If ~/.path exists, it will be sourced along with the other files, before any feature testing (such as detecting which version of ls is being used) takes place.

Here’s an example ~/.path file that adds /usr/local/bin to the $PATH:

export PATH="/usr/local/bin:$PATH"

If ~/.extra exists, it will be sourced along with the other files. You can use this to add a few custom commands without the need to fork this entire repository, or to add commands you don’t want to commit to a public repository.

My ~/.extra looks something like this:

# Git credentials
# Not in the repository, to prevent people from accidentally committing under my name
GIT_AUTHOR_NAME="Mathias Bynens"
GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME"
git config --global user.name "$GIT_AUTHOR_NAME"
GIT_AUTHOR_EMAIL="[email protected]"
GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"
git config --global user.email "$GIT_AUTHOR_EMAIL"

You could also use ~/.extra to override settings, functions and aliases from my dotfiles repository. It’s probably better to fork this repository instead, though.

When setting up a new Mac, you may want to set some sensible OS X defaults:

./.osx

When setting up a new Mac, you may want to install some common Homebrew formulae (after installing Homebrew, of course):

./brew.sh
