Major administration tasks include user account management, hardware and software management, system backup, system monitoring performance tuning, troubleshooting system problems, security auditing, and documentation.

System administration in Linux (or Unix) is usually done using shell instead of using fancy GUI tools, even though there are GUI tools for some administration tasks.
