How about

Code:
finger $Username >/dev/null 2>&1
if test "$?" != "0"
then
     echo user does not exist
fi

What does the F/dev/null 2>&1 Do?

>/dev/null means write stdout to /dev/null, the bit-bucket

2>&1 means put stderr in the same place as stdout

Who is the adminstrator for this system?

Another way:
Code:
userentry=$(getent passwd $username)
if [ $? -ne 0 ]; then
        echo "$username does not exist"
        exit 1
fi
/usr/bin/echo "${username}'s home directory is \c"
echo "$userentry" | cut -d: -f6
