How to write a good commit message

Local branches

git checkout main then git branch -D <branchname> delete local branch
git checkout -b clean-branch-name origin/main create a clean branch from main
git branch -m old-branch-name new-branch-name rename a branch

Remote branches

Origins

git remote add origin <repository-url> add remote origin
git remote remove origin remove remote origin
git remote set-url origin url update remote origin
git remote -v view connected remote repositories

Pull and push

git pull origin main pull remote main branch into local branch
git push origin branchName push branch to the remote repo feature branch or
git push -u origin branchName push feature branch to the remote repo and set it as the upstream branch, then git push will push to that branch
git checkout -b new-branch origin/branchname checkout remote branch, good for testing PRs

Problems / Solutions

Wont push to a remote repo that has a README

git fetch --all
git rebase origin/main

Wont push because file is too large (remote hung up)

Increase file size limit to 1GB

git config http.postBuffer 1048576000

Merge conflicts

git pull origin main
git checkout feature-branch
git rebase main
 
# fix conflict
git add .
git rebase --continue
# repeat until conflicts are resolved
 
git push origin feature-branch --force
