您需要if以以下语句结尾fi：

if [ "$i" = "Tyler" ]
    then
        read -p "Hello Tyler. Please enter you password now:" b         

            if [ "$b" = "1234567890" ]
                    then
                        echo "You really are Tyler!! Prove it again!!"
                        su

            else
                echo "WRONG ANSWER!!"
            fi
fi

更新脚本（有效）

#!/bin/bash

clear

read -p "Please enter your name:" i

if [ "$i" = "Tyler" ]
    then
        read -p "Hello Tyler. Please enter you password now:" b         

            if [ "$b" = "1234567890" ]
                    then
                        echo "You really are Tyler!! Prove it again!!"
                        su

            else
                echo "WRONG ANSWER!!"
        fi
fi

if [ "$i" = "LouRae" ]
    then 
        read -p "Hey there beautiful. Please enter you password now:" b

            if [ "$b" = "123456789" ]
                    then
                        echo "You really are LouRae!! Prove it again!!"
                        su
            else
                        echo "WRONG ANSWER!!!"
        fi
fi

if [ "$i" = "Emma" ]
    then
        read -p "Hello Emma. Please enter you password now:" b

            if [ "$b" = "12345678" ]
                    then
                        echo "You really are Emma!! Prove it again!!"
                        su
            else
                        echo "WRONG ANSWER!!!"
        fi
fi
