Ignore a File in Git Without Editing .gitignore

#git #vscode #tooling #programming

I work across multiple repositories. When you're juggling that many repos, it's easy to lose track of which one you're in. I kept finding myself squinting at the repo name in VS Code to make sure I wasn't about to make changes in the wrong project.

That's when I discovered Peacock, a VS Code extension that lets you change the editor color based on the project. A tiny visual cue, but a huge time-saver when you're context-switching all day.

The problem

The problem? One of our repos doesn't ignore the .vscode/settings.json file. So every time I tweaked Peacock's colors, Git would flag .vscode/settings.json as modified. Before committing, I had to manually stash or reset those changes so I wouldn't accidentally push them upstream.

I didn't want to touch .gitignore since teammates rely on committing shared project settings. What I needed was a way for Git to quietly ignore my tweaks without disrupting the repo for everyone else.

The Command That Saved My Sanity

After some digging, I learned about a neat trick:

# Tell Git to ignore local changes to this file
git update-index --skip-worktree .vscode/settings.json

From that point on, Git acted like the file was untouched, even if I completely changed the colors inside it. When I rangit status, nothing showed up. No more accidental commits, no more manual cleanup before pushing.

And if I ever need Git to notice changes again:

git update-index --no-skip-worktree .vscode/settings.json

When to Use It
Use --skip-worktree When:

The repo includes files that should be tracked, but your local edits aren't relevant to anyone else (like editor configs, test configs, or local scripts).
You want to keep your workflow smooth without constantly cleaning up changes before commits.

Avoid it when:

You need to collaborate on that file with your team.
Forgetting about the "skip" could cause important updates to be missed.

Final Thoughts
Peacock solved my repo-switching confusion. And git update-index --skip-worktree solved the annoying "settings file keeps showing up in git status" problem. Together, they've made my day-to-day dev flow smoother.
