How to run sudo command without a password on a Linux or Unix

by

To run the sudo command without a password on a Linux or Unix system, you need to edit the /etc/sudoers file. The sudoers file is used to control the authorization and access of users to run sudo.

Here’s the basic process to run the sudo command without a password:

  1. Open a terminal window.
  2. Open the sudoers file using a text editor with sudo privilege:
sudo nano /etc/sudoers
  1. Find the following line in the sudoers file:
# User privilege specification
root ALL=(ALL:ALL) ALL
  1. Below this line, add the following line to specify the user who should be allowed to run the sudo command without a password:
user ALL=(ALL) NOPASSWD: ALL

Note: Replace “user” with the actual username you want to allow.

  1. Save and close the sudoers file.

Now, the specified user should be able to run the sudo command without a password. It’s important to note that giving users the ability to run sudo without a password can pose a security risk. It’s recommended to only do this for trusted users.
