SYNOPSIS
poweroff [OPTIONS...]
reboot [OPTIONS...]
halt [OPTIONS...]
DESCRIPTION

NOTES
These commands are implemented in a way that preserves basic compatibility with the original SysV commands. systemctl(1) verbs poweroff, reboot, halt provide the same functionality with some additional features.
Note that on many SysV systems halt used to be synonymous to poweroff, i.e. both commands would equally result in powering the machine off. systemd is more accurate here, and halt results in halting the machine only (leaving power on), and poweroff is required to actually power it off.
