telinit [OPTIONS] COMMAND

telinit changes the SysV init runlevel. On systemd systems, runlevel requests are transparently translated to systemd target activations:
- 0 → poweroff.target
- 1 → rescue.target
- 2-4 → multi-user.target
- 5 → graphical.target
- 6 → reboot.target

--no-wall

Don't send wall message before reboot/poweroff

0 - Power off
1 - Single-user/rescue mode
2, 3, 4 - Multi-user modes
5 - Multi-user with GUI
6 - Reboot
q, Q - Reload configuration

The SysV runlevel concept is obsolete on systemd systems. Use `systemctl` commands instead for native systemd operation. Provided for backwards compatibility.

telinit originates from SysV init, predating systemd. On systemd systems, it's a compatibility wrapper that translates runlevels to systemd targets.
