If you use Linux operating system, then you must have witnessed situations where you had to enter your sudo password several times to execute a command. It should not be a big deal, but sometimes it can be cumbersome especially if you are working on a task that involves multiple commands. The good news is that you can avoid entering sudo password every time you execute a particular command. In this post, we are going to explore how to run particular commands without sudo password in Linux.

The method we will use involves adding additional permissions to the command via the sudoers file. In most Linux distributions, the sudoers file is located in the "/etc/sudoers" directory. Before we make any changes to the sudoers file, we need to back it up to avoid any critical issues. To do this, issue the command below in your terminal, and enter your sudo password:

sudo cp /etc/sudoers /etc/sudoers.bak

Once we have backed up the sudoers file successfully, we can then proceed to add the necessary permissions. To do this, we will use the visudo command. First, open the sudoers file using the command below:

sudo visudo

Next, add a new line at the end of the file by typing the following:

username ALL=(ALL) NOPASSWD:/usr/bin/command

Replace "username" with your Linux username and "command" with the command you want to run without entering your password. For instance, if I want to run the "apt-get update" command without entering the password, I will use the following command:

user1 ALL=(ALL) NOPASSWD:/usr/bin/apt-get update

You can also add multiple commands by separating them with a comma. Once you have added the new line, save the changes and exit the sudoers file. If you have made any syntax errors, visudo will alert you before you save the changes.

From now on, when you execute the specified command, you will not be prompted to enter your sudo password anymore. However, it's essential to note that adding extra permissions to the sudoers file can pose a security threat to your system, especially if an unauthorized user gains access to your account. Ensure that you only add permissions to safe and reliable commands.

In conclusion, skipping the sudo password when executing a command in Linux can save you time and make your workflow easier. However, ensure that you add extra permissions to the sudoers file cautiously to avoid any security issues. Follow the above steps, and you will have success in running particular commands without sudo password.
