If you’re using Windows, it will not let you create a file without a filename in Windows Explorer. It will give you the error “You must type a file name” if you try to rename a text file as .gitignore
To get around this, I used the following steps.
- Create the text file gitignore.txt
- Open it in a text editor and add your rules, then save and close
- Hold Shift, right click the folder you’re in, and then select Open command window here
- Then rename the file in the command line, with
ren gitignore.txt .gitignore
Alternatively, HenningCash suggests in the comments:
You can get around this Windows Explorer error by appending a dot to
the filename without an extension:.gitignore.
. It will be automatically
changed to.gitignore
