Are you working on your next big software idea? Then, you must know the elaborate technical concepts and requirements of a large distributed team for the project. The only two words that can help you address these concerns are version control. Version control, also known as subversion control or revision control, is ideal for controlling large projects.
The popularity of version control tools such as Git has been largely evident in the access to their functionalities with simple Git commands. Git is a renowned version control system that allows programmers, project managers, and writers to manage a specific project from different angles. The best part about Git is that nobody has to worry about the actions of other members of the project.

Changes made to the source code could always be reverted back to older desired versions with the help of Git. So, if you have decided to learn about Git, then you would need a handy Git commands tutorial to start. The following discussion dives into a detailed illustration of commands in Git with practical examples.
What is Git, and Why is It Important?
Before moving towards an outline of the common Git commands, let us reflect briefly on Git and its importance first. The definitions of Git present it as a distributed revision control and source code management system with a focus on speed. It was initially developed for Linux kernel development and is presently distributed for free under the GNU General Public License Version 2.
The basic functionality of Git is to enable software developers to work in collaboration and maintaining a thorough history of their work. As a distributed version control system, Git overcomes the issues with centralized version control such as loss of project history in event of data corruption or lack of proper backup. You can notice in any Git tutorial that Git clients check the latest snapshot of a directory alongside mirroring the repository completely.
In the event of server failure, a repository from any client could be copied back to the server for restoration. As a result, Git does not rely on a central server for its operations, and users could perform various operations while offline. Users can create branches, commit changes, view logs, and conduct other operations when they are offline with Git. Network connection would be required only for publishing changes and adopting the latest changes.
Reasons to Learn Git Commands
So, you can find out that Git is a highly functional version control system from any Git tutorial. However, it is still reasonable to wonder about the possible reasons to go through the trouble of learning Git commands. Git provides a wide range of functionalities for developers, designers, product management, and marketing. In addition, it is also a vital tool that supports use cases of customer support, human resources, and a limited budget. The following benefits of Git can further strengthen your resolve to learn the commands in Git effectively.
- Git is a free and open-source, thereby enabling flexibility and cost-efficiency.
- The majority of operations on Git are performed locally, and there is no need for a central server. Therefore, you get the benefits of speed within a compact infrastructure with the help of Git.
- One of the foremost reasons to get started with Git commands is the benefit of security with Git. The common cryptographic hash function (SHA1) can help in the naming and identification of objects within Git. As a result, there is no possibility of changes in file, date, commit message, or any other data.
- Git takes away the burden of hardware on the server-side as the majority of the heavy work happens on the client hardware.

The .git folder remains hidden, and you have to disable the feature in the case of Windows to see it. In the case of Linux, you can use the ‘ls –a’ command for viewing the .git directory. It is recommended that no one should tamper the contents of the .git folder. The example of the command can be presented in the following way.
git init Initialized empty Git repository in /home/username/GIT/.git/
2. git config
git config is one of the basic Git commands that you must learn. The command helps in setting the configuration values for email, username, file formats, preferred file algorithm, and many other attributes. The example of the command is as follows,
git config –global user.name “Username” git config –global user.email “[email protected]”
3. git add
The ‘git add’ command helps in adding file modifications, presently in the working directory to the user’s index. The command helps in adding untracked files that are ready for committing to the remote repository. The example of using the ‘git add’ command is as follows.
git add file_1
This command would add file_1 to the staging area.
4. git clone
The ‘git clone’ command helps in the creation of a copy of the Git repository from a remote source. The command can also add the original location as the remote location. As a result, users can fetch from the original location again and push to it with the right permissions. The example of using the command could be seen as follows.
git clone [email protected]:user/test.git
5. git commit
The ‘git commit’ command is one of the notable Git commands every beginner should learn. The command collects all changes written to the index and then creates a new commit object pointing towards the index. In addition, it also sets the branch for pointing out to the new commit. The example of using the command is as follows,
git commit –m ‘committing added changes’ git commit –a –m ‘committing all changes, equals to git add and git commit’
6. git rm
The ‘git rm’ command is a basic entry in any Git commands cheat sheet. The command can help in removing files from your index and working directory. As a result, the removed files cannot be tracked. The example of using the command is as follows,
git rm filename
7. git merge
The ‘git merge’ command is the ideal mention among Git commands for merging one or more branches in an existing branch. The command also ensures the automatic creation of a new commit in cases where no conflicts are encountered. The example of using the command is as follows,
git merge newbranchversion
8. git status
The ‘git status’ command can help in displaying the status of files in the index and the ones in the working directory. The command would list out untracked, modified, and staged files easily. An example of using the ‘git status’ command is as follows,
git status # On branch master # # Initial commit # # Untracked files: # # (use “git add <file>…” to include in what will be committed) # README
9. git branch
The ‘git branch’ is a notable mention among Git commands for beginners. It can help in listing the existing branches, including remote branches with the facility of ‘-a.’ The command can also help in the creation of a new branch if there is a branch name provided for it. The example of using the command is as follows,
git branch –a * master remotes/origin/master
10. git tag

git tag –a v2.0 –m ‘this is version 2.0 tag’
11. git reset
The ‘git reset’ command is useful for resetting your index and working directory to the state created by last commit. The command can help in taking users back. It also ensures the preservation of any changes introduced in the file. The example of using the command is as follows,
git reset –hard HEAD
12. git remote
The ‘git remote’ is a prominent entry among Git commands that beginners should learn. The command can help in showcasing all the remote versions of the repository. The example of the command is as follows,
