This script is extremely simple. I wrote it while trying to slow down a VIA C3 processor with the Linux powersave tools. This script was first made public here.
You can kill the script at the command line with <cntrl>-C in most shells.
#! /bin/bash # 2004/01/07 # output cpu speed every second or so until terminated. while [ true ]; do powersave -r #use this line instead if you don't have powersave #grep MHz /proc/cpuinfo | cut -d: -f2 sleep 1 done
