What does git mean?

Git is a free, open source distributed version control system, mainly used to manage historical versions of code warehouses. It was developed by Linus Torvalds, the father of Linux, in 2005 to manage Linux kernel code.

The main feature of Git is distributed management. Each developer can download the complete code repository and make modifications. When submitting code changes, Git will record the changes in the local repository and match them with Changes in the remote repository are merged or conflicts resolved. Git is also fast, efficient, and flexible, and can easily handle various code management tasks.

Git operations mainly include the following steps:

1. Create a local warehouse: Use the "git init" command to create a local warehouse directory.
2. Add files: Use the "git add" command to add files to the staging area, or use the "git commit -a" command to submit all changed files to the current version warehouse.
3. Commit changes: Use the "git commit" command to submit all changed files and add corresponding comments.
4. Create a branch: Use the "git branch" command to create a new branch for development and debugging starting from the current branch.
5. Merge branches: Use the "git merge" command to merge two branches and share code changes.
6. Undo changes: Use the "git reset" command to undo a commit in the local branch, or use the "git revert" command to create a new commit and undo a commit.

The use of Git has been widely used in the fields of software development and project management. It effectively solves problems such as file conflicts, branch management, and version control in code management, making teamwork more efficient. Code quality is also improved. For developers, understanding the use of Git can make them more confident in contributing their own code to the team, and can also speed up learning and getting started with new projects.
