title: bash: read command is ignored in the loop
body: <p>I'm using a little code to check if some files match with each other or not then prompt a question to the user and take appropriate actions according to the user response. However, bash completely ignores my read command!</p>
  
  <pre><code>declare -i int
  int=1
  find ./1 -name '*.xyz' | while read FILENAME
  do
  find . -name '*.xyz' | while read FILENAME2
  do
      if [ $FILENAME != $FILENAME2 ]; then
          if [ $(dirname "${FILENAME}") != $(dirname "${FILENAME2}") ]; then
              if [ $(basename "${FILENAME}") == $(basename "${FILENAME2}") ]; then
                  int=int+1
                  if cmp -s "$FILENAME" "$FILENAME2" ; then
                      echo "Match", "$FILENAME", "$FILENAME2", "$int"
                  else
                      # echo "No Match", "$FILENAME", "$FILENAME2", "$int"
                      read -p "No match modify? (y/n)" d
                      echo "$d ";
                  fi
                  if [ "$int" -gt 44 ]; then
                      exit 1
                  fi
              fi
          fi
      fi
  done
  done

  <p>I am using osx.
  I have checked and a simple read command functions properly outside a loop on my terminal(iterm).</p>
