Homebrew is a superb tool for Mac for managing the installation of software. It's core command is brew and it calls packages of software formula. If you are intrigued then you can check out the list of Formula in the brew Github repository.

Using an Access Token for the first time

Configure Git to use the osxkeychain

By default, git credentials are not cached so you need to tell Git if you want to avoid having to provide them each time Github requires you to authenticate. On Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account.

You can tell Git you want to store credentials in the osxkeychain by running the following:-

	// 3 sequential async calls
	for {
	aaa <- WS.url("http://aaa.com").get()
	bbb <- WS.url("http://bbb.com").get()
	ccc <- WS.url("http://ccc.com").get()
	} yield {
	// Construct th result using aaa, bbb, and ccc
	}

	#!/bin/bash

	# create directory for python install
	sudo mkdir -p /opt/bin
	sudo chown -hR core:core /opt
	cd /opt

	# check for newer versions at http://downloads.activestate.com/ActivePython/releases/
	wget http://downloads.activestate.com/ActivePython/releases/3.6.0.3600/ActivePython-3.6.0.3600-linux-x86_64-glibc-2.3.6-401834.tar.gz
	tar -xzvf ActivePython-3.6.0.3600-linux-x86_64-glibc-2.3.6-401834.tar.gz

	#!/bin/sh

	VERSION="0.1-SNAPSHOT"
	SCALA_VERSION="2.12.3"

	echo "Do you wish to use the current directory for the project root? (y/n)?"
	echo "Note: If (n) then the project will be created in a sub-directory of the current one."
