Learn Git commands every developer should know

Git and Its Workflow

Git is an open sourced, highly flexible version control system, which allows developers to use code, track the changes in their codes and collaborate efficiently. In contrast to central systems the history of the project can be copied to every team member on his local computer (Git). All project code and the history of updates are stored in this local repository.The simplest Git workflow uses initializing a repository, cloning an existing one, pulling out branches, staging changes, checking them into the local repository and pushing them to a remote repository. In Git branches play an important role because many developers can work on features simultaneously without being able to affect the main code. This isolation aids in the creation of new features or bug fixes being very well tested prior to being merged into the main code.

Basic Git usage instructions to a developer

1 The git config command.

Prior to using Git, you need to set yourself up, with your identity, your username and your email, which will be linked to your commits. The strength of this setting is that it helps in the attribution of your work especially in cases where you are working as a team.

2. git init

git init will create a new Git repository in your local user, creating a hidden directory .git, which will hold all the required metadata needed to control versions. This command is usually the point of origin when I am doing a new project. Git then initiates the tracking of files that have undergone change in filesystem enabling commits that can be extended with branching and restore error.

3. Clone git

The git clone command makes a replica of a distant garage on the local location to pursue a current project or along with an open-source project.This command pulls the whole project, its files, folders and commit history. It also establishes a linkage between your local copy and the remote repository that allows one to push changes as well as to pull updates.

4. git status

The command git status will give you an overview of what is going on in your working directory. It indicates the status of files; that is, what has been changed, new, deleted, or untracked. This command is quite useful in getting to know what changes are waiting to be staged or committed.

5. git add

The git add command puts the changes in your working implementation ready to be committed. A commit does not include changes until one adds the changes to the staging area. It is possible to stage files, or directories.

6. git commit

The git commit command records a new commit that contains your changes that are in your staging and a descriptive message. This is a basic command used to trace changes in your codebase as time goes by and also to create what is termed as checkpoints in the development process. Commit messages make others know the sense of the changes.

• Making a commit: git commit -m "Your commit message"The commits are stored on the computer until it is pushed to a distant repository.
•  

7. push

The git push command can be used to send your local commits somewhere you would like people to see them (an online service, a server, some other computer, etc), so that everyone can see your changes.

• Push to a remote branch: git push <remote> <branch>In case you have created a new branch, you may also have to add the upstream.
•  
• On a new branch: git push --set-upstream <remote> <branch_name>

8. git pull

The git pull command is used to acquire changes in a remote repository and this is then automatically merged into your local branch. This will be necessary to maintain your local repository in sync with the latest updates by your team.

9. branch in git

git branch command is applicable in creating/deleting branches in your repository and listing them. The existence of branches is critical to parallel development and experimentation with new features without threats to stability.

• Reset-editing an existing branch: git checkout <branch-name>
•  
• git branch or, to display all branch names, git branch --list
•  
• Mention of branch: git branch -d <branch-name>

10. git checkout

Git checkout command can find a way of switching branches or commits in your repository. Make sure you commit or stash changes in your current branch, before completing a switch.

• Changing the branch to an available one: git checkout <branch-name>
•  
• New branch and switch to a new branch: git checkout -b <new-branch-name>

11. git Merge

Git merge command is used to incorporate changes in one branch over the other. This is important to merge branch developments of two or more developers or integrating feature branches into the main one. One has to be on the target branch into which they want to merge to run the command.

• Combining a branch: git merge <source_branch>In the event of conflicts, Git will have to ask you to resolve it by hand.
•  

Git Commands that streamline the work that you do.

12. git log

The git log command allows an in-depth view of the history of all the commits done in your repository with their respective commit hash, author, date and message. This is priceless in terms of project history review, change understanding and debugging.

13. diff.

git diff is used to view the differences between different states of your repository (e.g. between your working directory and the most recent commit, or between two commits, or between two branches). It brings to the fore what is added, removed or changed.

• Comparing the ongoing changes with one another: git diff
•  
• Branch then general comparison: git diff branch1..branch2

14.STASH

The git stash command stores anything on the working directory not yet committed, but you want to keep that stuff to some later point. It comes in handy when you have to change branches, or work on another task without committing partial commits.

15. reset git

Git reset command can either undo modifications on your working directory or reset your commit history by repositioning the HEAD pointer to a given state. A variety of options can be applied to this command depending on the extent to which you wish to reverse.

• Soft reset: git reset --soft HEAD~1 (moves the HEAD ahead, keeps the changes in staging, lives to see another day)
•  
• Mixed reset: git reset HEAD~1 (moves HEAD,  changes, leaves them in working directory, so they are no longer in the commit)
•  
• Hard reset: git reset HEAD~1--hard (moves HEAD, removes changes in staging and working directory)Git reset HEAD~1--hard has the potential to delete work that is not committed and is considered drastic.

16. Git revert

The git revert command works by reversing one commit by creating a new commit with reversed changes, leaving project history intact. It is safe compared to resetting your Git history, which is riskier to do when managing a shared set of repositories.

• Undoing a commit: revert| pending-quotes| germContin© Royale

17. cherry-pick using git

Git cherry- pick executes certain commits of one branch to another, which is not an assembly of the entire branch. This comes in handy when you have to add some modifications (e.g. bug fix) of some other branch.

• Cherry picking a commit: git cherry-pick <commit-hash>

Git took place Resource Learning

Character building sites, such as Uncodemy, provide worthwhile courses in Git and general development to those wanting to build on their effectiveness with git and other development programs. Although the given sources specify that Uncodemy is a worldwide IT educational institution that teaches more than 200 courses, such as Data Science, Business Analysis, Blockchain and Artificial Intelligence, the sources do not narrow down to teach the course of Git or version control in Uncodemy. The Data Science course offered by Uncodemy is dedicated to both the curriculum that corresponds to the industry and practice with applied projects and professional guidance. They focus more on the application part by ensuring that the study is project based with an expected outcome of achieving one hundred percent in job placements.

Still, the results of the search do not directly indicate the details connected to Uncodemy courses directly speaking about Git commands or version control. In order to get to know more about Git commands and best practices, it is advisable to refer to elaborate guides and tutorials of reliable sources.
