acpi

ACPI, which stands for Advanced Configuration and Power Interface, is a command line tool that provides information about various aspects of a computer's power management and hardware configuration. It is typically available on Linux and other Unix-like operating systems.

The acpi command can display information about the battery status, such as the current charge level, remaining capacity, and estimated time of operation. It can also provide details about the computer's thermal information, including temperature readings for different components like CPU, GPU, and motherboard.

In addition, ACPI can report data about the computer's fan speeds and cooling devices. This information helps in monitoring the system's temperature and ensuring optimal performance.

The command can retrieve and display information about plugged-in power supply units, including the model, manufacturer, capacity, and charge status. It can also indicate whether the computer is running on battery power or connected to an AC adapter.

ACPI can be used to control and manage various power-related settings as well. It allows users to hibernate, suspend, or shut down the system using simple commands. It can also modify power-related behavior, such as adjusting the system's sleep settings or configuring the behavior of power buttons.

Furthermore, acpi can provide information about ACPI events, like power button presses or lid closures, allowing users to customize the system's response to these events.

The command supports a wide range of options and parameters to customize the output and query specific information. It is often used in shell scripts or system monitoring tools to extract and analyze power and hardware data programmatically.

Using ACPI, system administrators can monitor power usage, troubleshoot power-related issues, and fine-tune power management settings to optimize energy efficiency and prolong battery life.

The acpi command is a powerful utility that provides essential information and control over power management and hardware configuration in command line environments. Its versatility makes it a valuable tool for both casual users and system administrators.
