CPUPOWER(1)

💅 CPUPOWER(1) ✨ cpupower Manual ✨

🌸 NAME

cpupower - Shows and sets processor power related values 💖

🦋 SYNOPSIS

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

cpupower -v|--version

cpupower -h|--help

✨ DESCRIPTION

okay so cpupower is literally a whole collection of tools for checking out and tuning your processor's power saving stuff 🔋 it's giving main character energy, no cap.

the manpages for each command (cpupower-<command>(1)) have the deep-dive details on every feature it supports 🤓 and if you want the quick overview, just run cpupower help and it'll show you every command it knows 🫶

🎀 OPTIONS

• --help, -h — the vibe check for this tool 💜 it shows the supported commands and general usage.
• --cpu cpulist, -c cpulist — 🧚 this lets you only show or set values for specific cores. heads up though, not every command accepts it, so check the manpage for whichever command you're using.

some commands go after all the cores by default (usually the *-set ones), while others only look at the first core (usually the *-info ones) 👀

the <cpulist> syntax is based on how the kernel exports CPU bitmasks through sysfs files. here are some examples, bestie:

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 — 🍓 prints the package name and version number. that's it, iconic.
