Pmset (Paperback)

High Quality Content by WIKIPEDIA articles! In computing, pmset is a command line utility to manipulate power management settings under the Darwin and Mac OS X operating systems. It can assign sleep settings, schedule sleep and wake times, and display power information. The pmset utility first appeared in Darwin 6.0.1 and Mac OS X 10.2 "Jaguar." It has been updated periodically since its introduction, and is still available as of Darwin 10.3 and Mac OS X 10.6 "Snow Leopard." The utility sets or lists power management settings. Some of the functionality provided by the utility is available through the GUI interface of the Energy Saver preference pane. However, pmset allows for greater flexibility and access to several options not available in the GUI. The utility can set different power management settings depending on usage scenario. Different settings can be applied for when the machine is running off a charger, battery, UPS, or all three.
