How To Install direnv on Kali Linux

Introduction

What is direnv

direnv is:

direnv is an environment variable manager for your shell. It knows how to hook into bash, zsh and fish shell to load or unload environment variables depending on your current directory. This allows one to have project-specific environment variables and not clutter the “~/.profile” file.

Before each prompt it checks for the existence of an “.envrc” file in the current and parent directories. If the file exists, it is loaded into a bash sub-shell and all exported variables are then captured by direnv and then made available to your shell.
