    # Bash getopt long options with values usage example

    ```sh
    #!/bin/bash -e
    # default args
    TEST_MODE=FALSE
    ENDPOINT_HOSTNAME=""
    AUX=""
    # getopt args
    options=$(getopt -o THPSA: --long test,host,check_prefix,check_suffix,handlers: --name "$0" -- "$@")

    FLAG_LIST=(
    "test"
    )

    ARGUMENT_LIST=(
    "endpoint"
    "argaux"
    )

    # read arguments
    opts=$(getopt \
    --longoptions "$(printf "%s," "${FLAG_LIST[@]}"),$(printf "%s:," "${ARGUMENT_LIST[@]}")" \
    --name "$(basename "$0")" \
    --options "" \
    -- "$@"
    )

    eval set --$opts

    while [[ $# -gt 0 ]]; do
    case "$1" in
    --test)
    TEST_MODE=TRUE
    shift;
    ;;
    --endpoint)
    ENDPOINT_HOSTNAME=$2
    shift 2
    ;;
    --argaux)
    AUX=$2
    shift 2
    ;;
    esac
    done

    echo TEST_MODE=$TEST_MODE
    echo ENDPOINT_HOSTNAME=$ENDPOINT_HOSTNAME
    echo AUX=$AUX
    # getopt args END
    ```



    **Note:** The `eval` in `eval set --$opts` is required as arguments returned by `getopt` are quoted.

    ## Example

    ```sh
    $ ./getopt.sh --test --endpoint "apple.com" --argaux "xyz"
    ```
