Git Basics

This practice will help you get comfortable with basic git operations: making changes and publishing them.

We will learn the following git operations:

• add changes to the staging area
• commit changes
• push local commits to publish them to GitHub
• pull changes from the remote repository
• 'branch' create a new branch named "branch-1" and push to Github

Other useful commands to see what is going on the git repository:

• status
• log

• Fork this repo
• Clone this repo
• Update the README: add some lines to the end and push them to GitHub
• Create a new file called newfile.txt, add some contents to it and push it to GitHub
• Update newfile.txt and push the changes to GitHub
• Open the repository on GitHub and make changes to newfile.txt
• Pull the changes to your local repository
• Create a new branch named "branch-1" and push to Github

1. Your repo url in Github

   https://github.com/Cendeal/git-basic.git

2. Your answer for What is the difference between add, commit, and push?

   • definition is different

     add use to add file contents to the index, in fact. if you execute this command it will change your local .git/index file and create a new directory in .git/object to record what have changed.

     commit use to record changes to the repository. if you execute this command it will change your local .git/index too,it will create a file(if not exist) name "COMMIT_EDITMSG" to record your commit message, it will create directory and file in .git/object,and it will change ref of head file.

     push use to update remote refs along with associated objects as local, if you execute this command it will update files about remote record in local like .git/log/ref/remotes/origin/master, .git/refs/remotes/origin/master(this file just records hash string for current master)

   • using order is different.

     For example, if you have changed something in your local, you need to add first,

     and then commit your changes, finally push your commit.

   • scope is different.

     add and commit just in local. If you do not push, it will not change anything into remote
