Okay, what about #! /bin/zsh # # this file: # https://dataswamp.org/~incal/conf/.zsh/cpu cpu-stats () { local time=$(date +%s) local gov=$(cpufreq-info -p | awk '{print $3}') local back=$(jobs -l | wc -l) local temp=$(sensors -j | jq -a '.["k10temp-pci-00c3"].Tdie.temp1_input') local cores=$(getconf _NPROCESSORS_ONLN) local avg=$(awk '{print $1}' /proc/loadavg) local load=$(( $avg * 100/$cores )) local freq=("${(@f)$(awk '/cpu MHz/{print $4}' /proc/cpuinfo)}") local fan=$(sensors | awk '/cpu_fan/{print $2 " RPM"}') echo "time ${time}" echo "governor ${gov}" echo "background processes ${back}" echo "CPU temperature ${temp}C" printf "system load %.1f%%\n" $load echo "CPU fan speed ${fan}" echo -n "CPU frequencies " for f in $freq; do echo -n "$f " done echo "MHz" } test-cpu () { local cores=$(getconf _NPROCESSORS_ONLN) local pids=() local g for g in $(cpufreq-info -g); do sudo cpufreq-set -g $g repeat 3 { sleep 60 cpu-stats } repeat $cores { perl -e '1 while 1' & pids+=($!) repeat 10 { sleep 6 cpu-stats } } done for p in $pids; do kill $p done } -- underground experts united https://dataswamp.org/~incal
