Ich hab zwar noch nichts mit dialog gemacht, aber es liegt ein sample
file dabei:

---------------------------------------------------------------------

#!/bin/sh
DIALOG=${DIALOG=../src/dialog}

$DIALOG --title "YES/NO BOX" --clear \
        --yesno "Hi, this is a yes/no dialog box. You can use this to ask \
                 questions that have an answer of either yes or no. \
                 BTW, do you notice that long lines will be automatically \
                 wrapped around so that they can fit in the box? You can \
                 also control line breaking explicitly by inserting \
                 'backslash n' at any place you like, but in this case, \
                 auto wrap around will be disabled and you will have to \
                 control line breaking yourself." 15 61

case $? in
  0)
    echo "Yes chosen.";;
  1)
    echo "No chosen.";;
  255)
    echo "ESC pressed.";;
esac

Sieht nicht so kompliziert aus oder?
