How to ignore file update in GIT?

Question

linux

There is an example.txt file (for example). The file is necessary and there can be no question of any .gitignore . There is a remote repository for tests (test server) where you need to change a couple of lines of the file. How to make it so that when pushing, etc., the repository ignores any changes to this file - that is, so that after each commit or push I don’t have to merge manually. How to do it?

Answer 1

git update-index --assume-unchanged FILENAME

Answer 2

The .gitignore file at the root of the turnip
AND do git add -p and ignore changes to the file
