NAME
       apm - interface with the APM subsystem

SYNOPSIS
       apm [ -VvmMsSdin ]

DESCRIPTION
       This  command  requires  the Advanced Power Management subsystem.  If run without arguments it reads /proc/apm and presents the output in a
       human-readable format.

       Given a -S or -s option it requests that the machine be put into the APM standby or the APM  suspend  state,  respectively.   For  a  brief
       description of these states, see apmd(8).

OPTIONS
       -V, --version
              Print the version of the program and exit.

       -v, --verbose
              Also  print  version  information  for the APM subsystem.  The APM subsystem consists of power-management hardware, firmware usually
              referred to as the APM BIOS and a driver in the operating system kernel.

       -m, --minutes
              Print the time remaining as a number of minutes.  The default is to print the time remaining in "hours:minutes" format.

       -M, --monitor
              Continuously monitor and update the status information.  Assumes that the standard output is a terminal.

       -S, --standby
              Request that the machine be put into the APM standby state.

       -s, --suspend
              Request that the machine be put into the APM suspend state.

       -d, --debug
              Print APM status information in a format more useful for debugging.  Implies -v.
