If you ever wondered, why you can't add a file to git that you just created, it is probably somewhere ignored in a .gitignore file. But from what file and through which rule exactly? Luckily, it is possible to check that with git check-ignore.
The usage is quite straight forward. You pass it the path to a file. The command outputs the path if it is ignored.
> git check-ignore <pathname>
> git check-ignore -v <pathname>
If you use the verbose option -v, the command will additionally output, the exclude pattern that matched the path as well as the .gitignore file and the exact line number.
> git check-ignore -v .vscode/settings.json
.gitignore:4:.vscode .vscode/settings.json
