Err bitreich.org 70 i 5 Err bitreich.org 70 i 6 As per-process energy measurement is not possible, this is done by Err bitreich.org 70 i 7 querying hardware counters. Hence the energy usage is the net energy Err bitreich.org 70 i 8 usage of the entire system, including other processes. To measure the Err bitreich.org 70 i 9 net usage of a command, subtract the energy usage of the system at Err bitreich.org 70 i 10 idle (e.g. by measuring the energy usage of `sleep 1` or similar).
