Bash 脚本 - Wget 图形化下载进度

Question

我正在尝试将此代码从wget + zenity移植到wget + kdialog.
代码zenity：

#!/bin/bash

# Start wget | zenity
# Note the & at the end of the pipe, this allows the script to continue with wget running in the background

wget http://www.zezeniaonline.com/download/downloadlinux 2>&1 | sed -u 's/.* \([0-9]\+%\)\ \+\([0-9.]\+.\) \(.*\)/\1\n# Downloading at \2\/s, ETA \3/' | zenity --progress --title="Downloading File..." 

#Start a loop testing if zenity is running, and if not kill wget
RUNNING=0
while [ $RUNNING -eq 0 ]
do
if [ -z "$(pidof zenity)" ]
then
  pkill wget
  RUNNING=1
fi
done

Zenity 代码完美运行

我需要做同样的事情，但是使用kdialog. 我首先尝试使用以下代码：

#!/bin/bash

# Start wget | kdialog

wget http://www.zezeniaonline.com/download/downloadlinux 2>&1 | sed -u 's/.* \([0-9]\+%\)\ \+\([0-9.]\+.\) \(.*\)/\1\n# Downloading at \2\/s, ETA \3/' | kdialog --progressbar " " --title="Downloading File..." 

#Start a loop testing if zenity is running, and if not kill wget
RUNNING=0
while [ $RUNNING -eq 0 ]
do
if [ -z "$(pidof kdialog)" ]
then
  pkill wget
  RUNNING=1
fi
done

根本不起作用

#!/bin/bash 
# Start wget | kdialog

wget --progress=dot http://www.zezeniaonline.com/download/downloadlinux 2>&1 | fgrep --line-buffered '%' \ | sed -u -r 's:.* ([0-9]+)% .*:\1:' | kdialog --title "Installation" --progressbar " " &

#Start a loop testing if kdialog is running, and if not kill wget
RUNNING=0
while [ $RUNNING -eq 0 ]
do
if [ -z "$(pidof kdialog)" ]
then
  pkill wget
  RUNNING=1
fi
done

但出现以下错误。 是的，它正在下载，但是“kdialog”中的“进度”不是“进度”

这是我自己的解决方案，我在本页链接的网站上修改了一些旧教程：

这段代码将尝试下载我在 github 上的主存储库

    link="https://github.com/nowardev/kde-peace-settings/archive/master.zip" #my own github stuff 
    a=$(kdialog --progressbar "W-Get will  download: Nowardev GitHub Master stuff " 100);sleep 2
    qdbus $a  showCancelButton true

    while read line ;do
    read -r p t <<< "$line"
    echo $p 
    echo $t 
    qdbus $a Set org.kde.kdialog.ProgressDialog value $p

        while [[  $(qdbus  $a wasCancelled) != "false" ]] ; do
            echo "KILLING THE PROCESS AND KDIALOG"
            qdbus $a  org.kde.kdialog.ProgressDialog.close 

            exit
        done


qdbus $a org.kde.kdialog.ProgressDialog.setLabelText "W-Get will  download: Nowardev GitHub Master stuff  time left : $t" 


done< <(wget "$link" 2>&1 |mawk -W interactive '{ gsub(/\%/," "); print int($7)" "$9 }')
