What is Root User?
The superuser account in Unix/Linux systems with unrestricted access to all commands and files.
The root user (UID 0) has complete control over the system. Root can read, write, and execute any file, install software, modify system configurations, and manage other user accounts.
Because of its power, running as root is dangerous — a single mistake can damage the entire system. Best practice is to use sudo for temporary privilege escalation instead of logging in as root directly.
