Pretty good first try.

Code:
#!/bin/bash
secretname=secret
name=noname
echo "try to guess the password."
TRY=0
echo
until [ "$name" = "$secretname" ] || [ "$TRY" -ge 5 ]
do
        echo -n "your guess: "
        read name
        ((TRY++))
done

if [ "$name" = "$secretname" ]
then
        echo "You guessed!"
else
        echo "Fail"
fi
