Source & export .env into your shell.
Adds export statements to each line of a dotenv .env file, for defining
any variables therein in your shell.
npm i -g dotenv-export
source <(dotenv-export)
Or you can use a custom file name instead of the default .env, e.g., .env.test:
source <(dotenv-export .env.test)
To export multiline environment variables (as supported in the dotenv package), use the literal characters \n in your variable:
MULTILINE_VAR="I\nlike\ntrains"
And run the following command to convert the \n characters to actual new lines:
source <(dotenv-export | sed 's/\\n/\n/g')
