How long did it take to write git?

Git is a distributed version control system created by Linus Torvalds in 2005. From its initial release to the present, Git has become one of the most widely used version control tools in the software development industry. Git is not only favored by developers because of its excellent performance and functionality, but also widely adopted because of the efficiency and convenience it brings.

The birth of Git

Before the emergence of Git, the most widely used version control systems were CVS and Subversion. However, there are a few areas where these two tools fall short. CVS's performance is poor, and Subversion's branching and merging operations are difficult. Against this background, Linus Torvalds began to develop his own version control tool.

Before Git entered the spotlight, Linus had tried BitKeeper. This is a commercial version control tool developed by Larry McVoy. However, since use of the tool by Linux kernel developers was considered copyright infringement, Larry McVoy stopped providing BitKeeper to the Linux kernel community.

In this context, Linus Torvalds began to develop Git. He chose GPLv2 as Git's license and hosted it on SourceForge, an open source project hosting service. Eventually, Git's open source became a popular choice among developers, and it became one of the leading distributed version control systems.

Advantages of Git

Git has many advantages, making it one of the widely used version control tools in the software development industry. Here are some of the advantages:

Distributed

Git is a distributed version control tool. This means that developers can clone their code base locally and then modify and version manage it in their own local repository. This distributed approach allows developers to work without an internet connection and then synchronize changes back to the main code base.

Excellent performance

Git's performance is excellent. It's fast and capable of handling large code bases and extensive history. This makes Git the preferred version control tool for large projects.

Easy to use

Git’s command line interface may be unfamiliar to some developers. However, once you master some basic operations, using Git becomes very simple. At the same time, many integrated development environments also provide Git graphical interfaces, which makes learning Git easier.

Support branching and merging

Unlike other version control tools, Git encourages developers to use branches. Git provides almost unlimited capabilities for branching and merging operations, which makes collaborative development by multiple people easier and more efficient.

Use of Git

There are many convenient operations using Git, which can make it easier for developers to manage their own code libraries. Below are some commonly used Git commands.

clone

Use the clone command to copy the entire code base from the remote repository to the local one.

add

Add files or folders to the Git staging area.

commit

Submit the changes in the staging area to the local Git repository.

push

Push changes from the local Git repository to the remote repository.

pull

Pull changes from the remote warehouse to the local warehouse.

branch

Create a new branch.

merge

Merge a branch into the current branch.

checkout

Switch to the specified branch or commit.

Conclusion

Git is a powerful version control tool that has many advantages, such as excellent performance, ease of use, support for branching and merging, etc. For developers, mastering Git is an important skill. Learning the basics of Git will help you better manage your code and collaborate more efficiently with other developers.
