Ignoring a file in a given git repository… just for you
Sometimes I want to be able to have a file hanging around in a local version of a git repository that I’ve checked out. For example, I often create a shell.nix that specifies build dependencies without installing them system-wide. Here’s how I add a shell.nix to the root of a repository while also instructing git to ignore it – and without adding or making a modification to `.gitignore:
$ cat >> .git/info/exclude
