Task Run CMD Learn What? git cmd
Task 1 python task_1.py git add add
Task 2 python task_2.py git status status
Task 3 python task_3.py git restore restore
Important

First Run task_1.py

Python task_1. Py

It will tell you to add some file , so you can type 'n' to exit program or press "CTRL and c" at the same time and interrept it.
The run the task_1. Py again , and answer the question.

Then Run task_2.py

Python task_2. Py

Then Run task_3.py

Python task_2. Py

After finishing the Task 3, run the quiz. Py

git add

Git add is used to add that file to staging area. I assume no bulb is lit. So

  1. What is staging ?
    Imagine some coder (me) coding a simple quiz like this. How did that get there? He must have uploaded it. But since we are working with git , how do we do that with the git?. Good question , we use git add to add the files.

Add to where?
Remember the original Question "What is Staging ?" , when you add something using git add git goes to staging area. This is a advance topic and you can skip this from here

You can see some new terms in the above picture like

In simple terms a file has 4 states

  1. Modified: means the contents of the file have been changed
  2. Unmodified: you know what it is.
  3. Untracked: Which means git has nothing to do with this file
  4. Staged: git do have bussiness with this file
Important

git status is used to check the status of a file

We will now consider these 2 stages Untracked and Staged

You can see in the Untracked file we now have add_me and it says right there (use "git add <file>....) so what if we do ?
So i run

git add add_me

![alt text](/img/user/11 Classes/Git by Doing/attachments/imgs/image-4.png)
Now there is a new section and it says

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)
        new file:   add_me

is says .... to unstage so the file add_me is staged.

In summary , staging means preparing a file for upload. (we will use the term upload now , but it is called something else (push).)

When do you use the git add

  1. To add new files to staging area
  2. When you modify an exisiting file and upload the modified file.
Tip

You can add multiple files or just add all files using -A option

Git add -A

git restore

As i've said earlier , when you use git add the file get stages , so when i file staged the git start do things to that file , and one of them is to keep a copy of that file and if you accidently delete a staged file , you can recover it using the following command

git restore <file name>
