sudo without password

#1. Open the /etc/sudoers file (as root, of course!) by running:
sudo nano /etc/sudoers

#2. At the end of the /etc/sudoers file add this line:
username ALL=(ALL) NOPASSWD:ALL

Example 3: run command without sudo password

# Run `visudo` to edit the file `/etc/sudoers`:
sudo visudo

# For example, to allow the `shutdown` command to run without a password. 
# Add this to the file, replacing `myusername` with your own login name for your PC:
myusername ALL = NOPASSWD: /sbin/shutdown

# NOTE: `sudo` is still required to run the command so you still have to specify the command as:
sudo shutdown
