如何在不删除这些文件的情况下切换到忽略文件的git分支？

Question

I have branch master that ignores .idea in its .gitignore . From that, I created branch noIgnore that has no .gitignore .

I found that checkout master deletes .idea .

That's not the behavior I want. I want to keep .idea , just not track it, not on master . How do I do that?

Answer 1

You could stop tracking changes for a file in repo

git update-index --skip-worktree .idea

Since you're tracking it in the other branch, then when you make changes you'll want to start tracking changes again

git update-index --no-skip-worktree .idea

When you get tired of doing this manually, you could create a post-checkout hook if on master, stop tracking, else start tracking.

Answer 2

It removes .idea because that's what checkout does, it checks out master where there's no .idea. Try to add --no-track to your command.
