Using commands within bash script

Shell Programming and Scripting
1

The purpose of enclosed script is to execute selected command and output success or failure in whiptail msgBox

Works as expected when command returns zero to msgBox.

I cannot figure out how to continue / automate my script when command expects reply to continue / terminate. I am doing it manually in terminal by keying "q".

Basically

how do I detect in my script that the command requires response continue / return "control " back to scrip

and how do I insert "q" into my script?

PS I have deleted commented out code so the line numbers are NOT is sequence.


                         while read choice
  199  do
 204  $choice  #execute command  
 211 exitstatus=$?
 212  if [ $exitstatus = 0 ]; then
         msgDialog
  220 ((counter++))
  221  else
  222         echo "Exit status failed "
        fi

232  done < results

The break command is used to leave a loop eg:

while read choice
do
  $choice  #execute command  
  exitstatus=$?
  if [ $exitstatus = 0 ]; then
         msgDialog
        ((counter++))
  else
      echo "Exit status failed "
      break  # Leave the while loop
  fi
done < results

# Execution will resume here if end of results file reached or break statement above is triggered

I am sorry, that is not what I asked for.
Maybe this will clarify my request.

Here is a sample of one of the command outputs currently send to terminal and to get back to my script I have to use keyboard and type "q".
I would like to "automate" this outwit user interaction.

I am currently trying to redirect the command output back to my scrip and maybe I won't need this keyboard interaction.

Here is the solution , outputs the entire file to "script window ", text can be scrolled and the display can be terminated using standard "buttons"

inputBox(){
  37  HOSTNAME=$(\
  38  whiptail \
  39  --scrolltext \
  40  --title "Test input /text box " \
  41  --textbox /dev/stdin 20 80 <<<$($choice) \
  42 3>&1 1>&2 2>&3)
  43  
  44 }
