The git status command returns the current state of the −Working areaStaging areaThis command returns tracked and untracked files and changes made to the repository.

This question can be rephrased as "How to save work in progress (WIP) in Git and return to it later when convenient?"The problem − When we switch branches, Git resets our working directory to contain the snapshot stored in the last commit of the target branch. For example, if we switch from feature to the master branch, Git will replace contents in the working directory with the last commit of the master branch. But if we have local changes in our working directory that we haven't committed yet, these changes will be lost. In this situation, Git will not allow ... Read More

Collaborators will use multiple branches in order to have clearly separated codebase. At some point in time, we may have to merge these branches in order to have the resulting work in the main branch. It is important that we compare the differences in the branches before merging to avoid any conflicts. We will see a couple of different ways to compare two branches −Listing commit differences − This method shows commits that are present in a branch but unavailable in the other branch.Listing file changes − This method compares branches and displays how exactly a certain file is different ...

Branching allows us to diverge from the main line of work and work on something else in isolation. Conceptually, we can think of a branch as a separate isolated workspace. We have a main workspace called the master.We can create a feature branch and work separately on the feature branch to add more features to the project without affecting the main line of work. If there is some error in the feature branch, we can fix it without affecting other collaborator’s work. Once everything is working properly in the feature branch, we can merge it with the main line of ... Read More

The git commit is a 40-digit hexadecimal SHA1 hash. Quite often we need to bookmark a as the commit hash is difficult to memorize. This is where one can use tags. Tags can be used to name a commit. In other words, tags are labels that can be used to identify a specific commit. For e.g., “v1.0, RC1.0” are some ways to name a commit.Tags can be classified as −Lightweight TagsAnnotated TagsLightweight TagsA Lightweight tag is also known as a simple tag. These tags use a name to refer to a specific commit. Lightweight tags are private to a repository. ... Read More

Explanation − In git HEAD is a reference pointer and points to the current commit in the current branch. The below diagram shows that there are two commits ‘Commit#1’ and ‘Commit#2’, where ‘Commit#2’ is the latest commit. Every commit in Git will have a reference to its previous commit. Here, ‘Commit#2’ will have a reference to ‘Commit#1’. The current branch is master. The master pointer points to the latest commit i.e., ‘Commit#2’. The HEAD points to the master. In other words, the HEAD points to the last commit via the master.To check where the HEAD is pointing to, we can ... Read More

A branch in Git is a series of interrelated commits. When a repository is initialized in Git, a branch will be created by default. This default branch is called the master.Multiple branches can be created within a Git repository. When a developer starts working on a new feature of the project, he may create a new feature branch and work in isolation from the master branch. Once the feature is completed changes in that branch will be merged to the master branch. In other words, the master branch will be the main line of work. The master itself is a ... Read More

Let’s say you want to view all commits to the Git repository. The git log command returns all of the commits that have been made to the repository. This command lists the latest commits in chronological order, with the latest commit first.The syntax of the git log command is given below −$ git logThe following screenshot shows how to use the command to view all commits in the current repository.dell@DESKTOP-N961NR5 MINGW64 /e/tut_repo (master) $ git log commit cbc01c8399faf9063eca4ba7781d08eebbe56aaa (HEAD −> master) Author : "Kiran Date: Fri Jan 22 19:38:42 2021 +0530    file2. txt commit 8100770d7274e6bae4e252d7b3c461020b8bc5b2 Author : ...

A version control system is a software that allows you to manage changes to assets (codebase, files) over a period of time. Centralised and Distributed are the two main types of version control systems. The fundamental difference between these two lies in how they −Manage the repositoriesManage the content workflowCentralised ModelCentralised version control systems follow a server-client model. The server holds a single central copy of the project along with a history of changes made to the code base over a period of time. The basic workflow to work with a centralized version control system is given below −When a ... Read More

Following are the best practices for committing in Git −Make small, single−purpose commitsCommitting small sections of code helps the team to understand what work has been completed. It is easier to revert smaller commits and helps you maintain a stable codebase. A commit should act like a wrapper around a set of changes. This means that if you are fixing 2 distinct bugs, use 2 different commits. In other words, changes or code that are logically related should be part of a single commit.Commit messages should be short and detailedCommit messages should begin with a short summary of the change. ...
