ACPI command in Linux with examples

Last Updated : 11 Jul, 2025

ACPI is the command in Linux that helps the users in managing power settings. It also helps in monitoring the hardware status efficiently. It facilitates with providing essential information such as battery health, CPU temperatures, and fan speeds, providing support in system maintenance and performance optimization. In thi s article we through discussing what are acpi commands and how to utilize ACPI commands effectively through practical examples, helping users enhance their control over power management and hardware configurations on Linux systems.

What is acpi Command?

The `acpi` command in Linux helps in retrieving and displaying the critical system information that is related to power management and hardware status. It facilitates with providing a detailed information such as battery status, CPU temperatures, fan speeds, and power consumption data. It is essential for monitoring system health and optimizing performance. This command is valuable for both troubleshooting hardware issues and implementing effective power management strategies on Linux systems.

Syntax

acpi [options]

Options of acpi Command

The following are the options of acpi command:

Option Description -b, --battery Display battery information including status, charge, and capacity. -t, --thermal Show thermal information such as CPU temperature and cooling device status. -f, --fan View fan information like speed and status. -c, --ac-adapter Check AC adapter status and power supply details. Usage and Examples of acpi Command

The following are the examples of acpi command explaining with its usage:

1. -b, --battery option

The following is used for displaying the battery information including status, charge, and capacity.

acpi -b

2. -a | --ac-adapter

It is used to displays the ac adapter information, the command looks as follows:

acpi -a

3. -t | --thermal

This option is used for displaying the thermal information, the command looks as follows:

acpi -t

4. -c | --cooling

acpi --help

11. -v | --version

It is used in shows the output version of acpi information:

acpi -version

Difference between acpi, acpi-listen and acpi_call Commands

The following are the difference between acpi, acpi_listen and acpi_call Commands:

Feature acpi Command acpi_listen Command acpi_call Command Purpose It used for displaying the ACPI information like battery status, thermal data, etc. It is used for listening the ACPI events and displays corresponding information. It executes ACPI methods from userspace for advanced system control. Information It providess Static ACPI data It provides Real-time ACPI event monitoring It provides the dynamic ACPI method execution for system configuration tasks

Output

It helps in showing the current system hardware state and configurations.

It shows the events that are triggered by acpi. It is useful for scripting and debugging.

It executes the specific acpi methods providing direct control of system.

Usage Monitoring system health and hardware status Real-time debugging of ACPI events Advanced system configuration and power management tasks Features of ACPI Command

The following are the features of acpi command:

Hardware Monitoring: It provides the detailed information regarding the hardware components such as battery status, CPU temperatures, fan speeds, and power consumption, providing the support in system health monitoring.
System Health Assessment: It facilitates the users to assess overall system health by displaying critical ACPI data, including thermal conditions and power supply details.
Diagnostic Tool: It act as a diagnostic tool for troubleshooting hardware-related issues and optimizing power management strategies based on real-time data.
Scripting Support: It facilitates with scripting and automation by retrieving ACPI information that can be used for scripting solutions and monitoring scripts.
