Bash Script - Progresso do Download Gráfico Wget

Question

Estou tentando portar esse código de wget + zenity para wget + kdialog .
O código com 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/.* \([0-9]\+%\)\ \+\([0-9.]\+.\) \(.*\)/\n# Downloading at \/s, ETA /' | 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

O Código Zenity Funciona perfeitamente

Euprecisofazeromesmo,mascomkdialog.Eutenteiprimeirocomoseguintecódigo:

#!/bin/bash#Startwget|kdialogwgethttp://www.zezeniaonline.com/download/downloadlinux2>&1|sed-u's/.*\([0-9]\+%\)\\+\([0-9.]\+.\)\(.*\)/\n#Downloadingat\/s,ETA/'|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

que não funcionam de todo

#!/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]+)% .*::' | 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

Mas os erros a seguir. Sim, seu download, mas o "progresso" não está "progredindo" no "kdialog"

Aqui está minha própria solução, modifiquei um pouco meu antigo tutorial no meu site linkado nesta página:

este código tentará baixar meu repositório principal no github

    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 }')

Estou tentando adaptar esse código-fonte, esse código funciona, bem, só preciso adaptar as partes que realmente preciso.
