       cpupower - Shows and sets processor power related values

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

       cpupower -v|--version

       cpupower -h|--help

       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 over‐
       view of supported commands.

       --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:

	       Input	       Equivalent to

	       all	       all cores

	       0-3	       0,1,2,3

	       0-7:2	       0,2,4,6

	       1,3,5-7	       1,3,5,6,7

	       0-3:2,8-15:4    0,2,8,12

       --version,  -v
	   Print the package name and version number.
