What command is used to halt a Linux system ?
Correct answer: A. init 0
- A. init 0
- B. Shutdown -t
- C. Shutdown -g -y0
- D. Ctrl+Alt+Del
Explanation
`init 0` changes the system to runlevel 0, which shuts the system down. `Ctrl+Alt+Del` commonly triggers a reboot rather than a normal halt, and the other shutdown syntaxes are not generally valid as written.
