install/configure: git & GitHub in coordination w/ Ionic workflows

[dpcunningham]

Per these reccs... from Ionic.

Resources:

• The online git book...

• The GutHub help docs...

  • Creating, cloning, and archiving repositories
  • Cloning a repository from GitHub

• One quick example: cloning to a new local dir:

  git clone https://github.com/dpcunningham/ionic4_tutorial_photo-gallery new_i4_tut_photo-gallery`

For git itself:

• Downloads (lists latest version)
• Download for Linux and Unix
• NB: you can use git to update git to the latest development version (not recommended).

For the latest stable version for your release of Debian/Ubuntu: # apt-get install git For Ubuntu, this PPA provides the latest stable upstream Git version: # add-apt-repository ppa:git-core/ppa # apt update; apt install git

Alternatively (via Ask Ubuntu, w/ more details and work-arounds) you can:

Use the PPA from the maintainers of git on Ubuntu:

sudo apt-add-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git

If you don't know what PPAs are, first read What are PPAs and how do I use them?

If you receive an error about add-apt-repository command not found you may need to add the python-software-properties package or software-properties-common depending on your Ubuntu version.

• Ubuntu 14.04: sudo apt-get install software-properties-common

• Ubuntu 13.10 or earlier: sudo apt-get install python-software-properties
