Functions

func Getenv

func Getenv(primary string, legacy ...string) string

Getenv returns the value of the primary environment variable. If the primary is empty or unset, it tries each legacy alias in order and returns the first non-empty value found. Returns "" if none are set.

func Unsetenv

func Unsetenv(key string) error

Unsetenv removes the named environment variable from the environment. It is a thin wrapper around os.Unsetenv that returns any error.
