Cleaning

Show informations about remote branches:

git remote show origin

Stop tracking deleted remote branches:

git remote prune origin --dry-run

Remote tracking

Verify origin and upstream setup:

git remote -v

If upstream is missing, setup:

git remote add upstream [email protected]:some-gatekeeper-maintainer/some-project.git

Collect changes of upstream repository:

git fetch upstream

Checkout main branch (master):

git checkout master

And continue usual workflow:

git pull upstream master || $ git merge upstream/master || $ git rebase upstream/master

Lost and found

Look to log for what you lost:

git reflog

Create new branch from what you found:

git checkout -b branch-name 70b3696

Unstage all local changes

To keep changes:

git reset HEAD

To remove everything not commited permanently:

git reset --hard HEAD

To reset changes to specific origin branch:

git fetch origin
git reset --hard origin/master

remove cached files if change in .gitignore is not taken into account

git rm -r --cached .
git add .

change info about previous commits

start interactive rebase as many commits backward as you need

git rebase -i HEAD~8

and in message alter details of specific commits with command on next line after wanted commit pick

pick a37d264 PHPSPEC-1 Install
