github - Something like gitignore but not git ignore

Question

I want to ignore a file containing database-passwords and such. I asked a friend who set up the git if I could us gitignore. He said "no, because there is already a file with dummy data in the repository, there is another function that you should use, I don't remember what it's called, google it!"

I tried googleing, but given the information it's pretty tricky, does anyone know what function he is talking about?

Answer 1

If you add the file to .git/info/exclude - it will ignored, and this exclude file is local to your repository and will not be available to others.
