What is GIT?
Gitis a scalable, fast and distributed revision control system with a usually rich command set that provides both high-level operations & full access to internals.
Git stores and deals with the information much differently than these other version control systems, even though the user interface is fairly similar, and understanding those differences will help prevent you from becoming confused while using it.
The major difference between git and other Version Control System (VCS) is the way Git thinks about its data. Accordingly, some other systems store information as a list of file-based changes. Other systems think of the information they keep as a set of files and the changes made to each file over time.
Git doesn’t think of or store its data this way. Instead, Git thinks of these data more like a set of snapshots of miniature file system. Every time you commit, or save the state of your project in Git accordingly, takes a picture of what all your files look like at that moment and stores a reference to that snapshot. It is efficient, if files have not changed, it does not store the file once again, it just a link to the previous same file it has already stored. Git thinks about its data more like a stream of snapshots.
This is an important distinction between Git and nearly all other VCSs. It makes the Git considered almost every aspect of version control that most other systems copied from the previous generation. This make Git more like a mini file system with some incredibly powerful tools built on top of it, or rather than VCSs.
Git Has Integrity
Everything in GIT is check-summed before it stored and it is stored and is then referred to by that checksum. That means it’s impossible to change the contents of any file or directory without Git knowing about it. This function is built into Git at the lowest level & is integral to its philosophy. You can’t lose the information in transit or get file corruption with ought Git being able to detect it.
Git Generally Only Adds Data
When you do actions in Git, nearly all of them only add data to the Git database. It is very hard to get the system to do anything that is not undo able or to make it erase data in any way. In VCS, you can lose or mess up changes you haven’t committed yet, but after you get a snapshot into Git, it is very difficult to loose, especially if you regularly push your database to another repository.
Git Advantages
•Git allows users to selectively pull branches from other repositories accordingly. This provides an upfront mechanism for narrowing the amount of history stored locally.
•Git supports an unlimited number of parent revision during a merge
•Git has rebase command and which allows you to take a local branch and change its branch point to more recent revision.
Git Command References
Users interact with GIT through git command lines. There are GUI like Tortoise Git that runs on top of the GIT command sets.
You can run something like Git log 1a410e to look through your whole history, but you still also have to remember that 10410e is the last commit in order to walk that history to find all those objects. You require a file in which you can store the SHA-1 value under a simple name so you can use the pointer rather than the raw SHA-1 value.
In Git, these are called “references”, you can find the files that contain the SHA-1 values in the, git/refs directory. In the currently project, this directory contains no files, but it contains a simple structure.
