"You must type a file name" error thrown, when I create a .gitignore file on Windows

小开

Windows Explorer doesn't allow you to create files that consist essentially of a file extension only. This is because Windows Explorer has the option to hide file extensions, leaving you with a file you cannot see (see Why doesn’t Explorer let you create a file whose name begins with a dot?). This is not a restriction of Windows itself, or the file system in use, though.

To create a file named .gitignore, you will have to use another tool to create it. A common solution is to create a text file (e.g. test.txt), open it in Notepad, and select Save As... to rename the file to .gitignore.

The Windows command interpreter also allows you to create files without imposing the additional restrictions of Windows Explorer. A more direct solution would then be to create the file from the command line. This can be done using the following command:

copy NUL .gitignore

Note: When dealing with files that don't have a name, it's helpful to disable the option "Hide extensions for known file types" in Windows Explorer. Otherwise Windows Explorer might show files with no names, or hide them altogether.

最佳答案

In the File Explorer, the trick is to call your file .gitignore. and it will remove the ending .

A strange behavior but, hey!, it works 😅

Or create it from a text editor...

In cmd, just type

echo. 2>.name_you_want

or

. 2>.name_you_want

to create a file.

If creating a directory, just type

mkdir .folder_name_you_want

Use command line instead.
I was also having the same error. The problem was . at the start of file or folder name.
So I created it by command line.

You can do this with command prompt for folder creation:

mkdir .folder_name
