Installing Git and Github Setup

Git is a version control system very popular amongst developers. After installing Homebrew, installing git is a very simple task:

brew update
brew install git

After the installation is complete, run brew doctor. Check Homebrew warnings section if homebrew displays any warnings / errors.

In order to check git installation, run git --version. Running which git should output /usr/local/bin/git.

Next we will set your Github user and email for git.

If you do have a Github account, create one. Add your user name and email in git using:

$ git config --global user.name "Your Github Full Name"
$ git config --global user.email "Your Github Email Address"

git config --global push.default matching

These options will be added into the ~/.gitconfig file. You can check the contents of this file using vim ~/.gitconfig command.

The official Git setup guide recommends the HTTPS method (over SSH). In order to set HTTPS connection, we will enable using Git password caching (article):

• Check if osxkeychain is installed: git config --global credential.helper osxkeychain
• If the osxkeychain is not installed:
  • Download it using curl: curl -s -O \ https://github-media-downloads.s3.amazonaws.com/osx/git-credential-osxkeychain.
  • Fix the permissions on the file so you can run it: chmod u+x git-credential-osxkeychain
  • Install the helper in the same directory as git: sudo mv git-credential-osxkeychain \ "$(dirname $(which git))/git-credential-osxkeychain"
• Tell git to use osxkeychain using the credential.helper config: git config --global credential.helper osxkeychain

The next time you clone an HTTPS URL that requires a password, you'll be prompted for your username and password, and to grant access to the OSX keychain. After you've done this, the username and password are stored in your keychain and you won't be required to type them in to Git again.

DS_Store

Remember to always add .DS_Store (a hidden OSX system file added to all folders) to the .gitignore file for all git projects.

Github app

Download the Github app and open it. follow the on-screen instructions to set it up. This will create a SSH key in your Github account. This will be used by the app to communicate with your account. A paid alternative is Tower.

Although a GUI git client has it's advantages, consider using the command line for the majority of your git-related tasks.

Git Ignore File

The majority of your projects will ignore certain files. Use this gitignore example to add default ignore files.

Git Repos Terminal Setup

Next we will set OSX Terminal to show the git branch and state.
