POWERDOWN(1)          UNIX System V(Essential Utilities)           POWERDOWN(1)


NAME
      powerdown - prepare the system for turning off the power

SYNOPSIS
      powerdown [ - Y | -y ]

DESCRIPTION
      The setup command, which is also accessible as a login by the same name,
      initiates an orderly shutdown of the system in preparation for reboot or
      turning off the power.

      It is actually a front-end for the shutdown(1) command.

      There are two options:

      -Y    Starts a shutdown with a grace period of 0 seconds.

      -y    Starts a shutdown with a grace period of 60 seconds.

      If neither option is specified, the user is prompted to confirm the
      intention to shutdown the system.

SEE ALSO
      shutdown(1)

NOTES
      If the powerdown login is not under password control, anyone can shut
      down the system.
