The Root User and Sudo

  • Root: The superuser (administrator) with unlimited power. They can read any file and destroy the system. Logging in as root directly is dangerous and discouraged.
  • Sudo (SuperUser DO): The command used to temporarily grant administrative privileges to a standard user. It allows you to run a single command with root powers (e.g., sudo apt update) while remaining logged in as your normal user. This provides an audit trail and prevents accidental system damage.
