linux - Bash Whiptail ping 进度条

Question

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

我的目标是创建一个脚本，通过对 google.com 执行 ping 命令来测试您的互联网，当发生这种情况时，它会使用 whiptail 向您显示进度，然后如果您可以上网，它会向您发送一个 msgbox，否则它将向您显示是或否的 whiptail，它会询问您是否要继续。

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
