dunno what shell you're using.. I use ksh and would do something like-

Code:
echo "username : "
read username
echo "password :"
read pwd

if [[ ${#pwd} -lt 1 ]]  # checks if the length of $pwd is greater than 1
then exit 1                # if it's not, then exit
fi                             # or you could just to if [[ $pwd = "" ]] or                                                         
                               # something... i left my unix book at work!
