Loads the environment variables in a .env file (intended for bash) into the current terminal session.

README.md

For PowerShell on Windows 10.

By default this function attempts to locate a .env file in the current folder.
If the file is found, tries to load the environment variables set on it into the current terminal session.

Load-DotEnv

You can pass the path to any other file containing the variables you want to load as first argument.

Load-DotEnv ..\.env.production

If you want to automatically load the variables if a .env file exists after cding into a folder, you can put this command inside the prompt() function in your profile script.

The environment variables are expected to be written in format: export VARIABLE=value, where value can be surrounded by these quotation marks: ", ', and `.
