You could use a tool like xdotool to send Ctrl-A (begin-of-line) Ctrl-K (delete-to-end-of-line) Return (to cleanup the line)

#!/bin/bash
trap "xdotool key Ctrl+A Ctrl+k Return" SIGINT;
unset command
while [ "$command" != "quit" ] ;do
    eval $command
    read -e -p "$USER - SHIELD: `pwd`> " command
  done
trap SIGINT

But I strongly invite you to rtfm... In searching for ``debug'' keyword...

man -Pless\ +/debug bash
