Git

Distributed version control system you can't really live without those days.

Installation

Open iTerm and enter command

brew install git

Configuration

• Setup global user name and mail

  git config --global user.name "Your Name"
  git config --global user.email [email protected]
  

• Create a .gitignore file in your $HOME directory with the following content

  .idea/
  .DS_Store
  

  This is a base, https://www.gitignore.io/ is far more precise per OS, IDE, ...

• Define this file as a global

  git config --global core.excludesfile ~/.gitignore
  

SSH

As it's a guide for fresh install, i consider there is no ".ssh" folder in your $HOME

• Create rsa public and private key (if you don't want a passphrase, just pass every question)

ssh-keygen -t rsa -b 4096 -C "[email protected]"

• Start ssh agent

eval "$(ssh-agent -s)"

• Add the created key to it

ssh-add -K ~/.ssh/id_rsa

• Add the created to your Github account

  • Copy the public key to your clipboard

  pbcopy < ~/.ssh/id_rsa.pub
  

  • Go to https://github.com/settings/keys
  • Click on "New ssh key"
