Whenever setting up a new machine, I forget to properly configure Git. Usually it is just the base things like name and email, but there are a few other useful settings.

It is easy enough to run commands like git config --global user.name "Mega Man" to setup Git options globally, but when setting up multiple options, it is easiest to directly edit the settings in a file called .gitconfig. If you want to start working with a .gitconfig file, run:

touch ~/.gitconfig

to create the file in your home directory. Go ahead and open it up in the editor of choice. Below is what my .gitconfig looks like. I typically try to keep it as simple as possible.

  name = Your Name
  email = youremail@host.com
  helper = cache
  ui = true
  editor = vim
  excludesfile = ~/.gitignore_global

The credential setting for helper = cache defaults to a 15 minute remember period for credentials. This is helpful for not having to continually type in a password every time you need to push or pull.

The color setting for ui = true makes working with Git from the command line just a little more colorful.

The core setting for editor = vim set the default editor for writing messages in Git. You can set this to whatever editor you want.

The excludesfile setting tells Git to use the specified file as a computer-wide .gitignore file, which is great for ignoring files like .DS_Store. I wrote an in-depth post on using .gitignore if you are interested in learning more about it.

Beyond that, I keep my Git config lean and clean.
