Git

If you are a Linux user then you must already know a little bit about shells, ssh and how to use the command line. If not you probably want to use a different platform as your dance floor.

Let's start a shell and validate the ability to run git from the command prompt:

$ git
The program 'git' is currently not installed. You can install it by typing:
sudo apt-get install git

So I guess it not there. Let's do what it says and install git.

$ sudo apt-get install -y git
sudo: unable to resolve host ip-172-30-0-110

Setting up git (1:1.9.1-1ubuntu0.1) ...

$ git --version
git version 1.9.1

So we got some git. Let's get EDT.

$ git clone https://github.com/codemarc/ElectricDiscoTech

Npm

Now let's see which version of npm is installed:

$ npm -v
The program 'npm' is currently not installed. You can install it by typing:
sudo apt-get install npm

This error message is a little misleading. The real problem is that I forgot to install Node.js which includes npm. There are a variety of ways to get Node.js working on Linux. I like to use a package manager, for ubuntu: 

$ curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
## Installing the NodeSource Node.js 4.x LTS Argon repo...
## Populating apt-get cache...

## Run `apt-get install nodejs` (as root) to install Node.js 4.x LTS Argon and npm

$ sudo apt-get install -y nodejs
get install -y nodejs

So assuming everything went right we should be able to test npm 

$ npm -v
2.14.7

You can update npm using npm. 

$ sudo npm install -g npm
/usr/bin/npm -> /usr/lib/node_modules/npm/bin/npm-cli.js
npm@3.5.0 /usr/lib/node_modules/npm

$ npm -v
3.5.0

Bower

bower is billed as a package manager for the web. What it saves you from is endless hours of searching for source components. If you know the name of a component and its author has created a package for it (most popular components have the by now) then all you need to do to grab a copy using: bower install <package>

To install or update bower run:

$ sudo npm install -g bower
⋮
$ bower -version
1.6.8
