Remotely install Homebrew over ssh.

remote-headless-brew.md

Look up OS X release.

there$ sw_vers -productVersion
10.9.5

Go to https://developer.apple.com/downloads/ and get the best release of Command Line Tools for Xcode. For example, the latest version for OS X 10.9 is http://adcdownload.apple.com/Developer_Tools/Command_Line_Tools_OS_X_10.9_for_Xcode__Xcode_6.2/commandlinetoolsosx10.9forxcode6.2.dmg.

After downloading the DMG, run the script to extract the PKG file, copy it to the remote host, and install everything.

here:Downloads$ ./remote-headless-brew.sh me@there [commandlinetools*.dmg]

#! /bin/bash -ex

# First download the OS X Command Line Tools for Xcode, then run this
# script to remotely install Homebrew.

there=${1-bonehead@192.0.2.1}
dmg=${2-commandlinetoolsosx10.9forxcode6.2.dmg}

# mount up the DMG
mnt=$(hdiutil attach "$dmg" |grep -o '/Volumes/.*')

# get the name of the PKG
pkg=$(find "$mnt" -iname '*.pkg')

# copy it over
rsync "$pkg" "$there:"

# strip off the local path
pkg=$(basename "$pkg")

set +e
# remotely extract/install the package
ssh -t "$there" "set -ex
	PATH=\"\$PATH:/usr/local/bin\"

	xcode-select -p ||sudo installer -pkg \"$pkg\" -target /
	xcode-select -p

	! brew info
	# TODO: get rid of the tty so ruby doesn't wait for user
	ruby -e \"\$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)\"
	brew info
	brew doctor
"

# unmount
hdiutil detach "$mnt"
