sleep_info.sh är ett bash-script skrivet för OS X 10.10 ”Yosemite” som berättar om datorns inställning vad gäller sömn och när/varför den somnar och vaknar (denna delen kräver att man är admin-användare). Om någon hindrar datorn från att sova, kommer man att få se vad det är.
Så här kan outputen se ut när man kör i teminalförnstret (som admin-användare):
