Mac OS X (laptops ??) only : control hibernation state more easily from Terminal.app

sudo pmset -a hibernatemode 1 sets hiberate on.

sudo pmset -a hibernatemode 0 sets hibernate off.

from the pmset man page:

0001 (bit 0) enables hibernation; causes OS X to write memory state to

hibernation image at sleep time. On wake (without bit 1 set) OS X will

resume from the hibernation image. Bit 0 set (without bit 1 set) causes

OS X to write memory state and immediately hibernate at sleep time.

I often change my MacBook's sleep state. So I created a function for bash to make it a little easier.

Usage:

hibernate (on | off)

"hibernate on" will set your laptop to hibernate if the lid is closed.

"hibernate off" will set your laptop to sleep if the lid is closed.

### note : "proper" indentation isn't preserved on the website

function hibernate()

{

case "${1}" in

on)

sudo pmset -a hibernatemode 1

echo Hibernate mode on.

;;

off)

sudo pmset -a hibernatemode 0

echo Hiberate mode off.

;;

*)

echo "I'm sorry Dave, but I can't do that."

;;

esac

}

To make things easier, add the proper line in your /etc/sudoers file so that your user may invoke pmset without a password. Here's how mine looks:

bwayne luna = NOPASSWD: /usr/bin/pmset

Don't forget that you must edit sudoers with `sudo visudo` from Terminal.app, and not by another text editor.

Sorry this is so Mac OS specific.
