shell脚本的read -p写法

一个脚本sh02.sh是：
#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH
read -p "Please input your first name: " firstname
read -p "Please input your last name: " lastname
echo -e "\nYour full name is: $firstname $lastname
但执行时提示sh02.sh: -p: is not an identifier
我直接在unix中敲read -p "Please input your first name: " firstname没有问题，请问是脚本哪里不对？

另外，当仅执行echo -e "\nYour full name is: $firstname $lastname时显示一个：
-e
Your full name is: 
这里-e怎么会打印出呢？

谢谢！

小伙子，你最好貌似没有加引号吧，我的执行结果如下：
[root@node2 ~]# sh aaaaaa.sh 
Please input your first name: zhu
Please input your last name: ying

Your full name is: zhu ying

最后一行的行尾少了个双引号
什么系统？

test.sh

Assembly code

#!/bin/bash
for ((i=1;i<=3000))
do
    touch $i.txt
done

time ./test.sh
