在執行腳本時，出現了: invalid option 錯誤

最后在stackoveflow上找到了答案

You script probably has characters in it that you cannot see. Perhaps it was copy/pasted using the wrong character set translation or is in DOS format. In the case of the latter you can use the tofrodos or dos2unix package to correct.


In either case you could pull it up in ‘vi’ or another application which will usually show weird characters like ^@ or ^M. You could try cat -v filename which might help see these oddities. Push comes to shove try hexdump (or hd, or od).

原來是因為使用window 復制黏貼該文件時，文件的格式發生了變化。

解決方案：在ubuntu上使用dos2unix命令去除格式即可
