for example:

    while [[ $# -gt 0 ]]; do
        case "$1" in
            --restore)
                RESTORE=true

            *)
                log_erro "Unknown option: $1"
                usage
                return 1
                ;;
        esac
    done

This is very similar for bash scripting needed to handle the options.

This plugin should ignore the mismatch in the switch case of bash (maybe including other POSIX shell scripts language), which is leagal for them.
