Autoenv: Directory-based Environments

Magic per-project shell environments. Very pretentious.

Note: you should probably use `direnv <>`_ instead. It is higher quality, and maintained.

What is it?

If a directory contains a .env file, it will automatically be executed when you cd into it.

This is great for...

  • auto-activating virtualenvs
  • project-specific environment variables
  • making millions

You can also nest envs within each other. How awesome is that!?

When executing, autoenv, will walk up the directories until the mount point and execute all .env files beginning at the top.


Follow the white rabbit:

$ echo "echo 'whoa'" > project/.env
$ cd project


Install it easily:

Mac OS X Using Homebrew

$ brew install autoenv
$ echo "source $(brew --prefix autoenv)/" >> ~/.bash_profile

Using pip

$ pip install autoenv
$ echo "source `which`" >> ~/.bashrc

Using git

$ git clone git:// ~/.autoenv
$ echo 'source ~/.autoenv/' >> ~/.bashrc

Using AUR

Arch Linux users can install autoenv or autoenv-git with their favorite AUR helper.

You need to source in your bashrc afterwards:

$ echo 'source /usr/share/autoenv/' >> ~/.bashrc


Before sourcing, you can set the following variables:

  • AUTOENV_AUTH_FILE: Authorized env files, defaults to ~/.autoenv_authorized
  • AUTOENV_ENV_FILENAME: Name of the .env file, defaults to .env
  • AUTOENV_LOWER_FIRST: Set this variable to flip the order of .env files executed


autoenv is tested on:

  • bash
  • zsh
  • dash
  • fish is supported by autoenv_fish
  • more to come


Direnv is an excellent alternative to autoenv, and includes the ability to unset environment variables as well. It also supports the fish terminal.


Autoenv overrides cd. If you already do this, invoke autoenv_init within your custom cd after sourcing

Autoenv can be disabled via unset cd if you experience I/O issues with certain file systems, particularly those that are FUSE-based (such as smbnetfs).
