What command is used to edit the sudoers file for granting sudo privileges?

The command used to edit the sudoers file is visudo. This utility is specifically designed for safely editing the sudoers file, which governs who has permission to use sudo and what commands they can run with elevated privileges.

One of the most important features of visudo is that it performs syntax checking when you attempt to save changes. This helps to prevent configuration errors that could lock you out of sudo access. If the syntax is incorrect, visudo will alert you and not save the changes, ensuring the system remains secure and functional.

Additionally, visudo typically uses the user's default text editor, which can be configured in the user's environment. This command is widely used for its safety and reliability when managing sudo privileges on a Unix-like operating system.
