Hi, thanks for your contribution! I'm still on ZSH 5.2 and didn't try the last development version of ZSH, but I can't see why this shouldn't work with my version. Something that I found was that % cpupower frequency-set -g yields as options: > available    cpufreq      governors:   performance  powersave  i.e., I can select "available", "cpufreq", ... as options. This seems to be a bug. I'm using cpupower 4.6 on Debian Testing.
