About Git Git is a Source Code Management Tool.It is a free and open-source version control system.Git helps to keep track of different versions of a single code base by tracking all changes.Git is Distributed Version Control System(DVCS). Stages in git Workspace/Working directory Staging area Local Repository Workspace:- it is your working directory Staging Area:- Local repo:- Git CommitIt stores changes in repositoryIt uses SHA-1 checksum conceptIf you change anything in code then commit id will be changedYou can easily track changes through commit id Tags in gitTag assigns a meaningful name with a specific version in repository, like we let some change in code and assign tag with commit id to identify its easily. Git PushWhen we done with our code and went to add the code in remote repository, then we will use the push command to transfer the code from local repository to remote repository. Git PullPull command copy the code from remote repository to local repository Branch in GitBranch is a place where your code is placed, it may be master or main branch.Each task has one separate branch. Branch Merge Branch merge means if someone working some other code and you went to add their code in your branch/code then merge command will be use. Git Conflict When same file having different content in different branches, git conflict occurs when you merge them in single branch. Git Stashing Git stashing is a temporary storage for your code, it mean if your are working on new project and someone told you to work on old project, in this case you can store your new project in stashing area for few hours. Git ResetIt is powerful command that is used to reset local changes to the state of git repository. We will use this command when we want to discard the changes, it will revert the commit id to previous commit id. Git RevertThe revert command helps you to create new commit and it will create new commit which is opposite to existing commit without deleting data.
