push code into specific branch


To push code into a specific branch in Git, you can follow these steps:

First, make sure you are in the correct branch by running the command:

git branch


This will show you the list of branches in your local repository, and the branch that you are currently on will be marked with an asterisk (*).

If you are not in the correct branch, switch to the desired branch using the command:
php

git checkout -b <branch-name>
Replace <branch-name> with the name of the branch you want to switch to.

Once you are in the correct branch, add the changes you want to commit using the command:
csharp
Copy code
git add .
This will add all the changes in your current directory to the staging area.

Commit the changes using the command:
sql

git commit -m "commit message"
Replace "commit message" with a brief description of the changes you made.

Finally, push the changes to the remote repository using the command:
perl

git push origin <branch-name>
Replace <branch-name> with the name of the branch you want to push the changes to.

That's it! Your code changes should now be pushed to the specified branch in the remote repository

git pull origin master

git add . 
git commit -m "Added new functionality"
git push origin main

This message indicates that your current branch is 10 commits behind the main branch. This means that the main branch has progressed further than your current branch and has 10 more commits that your branch does not have.

To update your branch with the changes from the main branch, you can use the git pull command. This will fetch the changes from the remote repository and merge them into your current branch.

Here are the steps you can follow:

Make sure you are on your current branch by running git branch. The current branch will be highlighted with an asterisk.
Run git pull origin main. This will fetch the changes from the main branch in the remote repository and merge them into your current branch.
Resolve any merge conflicts that may arise during the merge process. You will need to edit the conflicting files manually to resolve the conflicts.
Once you have resolved the conflicts, add the changes using git add . or git add <file> for each file you have resolved.
Commit the changes using git commit -m "Merge changes from main branch"
Push the changes to the remote repository using git push origin <your-branch-name>.
After these steps, your branch should be updated with the changes from the main branch.

ls(Get list from current folder)
cd(To change directory)
cd .. (Back to folder)
mkdir( Make any folder)
rm (For remove)
pwd ( Print Directory Path )
mv ( To rename any folder)
touch indec.html style.css script.js (Makes files)

What is Git

{To start local repositry to write (git init)}

Git is simply version control of code we can get previous version of code.

(git log) to check all commits which have done in local repository(.git) which 
has snaps of your versions of code 
 

git checkout "241252154125125125125" (if we want to go previous version of code)
 
git checkout master ( To go to current version of code)

git branch branchname (It wil create branch) 

git log --oneline --all --graph  

/* Hide scrollbar indicator */
::-webkit-scrollbar {
  width: 0;
  height: 0;
  background-color: transparent;
}

/* Optional: add a border around the scrollable content to indicate where scrolling is possible */
.scrollable-content {
  border: 1px solid #ccc;
}
Note that this method only works for WebKit browsers and does not affect other browsers. Therefore, it's recommended to use the overflow-y-auto class (or another appropriate Tailwind CSS utility class) to ensure consistent styling and behavior across all browsers.

Here's an example of how to use the overflow-y-auto class on an element:

html
Copy code
<div class="overflow-y-auto">
  <!-- content here -->
</div>
The overflow-y-auto class allows scrolling in the y-axis when the content overflows the container, and displays the scrollbar indicator only when necessary.

npx create-react-app .

I have to write dot so that i install dependencies in cureent folder and then you can follow 
Docs.

Install this dependencies as well 

npm i react-router-dom@6.4.2 react-icons

And then make components folder, pages folder, Assests Folder.

And then Write code for routers in App.js

Step 1 (This is the step one)
npm init
Step 2 (This is the step 2 install general dependencies)
npm i nodemon mongoose dotenv bcrypt jsonwebtoken cookie-parser express
Step 3 
Make following folders 
1) controllers
2) models
3) routes
4) utils
5) .env
6) server.js and then make change in package json file => "scripts": {
    "start": "nodemon index.js"
  },
