I am coding in bash ,using Ubuntu 18.04, and I am playing around with kdialog. I made a simple magic eight ball themed program and I am unable to close the input box and exit the program, instead I get stuck in a loop. This code was originally made in BASH dialog and I decided to change it to kdialog. Any help would be greatly appreciated. It is something simple that I am overlooking.

#!/bin/bash

#version 3



OUTPUT="TEMP.txt"

>$OUTPUT



while [ true ]

do



shuffle() {

   local i tmp size max rand

   size=${#array[*]}

   max=$(( 32768 / size * size ))



   for ((i=size-1; i>0; i--)); 

    do

      while (( (rand=$RANDOM) >= max )); 

    do :; 

    done

      rand=$(( rand % (i+1) ))

      tmp=${array[i]} 

      array[i]=${array[rand]} 

      array[rand]=$tmp

   done

}



array=( 'It Is Certain' 

'Without A Doubt' 

'Maybe' 

'Signs Point To Yes' 

'Most Likely'

'As I See It, Yes'

'Ask Again Later'

'Concentrate And Ask Again'

'HAHAH No..'

'Ask Again'

'Have Faith In Yourself'

'Very Doubtful'

'Outlook Not So Good'

'My Sources Say No'

'Unknown At This Time' 

'Could Happen Any Moment Now'

'Is That A Joke?'

'Unlikely' )



shuffle



function sayhello(){

    local n=${array[@]}-""

    #display it 

kdialog --msgbox "This Is What I See:  ${array}"

 #--clear --msgbox "${array}" 8 41

}







# show an inputbox

kdialog --title "Welcome " 

--inputbox "Ask and you shall recieve great fortune: " #8 60 



function think_tank(){

progress=$(kdialog --progressbar "hmmm Let Me Think..." 4);

sleep 1;

qdbus $progress Set "" value 1 > /dev/null;

sleep 1;

qdbus $progress Set "" value 2 > /dev/null;

sleep 1;

qdbus $progress Set "" value 3 > /dev/null;

sleep 1;

qdbus $progress Set "" value 4 > /dev/null;

sleep 1;

qdbus $progress close > /dev/null;

sleep 1

#kdialog --title "This is a passive popup" --passivepopup 

#"It will disappear in about 10 seconds" 10



}

# get response

response=$? 



# get data stored in $OUPUT using input redirection

name=$(<$OUTPUT)



case $response in

  0) 

    think_tank

    sayhello ${array[@]}

    ;;

   1) 

    echo "Goodbye For Now." 

exit 0

;;  

  255) 

   echo "Goodbye For Now."

exit 0

;;

esac



#rm $OUTPUT

done

done

After some sleep I easily figured this issue out. I removed the case statement and used if statements instead. The program would not break out of the case statement due to a return 0 from kdialog's --msgbox.

#made some quick msgbox functions 

    if [ "$?" = 0 ]; 

    then

        think_tank #progress bar

        msg_box #results

    elif [ "$?" = 1 ]; 

    then

        goodbye #closing message box

    exit 0;

    else

        error #error message box

    exit 0;

    fi;
