It looks like there is some "junk" characters after your folder name (namely, \r). To be sure, type cat -A scriptname.shand check if you can see some weird characters in the end of the lines. If so, I think the easiest thing for you (since you have few lines) is to manually delete the ending of those lines and re-type again. (I'm talking about the last two or three characters only)
Type cat -A scriptname.shand see if the characters disappeared. If so, you should be good to go with your code.
看起来您的文件夹名称（即\r）后面有一些“垃圾”字符。可以肯定的是，键入cat -A scriptname.sh并检查是否可以在行尾看到一些奇怪的字符。如果是这样，我认为对您来说最简单的事情（因为您只有几行）是手动删除这些行的结尾并再次重新键入。（我只说最后两三个字符）键入cat -A scriptname.sh并查看字符是否消失。如果是这样，您应该很好地使用您的代码。
