telinit is /sbin/telinit
“telinit may be used to change the SysV system runlevel. Since the concept of SysV runlevels is obsolete the runlevel requests will be transparently translated into systemd unit activation requests.”
init is /sbin/init
“systemd, init – systemd system and service manager”
reboot is /sbin/reboot
halt, poweroff, reboot – Halt, power-off or reboot the machine
shutdown is /sbin/shutdown
shutdown – Halt, power-off or reboot the machine
systemctl ist /usr/bin/systemctl
systemctl may be used to introspect and control the state of the “systemd” system and service manager. Please refer to systemd(1) for an introduction into the basic concepts and functionality this tool manages.
wall
wall “hello world”
