Git and GitHub

One of the biggest reasons why I love to be a tech person is "Problem Solving". Where you face some problems there is always someone to help you in your journey.

Programming is not a profession, it's a passion to solve problems. Early days of programming when programmers face a problem working together or in a team a solution pop-up as a Git & GitHub. It resolves every issue regarding programming/coding in more than one developer.

What is Git?

A software maintained by Linux, used for a version control system to manage source code history. Git is installed locally on your system and doesn't use any management feature. It is an open-source license.

What is GitHub?

GitHub is a website maintained by Microsoft, used for hosting services for git repositories.GitHub has a built-in user-management feature. It includes a free tier and a pay-for-user tier. It has an active marketplace for tool integration.

Now we talk about How to use different Commands of Git with GitHub and how we can easily resolve our GitHub-related problems.

#Problem01: How to remove the commit which we did mistakenly?

Solution:

First check logs of the all commits:

then remove the last commit with:

git reset --Head Commit_ID

then push the remaining commits to the origin:

git push origin +branch_name(your master/main branch)
