What is tested
The quiz checks the commands you use on any server: finding where you are with pwd, following a log with tail -f, the difference between > and >>, checking free disk space with df -h and finding which process holds a port with ss. It also covers what chmod 755 gives to other users, what sudo does, why kill -9 should be a last resort, how systemctl enable --now differs from start, which permission lets you enter a directory and which file lists user accounts.

Practise on a real shell
The fastest way to fix a wrong answer is to try the command. If you do not have a Linux machine, use Windows Subsystem for Linux, a free cloud shell, or a small virtual machine. Then work through a short routine:
- Create a folder, add files, change their permissions and read the result with ls -l.
- Start a long-running command, find it with ps, and stop it with kill.
- Install a package, start its service with systemctl and read its log with journalctl.
- Pipe grep into sort and uniq -c to count repeated lines in a log.
Keep the Linux commands cheat sheet open while you practise, and work out modes in the chmod calculator.
