Remove Commited File from Version Control

you have some (log) files under version control. you may wanna update .gitignore, but these already commited Files do not get removed from Version Control automatically

echo 'container/prod/kuma/data/kuma.db-shm' >> .gitignore
git rm --cached container/prod/kuma/data/kuma.db-shm
git status

-> –cached removes the file from the repository, but keep it locally

List Files which are excluded via .gitignore

git ls-files --other --ignored --exclude-standard
