## SYNOPSIS

**cpupower \[ -c cpulist \] \<command\> \[ARGS\]**

**cpupower -v\|--version**

**cpupower -h\|--help**

## DESCRIPTION

**cpupower  is a collection of tools to examine and tune power saving** **related features of your processor.**

**The manpages of the commands (cpupower-\<command\>(1)) provide detailed** **descriptions of supported features. Run cpupower help to get an overview** **of supported commands.**

## Options

- **--help, -h**

  **Shows supported commands and general usage.**

- **--cpu cpulist, -c cpulist**

  **Only show or set values for specific cores.** **This option is not supported by all commands, details can be found in the** **manpages of the commands.**

  **Some commands access all cores (typically the \*-set commands), some only** **the first core (typically the \*-info commands) by default.**

  **The syntax for \<cpulist\> is based on how the kernel exports CPU bitmasks via** **sysfs files. Some examples:**
