# apm(1)

interface with the APM subsystem

## 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)](/apmd/8.md).

## 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.
