.gitignore only on local

Question

I would like to know how to gitignore files but only on local, without pushing it (because the other people working on the project should not get this update of gitignore of files I added there.

To be simple, after a git status I only have :

modified:   .gitignore 

because I added my files to ignore to my gitignore but well now I want the line above gone without pushing it.

Answer 1

For local ignores you should use the .git/info/exclude file, not .gitignore:

Patterns which are specific to a particular repository but which do not need to be shared with other related repositories (e.g., auxiliary files that live inside the repository but are specific to one user’s workflow) should go into the $GIT_DIR/info/exclude file.

The two files accept the same format.

Answer 2

Gitignore file should be committed because in most cases what you ignore would be ignored by other developers in the team too.

But if you absolutely need to exclude it from being tracked for local changes, you could do the following:

git update-index --assume-unchanged .gitignore

This will make it "disappear" from the modified list. Though if someone else changes it, you will not get the changes on pulling. You'll then need to do the below to bring it back to tracked list and do a pull again:

git update-index --no-assume-unchanged .gitignore
