How to push changes to branch?

3 Steps to Commit your changes

Suppose you have created a new branch on GitHub with the name feature-branch.

FETCH

    git pull --all         Pull all remote branches
    git branch -a          List all branches now

Checkout and switch to the feature-branch directory. You can simply copy the branch name from the output of branch -a command above

git checkout -b feature-branch

VALIDATE

Next use the git branch command to see the current branch. It will show feature-branch with * In front of it

git branch   check current branch
git status   check the state of your codebase       

COMMIT

git add .   add all untracked files
git commit -m "Rafactore code or use your message"

Take update and the push changes on the origin server

 git pull origin feature-branch
 git push origin feature-branch

OR you can rebase with the master before commit

git fetch
git rebase origin/master
git push origin feature-branch

First i would like to suggest you to read this nice documentation.

Prerequirements:
- Installed git.
- Have access to the repository.

1. You can download repository following these commands:
   git clone <depositry https or ssh link>

2. First you need to add changes, create commit, add remote branch and then push.
   git remote add <repo name> <repo url>
   Example if you use BitBucket: git remote add origin ssh://[email protected]//.git
   git status // to see all changes (they should be printed with red color)
   git add <file name> // add the file as git staged
git commit or git commit -m 'some message'
git push <remote name> <branch name>

How to download repository

# download a repository
git clone <url>
