问题描述
我跑在Windows 7上这是在Cygwin下编译并通过了NUL作为一个输出文件名的程序。相反，SUP pressing输出它实际上创造了一个在当前目录下名为NUL文件。 （显然它希望的/ dev / null的，即使是在Windows）。现在我仍坚持这一NUL的文件，我不能删除！
I ran a program on Windows 7 that was compiled under Cygwin and passed "NUL" as an output file name. Instead of suppressing output it actually created a file named "NUL" in the current directory. (Apparently it expects "/dev/null", even on Windows.) Now I'm stuck with this "NUL" file that I cannot delete!
我已经尝试过：
- Windows资源管理器 - 错误：无效的MS-DOS功能（！是的，这是严重的它说什么）
- 使用德尔NUL命令提示符 - 错误：文件名，目录名或卷
标签语法不正确。 - 删除整个目录 - 同一交易只是删除文件
-
删除（）在C程序 - 也失败
- Windows Explorer - error: "Invalid MS-DOS function" (yes, that is seriously what it says!)
- Command prompt using "del NUL" - error: "The filename, directory name, or volumelabel syntax is incorrect."
- Deleting the entire directory - same deal as just deleting the file
remove()in a C program - also fails
如何才能摆脱这些文件NUL（我现在几个），总之在Cygwin下安装完整的Cygwin环境和编译C程序的办呢？
How can I get rid of these NUL files (I have several by now), short of installing the full Cygwin environment and compiling a C program under Cygwin to do it?
推荐答案
打开命令提示符，然后使用这些命令，先重命名，然后删除NUL文件：
Open a command prompt and use these commands to first rename and then delete the NUL file:
C:\> rename \\.\C:\..\NUL. deletefile.txt
C:\> del deletefile.txt
使用 \\\\。\\ preFIX讲述了高层次的文件I / O函数来传递文件名未解析到设备驱动程序 - 这样你就可以访问否则无效名称。
Using the \\.\ prefix tells the high-level file I/O functions to pass the filename unparsed to the device driver - this way you can access otherwise invalid names.
