If you have some files that you need to have in your repo but don’t need to have updates, git allows it :

git update-index --skip-worktree <FILES>

Then a “git status” won’t show those files until you do :

git update-index --no-skip-worktree <FILES>

To show the skipped files :

git ls-files -v . | grep ^S

–skip-worktree is a better solution than –assume-unchanged because status will not get lost once an upstream change is pulled.
