Sandman: A bash script to find all known Vagrant VMs and put them to sleeps. Zzz.

sandman

#!/usr/bin/env bash

# variables
vagrant=""

# functions
errcho() {
    >&2 echo "$*" 
    exit 1
}

check() {
    which "$1" || errcho "Missing dependency: $1"
}

# deps
vagrant=$(check vagrant)

# main
printf "Putting VMs to bed. "

while read line
do
    set -- $line
    # 1:a8533bc 2:utility 3:virtualbox 4:poweroff 5:/Users/colbyolson/src/Work/misc/chef
    [ "$4" = 'running' ] && $vagrant halt $1
    printf "z"
done < <($vagrant global-status --prune)

printf "\n"

INSTALL

$ curl -so /usr/local/bin/sandman https://gist.githubusercontent.com/colby/f98cbc2380db0be48bbb/raw/0b21b0c3580ded26412bcf2b00f32a4d7fd6f9ef/sandman
$ chmod +x /usr/local/bin/sandman

HOWTO

Vagrant now supports global-status, which lists out all known VMs. I've appended --prune to the command so that older or stale VMs are removed.

$ sandman

UNINSTALL

$ rm /usr/local/bin/sandman

Works swell. I think adding an option to specify either halt or `suspend would be helpful. I'll see if I can add it somehow but I'm not making any promises...
