Git removing deleted files from tracking

Question

I'm new to Git so please bear with me. I initialized my repository and used 'git add .'

What happens if I delete a file and commit? Do I need to reuse 'git add .'? How do I ensure that when I push to master on github, the deleted file won't be there?

Answer 1

Use git rm to delete a file and make Git recognize the deletion.

git rm path/to/file
git commit
git push
