Remotes

git remote -v

shows what remotes are configured and their urls. good for sanity checking.

git remote add origin https://github.com/you/repo.git

connects a local repo to a remote. you'd do this after git init on a fresh project.

git fetch

downloads changes from remote but doesn't apply them. safe — nothing in your working tree changes.

git pull --rebase

fetches and rebases your local commits on top. cleaner than a regular git pull which creates a merge commit for no real reason.

git push

pushes your current branch to remote. first time on a new branch you'll need:

git push -u origin feature/my-thing

the -u sets upstream tracking so future git push and git pull just work.

git push -f

force push. rewrites the remote branch. only do this on your own feature branches, never on shared branches. if you've rebased or amended commits that were already pushed, you'll need this.
