Remove ;from the end of your script lines.
;从脚本行的末尾删除。
This doesn't happen in my bash, so I'm not sure what exactly is wrong, but my guess is this:
这不会发生在我的 bash 中，所以我不确定到底出了什么问题，但我的猜测是：
;is a separator of commands. Since your last command ends in ;, your bash probably expects another command after. Since the script finishes, though, it reads an empty command, which it can't execute.
;是命令的分隔符。由于您的最后一个命令以 结尾;，因此您的 bash 可能需要另一个命令。但是，由于脚本完成后，它会读取一个无法执行的空命令。

My guess is that you have unprintable control characters in the file, or it has \r\n(CRLF) line endings (dos/windows mode).
我的猜测是文件中有不可打印的控制字符，或者它有\r\n(CRLF) 行结尾（dos/windows 模式）。
Try checking it with these commands:
尝试使用以下命令检查它：
