First, to check what files are you actually tracking
> git ls-tree --name-only --full-tree -r HEAD
Let say that you found unwanted files in a directory like cache/ so, it's safer to target that directory instead of all of your files.
So instead of:
> git rm -r --cached .
It's safer to target the unwanted file or directory:
> git rm -r --cached cache/
Then proceed to add all changes:
> git add .
and commit
> git commit -m ".gitignore is now working"
list up and sorting file(object) size in git / command
use following cmd:
> git rev-list --objects --all | git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' | sed -n 's/^blob //p' | sort --numeric-sort --key=2 | cut -c 1-12,41- | $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest
