Mac/Linux Setup

Installing Git

Git is actually installed on MacOS, but we'll be reinstalling it so that we'll have the newest version:

go to https://git-scm.com/downloads
download the software for Mac
install Git choosing all of the default options

Once everything is installed, you should be able to rungiton the command line. If it displays the usage information, then you're good to go!

If you run into any issues, let us know in the forum.

Configuring Mac's Terminal

We're about to configure the Terminal to display helpful information when in a directory that's under version control._This is an optional step!_You do not need to re-configure your terminal for Git to work. You can complete the entire course without reconfiguring it. However, reconfiguring the Terminal makes it significantly easier to use.

If you choose to configure your Terminal, here's what it should look like when you're finished.

The terminal application on MacOS. The terminal has been configured to display version control information.

Configuration Steps

To configure the terminal, we'll perform the following steps:

download the zipped file
move the directory udacity-terminal-config to your home directory and name it .udacity-terminal-config (there's a dot at the front, now!)
move the bash_profile file to your home directory and name it .bash_profile (there's a dot at the front, now!)
- if you already have a .bash_profile file in your home directory, transfer the content from the downloaded bash_profile to your existing .bash_profile

Download the zipped file in the Resources pane to get started.

First Time Git Configuration

Before you can start using Git, you need to configure it. Run each of the following lines on the command line to make sure everything is set up.

# sets up Git with your name

git config --global user.name 
"
<
Your-Full-Name
>
"
# sets up Git with your email

git config --global user.email 
"
<
your-email-address
>
"
# makes sure that Git output is colored

git config --global color.ui auto


# displays the original state in a conflict

git config --global merge.conflictstyle diff3

git config --list

Git & Code Editor

The last step of configuration is to get Git working with your code editor. Below are three of the most popular code editors. If you use a different editor, then do a quick search on Google for "associate X text editor with Git" (replace the X with the name of your code editor).

Atom Editor Setup

git config --global core.editor 
"atom --wait"

Sublime Text Setup

git config --global core.editor 
"'/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl' -n -w"

VSCode Setup

git config --global core.editor 
"code --wait"

If you have any questions, post them on the forum.
