Load local environment variable files into current scope of terminal session, if any. Just paste to your `.bash_rc/profile`

.bash_profile

env_file_names=(
    './.env'
    './.env.local'
)
for file in ${env_file_names[*]}
do
    if [ -f "${file}" ]; then
        echo "Found local environment file: $file"
        echo "Loading..."
        . $file
    fi
done
