where should I put .gitignore to affect all projects?

Question

where should I place a .gitignore file so that all my projects use those settings?

I tried various folders and I can only get it to work if I put it in my project folder, but then the settings (of course) only are applied to that project... not my other projects.

git include a "global" configuration option which can tell it to include the files you want to ignore always when you start a project. Example, if the compilation of your ignore files is called: ignore_global, you could do this;

git config --global core.excludesfile /path/to/your/ignore_global
