root is the user name or account that by default has access to all commands and files on a Linux or other Unix-like operating system with full privileges. Root access is often necessary for performing commands in the system, especially commands that affect system files because root is so powerful, it’s recommended to only request root access when necessary, as opposed to logging in as the root user.
