Git has emerged as a tool no developer can do without. It is one of the most powerful and flexible version control systems when it comes to developing software. Knowledge of key Git commands is essential to developing any software efficiently and seamlessly, whether in personal environments or large team environments. In this article, you will learn all the must-know Git commands every developer should be aware of so as to move confidently within the boundaries of their development workflow.
Version control is indispensable in software development because the same project can be operated by multiple developers, one's changes can be monitored, and earlier versions retrieved in case of need. Due to its speed and flexibility, Git has gradually become the standard for most developers. Through essential Git commands, their productivity improves, and consequently, better project management as well as collaboration can occur.
Essential Git Commands
This is the breakdown of some basic Git commands that every developer should know.
1. `git init` starts a new Git repository in the current directory. This creates the versioning control structure and all the necessary things for Git, including an invisible `.git` directory with the internal metadata used by Git. It begins with using version control on a project or directory already created but not tracked by Git beforehand.
2. `git clone` lets you make a copy on your local machine of the repository hosted at someplace with a Git repository. Most people will use this for their first command when checking in to a project get the repository downloaded including all of its history that way, and make the repository available on your development machine.
3. `git add` stages changes for the next commit. Whether you change an existing file or write a new one, all of that needs to go through this command before getting committed.
4. `git commit` saves your changes to the local repository. Once files have been added to the staging area, this command makes a snapshot of the project's current state. This command requires a message explaining what changes have been made.
5.`git push` pushes the changes on your local repository to another remote repository such as Github or Gitlab. Often done after a commit if you want other people also working on that project with you to get your commits.
6. `git pull`: Fetches changes from other repositories and imports them into yours. It does this by combining `git fetch` and `git merge` on your behalf to update a local project from the one on the remote source in question.
7. `git branch` To create, list or delete the branches. You can, then, develop new features without breaking the main code in terms of bugs or some critical issues.
8. `git merge` To merge from another branch. This happens normally when the feature branch is to be used once the development is successful.
9. `git status` gives you a snapshot view of your working directory. That is, it tells which files have changes staged to be committed, which one has changes not staged and which ones are not even tracked by Git.
10. `git log` will, therefore, give you all the commit history in this repository, showing you what all the previous commits happened, with their messages, their authors, and the exact time when they were executed.
The knowledge and mastery of the basic commands in Git can have very significant impacts on your workflow in the development process. From `git init` where you begin and initiate a repository to `git pull` and `git push`, which permits you to collaborate with others such commands form the foundations or building blocks of good version control. Whether it is working on a single project or working through more significant teams, all your code changes will be taken care of and tracked with it.
