Advanced Git Version Control: Glossary

Git version control records text-based differences between files.

Each git commit records a change relative to the previous state of the documents.

Git has a range of functionality that allows users to manage the changes they make.

This complex functionality is especially useful when collaborating on projects with others

A branch represents an independent line of development.

git branch creates a new pointer to the current state of the repository and allows you to make subsequent changes from that state.

Subsequent changes are considered to belong to that branch.

The final commit on a given branch is its HEAD.

The git remote command allows us to create, view and delete connections to other repositories.

Remote connections are like bookmarks to other repositories.

Other git commands (git fetch, git push, git pull) use these bookmarks to carry out their syncing responsibilities.

git reset rolls back the commits and leaves the changes in the files

git reset --hard roll back and delete all changes

git reset does alter the history of the project.

You should use git reset to undo local changes that have not been pushed to a remote repository.

git revert undoes a commit by creating a new commit.

git revert should be used to undo changes on a public branch or changes that have already been pushed remotely.

git revert only backs out a single commit or a range of commits.

git merge --no-ff is the best way to merge changes

git merge --ff-only is a good way to pull down changes from remote

git tag allows us to mark a point we can return to.

A tag is tied to a commit.

A branching model is a pre-agreed way of merging branches into the main branch.

A branching model is needed when multiple contributors are making changes to a single project.
