The sudo command in Linux stands for "superuser do" and is used to execute commands with elevated privileges. It allows authorized users to perform administrative tasks without needing to log in as the root user.
By using sudo, users can execute specific commands or run entire scripts with the necessary permissions to modify critical system files, install software, or perform other administrative actions. This helps maintain security and prevents common mistakes or accidental damage that can occur when logged in as the root user.
To use the sudo command, users need to have their account configured in the sudoers file with the appropriate permissions. This file defines which users or groups can run specific commands as the root user or as other authorized users.
When executing a command with sudo, users are prompted to enter their own password to authenticate themselves before the command is run. This serves as an added layer of security, ensuring that only authorized individuals can access higher privileges.
Overall, the sudo command is a vital tool for managing and securing Linux systems by allowing controlled access to administrative tasks while maintaining individual accountability and reducing the risks associated with unrestricted root access.
