shell命令为啥出现': not a valid identifierON错误

[风空]

#!/bin/bash
# Author : mozhiyan
# Copyright (c) http://see.xidian.edu.cn/cpp/linux/
# Script follows here:
echo "What is your name?"
read PERSON
echo "Hello, $PERSON"

上面是我的代码，下面是我执行时候的错误

$ sh d.sh
What is your name?
zhamngzh
': not a valid identifierON
Hello,


为啥，高手请指导下

可能你在某个地方定义了一个PERS变量。 echo "Hello, $PERSON"中的PERSON用花括号括起来应该可以解决问题 echo "Hello, ${PERSON}"
