Git branches are simply pointers pointing to a specific command. 

 

Branch early, and branch often.

 

rebase in git

 

HEAD - symbolic name for currently checked out commit. always points to the most recent commit. 

instead of checking out to a branch, you could check out towards specific commit. 

 

Caret(^) - travels to parent version

 

Tilde(~) - travles specific number of parents 

 

git branch -f master HEAD~3 = =        move master branch to head + 3

 

reversing changes in git::

git reset - works great in local repository, going back to rewrite history

 

git revert  - works great for remote repository, git revert creates a new commit of the previous version, allowing you to push to other checkouts. 

 

 

 

 

Above commands should cover 90% of vcs(version control system) while 10% will help in more flexible precise ways.

 

cherry-pick

 

git rebase -i HEAD~4, omit and pick 

use tag for version display
