Git allows the commits saved in different versions of the code to be easily merged (combined) back together without you needing to manually copy and paste different pieces of the code. Git supports having multiple different versions of your work that all live side by side (in what are called branches), whether those versions are created by one person or many collaborators. You can push (upload) commits to, and pull (download) commits from, a remote repository to keep everything in sync. Typically this will be a central version of the repository that all local copies on your various development machines point to. Committing a set of changes creates a вЂњsnapshotвЂќ of what that work looks like at the time-itвЂ™s like saving the files, but more so.ДЄ link to a copy of this same repository on a different machine. This extra tracking information allows you to see when, why, and by whom changes were made to a given file. If you want to sound cool and in-the-know, call a project folder a вЂњrepo.вЂќДЄ set of file versions that have been added to the repository (saved in the database), along with the name of the person who did the commit, a message describing the commit, and a timestamp. Read this section carefully, and come back to it if you forget what these terms mean.ДЄ database containing all the committed versions of all your files, along with some additional metadata, stored in a hidden subdirectory named. To understand how git works, you need to understand its core concepts. There are a number of different version control systems in the world, but git is the de facto standard-particularly when used in combination with the cloud-based service GitHub. Git helps the team coordinate all these changes, and provides a record so that anyone can see how a given file ended up the way it did.

Almost all professional development work is done in teams, which involves multiple people working on the same set of files at the same time. This is often helpful in programming, especially if you embark on making a massive set of changes, only to discover part way through that those changes were a bad idea (we speak from experience here рџ± ).Д«ut where git really comes in handy is in team development. Like Dropbox and Google Docs, git can show you all previous versions of a file and can quickly rollback to one of those previous versions. This means it can easily and automatically combine changes from multiple people, and gives you very precise information what what lines of code changes. You typically need to write some code, save it, test it, debug, make some fixes, and test again before youвЂ™re ready to save a new version.ДЇor text files (which almost all programming files are), git tracks changes line-by-line. That approach works fine for word-processing documents, but not for programming files. Git doesnвЂ™t save a new version every time you save a file to disk. New versions of your files must be explicitly вЂњcommittedвЂќ when they are ready. However, systems like git different from Dropbox in a couple of key ways: Version control systems work a lot like Dropbox or Google Docs: they allow multiple people to work on the same files at the same time, to view and вЂњroll backвЂќ to previous versions.

Eric Raymond defines version control asДЄ version control system (VCS) is a tool for managing a collection of program code that provides you with three important capabilities: reversibility, concurrency, and annotation. Git is an example of a version control system.
