Have you ever encountered a situation where you need to use "sudo" command in Ubuntu but it keeps asking you for a password? It can be quite frustrating and time-consuming, especially if you need to use "sudo" frequently. However, there is a way to use "sudo" command without a password in Ubuntu.
The trick is to modify the "sudoers" file in Ubuntu, which controls the access to "sudo" commands. By default, the "sudoers" file requires a password for any "sudo" command. But, with some tweaks, you can allow certain users or groups to use "sudo" without a password.
To modify the "sudoers" file, you need to use the "visudo" command in Ubuntu. "Visudo" is a special command that opens the "sudoers" file in a safe and controlled manner, preventing accidental changes or syntax errors. Here are the steps:
- Open the terminal in Ubuntu by pressing "Ctrl + Alt + T" shortcut key.
- Type "sudo visudo" command and press enter.
- Enter your password when prompted.
- Use the arrow keys to navigate to the end of the file.
- Add the following line to allow a specific user to use "sudo" without a password:
- username ALL=(ALL) NOPASSWD: ALL
- Replace "username" with the actual username that you want to allow.
- Save and exit the file by pressing "Ctrl + X", then "Y", and then "Enter" key.
That's it! Now, the specified user can use "sudo" command without a password in Ubuntu. However, this approach can have security implications, as it removes the password prompt for "sudo" commands. So, use it with caution and only for trusted users.
In summary, you can use "sudo" command without a password in Ubuntu by modifying the "sudoers" file. This trick can save you time and frustration, especially if you need to use "sudo" frequently. However, be mindful of the security implications and use it judiciously.
