Why do .env files exist?

Lately I've seen a lot of projects use .env files to store application configuration, files which look something like this:

FOO=bar
Bar=baz

Prebase

git-prebase improves on 'git rebase -i' by adding information per commit regarding which files it touched.

• Each file gets an alpha-numeric identifier at a particular column, a list of which appears below the commit list. (The identifiers wrap around after the 62nd file)
• Commits can be moved up and down safely (without conflicts) as long as their columns don't clash (they did not touch the same file).

Installation

Add the executable to your path and git will automatically expose it as

lttlrck

git branch -m old_branch new_branch         # Rename branch locally    
git push origin :old_branch                 # Delete the old branch    
git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote
