Importance of Git for a Programmer

What is git

Git is a version control system (VCS) in which we can do tracking changes in project directory and manage source code. It is free and open source. A complete long-term change history of every file. This means every change made by many individuals over the years. Git takes snapshots of a project, and stores those snapshots as unique versions. Git is designed for distributed development. If you’re involved with a project you can clone the project’s Git repository, and then work on it as if it was the only copy in existence. Every developer’s working copy of the code is also a repository that can contain the full history of all changes.

We can install the basic Git tools, First we go to Git installation URL ,There are many interfaces available for Git like GitHub, GitLab, Savannah, BitBucket, and SourceForge etc.

There are many tools available in market right now like Git to revision control and SCM (source code management) but why Git is most popular ? Well the reason is :

  • Git tracks state, history and integrate of the source tree
  • Git keeps old versions for you if some developer did any mistake in code then you’ll always have previous version to fix it
  • Multiple developers can work together, once they write code in their local machine and commit it then other developers can pull it easily.
  • Large developers community and online websites to upload your source codes or get others source codes to make your work easier
  • Lots of software available for both who comfortable with command line and for others GUI tools
  • Easy and clear documentation to get started with Git will not use much bandwidth you don’t have to connect with your server always you just need to connect to push code when you are done

Since Git was designed with a big project like Linux in mind, there are a lot of Git commands. However, to use the basics of Git, you’ll only need to know a few terms. They all begin the same way, with the word “git.”

git init: Initializes a new Git repository. Until you run this command inside a repository or directory, it’s just a regular folder. Only after you input this does it accept further Git commands.

git config: Short for “configure,” this is most useful when you’re setting up Git for the first time.

git help: Forgot a command? Type this into the command line to bring up the 21 most common git commands. You can also be more specific and type “git help init” or another term to figure out how to use and configure a specific git command.

git status: Check the status of your repository. See which files are inside it, which changes still need to be committed, and which branch of the repository you’re currently working on.

git add: This does not add new files to your repository. Instead, it brings new files to Git’s attention. After you add files, they’re included in Git’s “snapshots” of the repository.

git commit: Git’s most important command. After you make any sort of change, you input this in order to take a “snapshot” of the repository. Usually it goes git commit -m “Message here.” The -m indicates that the following section of the command should be read as a message.

git branch: Working with multiple collaborators and want to make changes on your own? This command will let you build a new branch, or timeline of commits, of changes and file additions that are completely your own. Your title goes after the command. If you wanted a new branch called “cats,” you’d type git branch cats.

git checkout: Literally allows you to “check out” a repository that you are not currently inside. This is a navigational command that lets you move to the repository you want to check. You can use this command as git checkout master to look at the master branch, or git checkout cats to look at another branch.

git merge: When you’re done working on a branch, you can merge your changes back to the master branch, which is visible to all collaborators. git merge cats would take all the changes you made to the “cats” branch and add them to the master.

git push: If you’re working on your local computer, and want your commits to be visible online on GitHub as well, you “push” the changes up to GitHub with this command.

git pull: If you’re working on your local computer and want the most up-to-date version of your repository to work with, you “pull” the changes down from GitHub with this command.

GitHub is a code hosting platform for version control and collaboration. It lets you and others work together on projects from anywhere.

This tutorial teaches you GitHub essentials like repositories, branches, commits, and Pull Requests. You’ll create your own Hello World repository and learn GitHub’s Pull Request workflow, a popular way to create and review code.

GitHub can be separated as the Git and the Hub. GitHub service includes access controls as well as collaboration features like task management, repository hosting, and team management.

  • The key benefits of GitHub are as follows.
  • It is easy to contribute to open source projects via GitHub.
  • It helps to create an excellent document.
  • You can attract the recruiter by showing off your work. If you have a profile on GitHub, you will have a higher chance of being recruited.
  • It allows your work to get out there in front of the public.
