Bash路径包含空间，没有这样的文件或目录 [英] Bash path contained space no such file or directory

问题描述

根据此问题如何使用空白?我已经声明了这样的目录路径:

As per this question How to input a path with a white space? I have declared a directory path like that:

startup='/cygdrive/c/Users/Me/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup';我试图将路径换成双引号，但它也不起作用.

startup='/cygdrive/c/Users/Me/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup'; I tried to wrap the path in to double quotes but it is not working either.

但是由于某些原因，当我键入$startup时出现错误:

But for some reason when I am typing $startup I am getting an error:

$ $startup
bash: /cygdrive/c/Users/Alex/AppData/Roaming/Microsoft/Windows/Start: No such file or directory

您将如何解决?

推荐答案

用引号将变量引起来:

$ "$startup"

为了安全起见，应始终引用变量.您可以参考此页面以获取更多详细信息.

You should always quote variables to be safe. You can refer to this page for more details.

如第一段所述:在引用变量时，通常建议将其名称括在双引号中.这样可以防止重新解释带引号的字符串中的所有特殊字符-除$，`(反引号)和\(转义)."

您还可以参考此页面，其中指出:基本的经验法则是您应该对每个扩展名都加双引号.这样可以防止不必要的单词拆分和乱码.如有疑问，请引用.

You can also refer to this page which states: The basic rule of thumb is that you should double-quote every expansion. This prevents unwanted word splitting and globbing. When in doubt, quote it.
