expanding command line interface or linking to sister project

[mandric]

I think expanding the cli here or linking to a project written in go that uses this library to provide a little more cli utility would be very helpful and more complete.

I find the cli interface bit limited, for example I don't fine this functionality generally useful:

godotenv -f /path/to/something/.env,/another/path/.env fortune

something like a generic set/get of key/values like seems more useful:

godotenv set foo "$bar"  # updates ./.env by default

similar to the python cli dotenv:

$ dotenv 
Usage: dotenv [OPTIONS] COMMAND [ARGS]...

  This script is used to set, get or unset values from a .env file.

Options:
  -f, --file PATH                 Location of the .env file, defaults to .env
                                  file in current working directory.

  -q, --quote [always|never|auto]
                                  Whether to quote or not the variable values.
                                  Default mode is always. This does not affect
                                  parsing.

  -e, --export BOOLEAN            Whether to write the dot file as an
                                  executable bash script.

  --version                       Show the version and exit.
  --help                          Show this message and exit.

Commands:
  get    Retrieve the value for the given key.
  list   Display all the stored key/value.
  run    Run command with environment variables present.
  set    Store the given key/value.
  unset  Removes the given key.
