Bash Whiptail ping progress bar

Question

我正在尝试使用Whippail制作一个进度条，该进度条可以正确跟踪wget ping的进度。

我的目标是创建一个脚本，通过对google.com进行ping来测试你的互联网，当这种情况发生时，它会向你显示使用whiptail的进度，然后如果你上网了，它会给你发送一个消息框，否则它会显示一个"是"或"否"whiptail，询问你是否继续。

我目前的尝试：

    #!/bin/bash
    #Make ping and display proces
        #Progres bar GUI using whiptail(Native Gui)
        while true do
            # Check internet status, ping google.com
            wget -q --tries=20  --timeout=10 --spider http://google.com
        done| whiptail --title "Internet Validation" --gauge "${ping}" 6 60 0

    #If for validating Internet conexion
    if [ $? -eq 0 ]; then
        #If succes int variable change to Online 
        int="Online"
        #And Whiptail GUI disaply confimacion box
        whiptail --title "Succes" --msgbox "Internet Status: $int. Choose Ok to continue." 10 60
    #Internet validation opcion for when there is not internet
    else
        #Int Variable change to Offlien
        int="Offline"
        #Whiptail display Internet Status: Offline and ask if it whants to continue
        if (whiptail --title "Conexion Error" --yesno "Internet Status: $int, Continue?" 10 60) then
            #Function to install Nos Software
            $(function)
        else
            #Whiptail display installetion cancel
            whiptail --title "Installation" --msgbox "The Installation has been cancel." 10 60
        fi
    fi
    #Save in logfile Status of internet
    echo "`date -u` 'Internet Status: $int'" >> logfile.txt
