有没有无效的Linux文件名？ [英] Are there any invalid linux filenames?

问题描述

如果我想创建一个保证不能表示文件名的字符串，我可以在Windows中添加下列其中一个字符：

  \ /：*？ | < > 
  

  this-is-a-filename.png 
 
？this-is-not.png 
  

有什么办法可以在Linux上将字符串识别为不可能是文件？

解决方案

除了'/'和'\0'之外，几乎没有任何限制，您可以使用任何东西然而，有些人认为这不是个好主意非常灵活。

If I wanted to create a string which is guaranteed not to represent a filename, I could put one of the following characters in it on Windows:

\ / : * ? | < >

e.g.

this-is-a-filename.png

?this-is-not.png

Is there any way to identify a string as 'not possibly a file' on Linux?

解决方案

There are almost no restrictions - apart from '/' and '\0', you're allowed to use anything. However, some people think it's not a good idea to allow this much flexibility.
