Basic Operation in Git

• Initialize
• Add
• Commit
• Push
• Pull

Initialize : It is used to create an empty directory or re-initialize existing directory one from the repository. For the initialize we use "git init" command, this command will create .git directory with sub-directory and there templates file. after the successfully initialize we will create or add our files/code.

git init

We can see the index with the help of "git status" command, it will lists all the modified files which are ready to be added to the local repository.

git status

Add : It is used to update index by current content found in the working tree/directory. now we are ready to commit

git add

Commit : It is used to commit the code

git commit

git commit -m "messages of code"

Push : It will used to publish all the commits/changes from the local repository to remote repository

git push

Pull : It will use to fetches changes from a remote repository to a local repository

git remote add origin  <Git Repo URL>

git pull origin master
