git clone [URL], which clones, or duplicates, a git repository from an external URL. git add [file], which adds a file to git's working directory (files about to be committed). git commit -m [commit message], which commits the files from the current working directory (so they are now part of the repository's history). A .gitignore file may be ...
Child branches are branches that have a parent; a branch without a parent is referred to as the trunk or the mainline. [1] The trunk is also sometimes loosely referred to as HEAD, but properly head refers not to a branch, but to the most recent commit on a given branch, and both the trunk and each named branch has its own head.
commit: Record changes in the repository; revert: Restore working copy file from repository; generate bundle file: Create a file that contains a compressed set of changes to a given repository; rebase: Forward-port local commits to the updated upstream head
The repository keeps track of the files in the project, which is represented as a graph. A distributed version control system is made up of central and branch repositories. A central repository exists on the server. To make changes to it, a developer first works on a branch repository, and proceeds to commit the change to the former.
Most version control systems allow multiple developers to edit the same file at the same time. The first developer to "check in" changes to the central repository always succeeds. The system may provide facilities to merge further changes into the central repository, and preserve the changes from the first developer when other developers check in.
When making a code change, a developer creates a branch that is a copy of the current codebase. As other changes are committed to the repository, this copy diverges from the latest version. The longer development continues on a branch without merging to the integration branch, the greater the risk of multiple integration conflicts [13] and ...
To update is to acquire or merge the changes in the repository with the working copy. CVS uses a client–server architecture: a server stores the current version(s) of a project and its history, and clients connect to the server in order to "check out" a complete copy of the project, work on this copy and then later "check in" their changes.
A software repository, or repo for short, is a storage location for software packages. Often a table of contents is also stored, along with metadata. A software repository is typically managed by source or version control, or repository managers. Package managers allow automatically installing and updating repositories, sometimes called "packages".
