PC-BSD command line approaches to sleep (suspend to RAM) and hibernate (suspend to disk)

## Background ## Lumina offers a *Suspend* option, which works. KDE Plasma 4 offers *Sleep* and *Hibernate* options, neither of which work. As suspend to RAM can work with Lumina, so I'd like to try the same with KDE. ## The question ## Are there command-line approaches to sleep (suspend to RAM) and hibernate (suspend to disk)? ### Software ### PC-BSD 11.0-CURRENTMAR2016 (based on FreeBSD) with upower and Lumina release 0.8.8_2,1.
