case statement

Hi, would anyone know whether I could check to see whether any input has been entered via a case statment ?

echo "type"
read TYPE

case $TYPE in
[-z)echo "type"
read TYPE ;;
*) echo "YES YES" ;;

esac

I would like to check if nything has been entered but using a case statement.

Thank you

read waits for input, so if you've reached the case statement you *do* have input, thopugh it may have just been the ENTER key. You can check first for a null string as input:

Code:

case $TYPE in
  "") echo "No" ; exit 0 ;;
   *) echo "Yes" ;;
esac
