Yes with bash.. This will change directory to the specified directory as normal and if a .env file exists there it will source it. If you add this snippet to your users .bashrc and source it.

function cd() { new_directory="$*"; if [ $# -eq 0 ]; then new_directory=${HOME}; fi; builtin cd "${new_directory}" if [ -f .env ]; then source .env fi } 

If you want load .env while opening a new tab

function loadenv() { if [ -f .env ]; then source .env fi } loadenv function cd() { builtin cd $@ loadenv }
