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.
