Bash script to enable / disable turbo on the CPU in Linux. Change permissions: sudo chmod a+x switch-turbo.sh Run the script: sudo ./switch-turbo.sh

switch-turbo.sh

#!/bin/bash

status=$(head /sys/devices/system/cpu/intel_pstate/no_turbo | grep -o '[0-1]')

if [ $status = 0 ]; then
        echo "Switching CPU-turbo: OFF"
        echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo
else
        echo "Switching CPU-turbo: ON"
        echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo
fi

Useful but over on my branch I cleaned up the subcommand for status. Nothing much but is a bit cleaner.
