While it may be convenient, disabling the password prompt for sudo is a security risk and generally not recommended. It essentially grants any user on the system root privileges, potentially leading to accidental or malicious system modifications. However, there are specific situations where it might be necessary, such as automating tasks on a server.
1. Backup the sudoers file
sudo cp /etc/sudoers /etc/sudoers.bak
This creates a backup of the original sudoers file in case you need to revert changes.
2. Edit the sudoers file
sudo visudo
This opens the sudoers file in your default editor. Be extremely cautious while editing this file, as any syntax errors can lock you out of your system.
3. Modify the file
At the end of the file, add the following line:
<username> ALL=(ALL:ALL) NOPASSWD: ALL
Replace <username> with your actual username. This grants you the ability to run any command with sudo without entering a password.
4. Save and exit the file
5. Close your terminal and log out
This ensures the changes take effect.
