If you are not sharing your repo with others, this is useful to push all your branches to the remote, and --set-upstream tracking correctly for you:

git push --all -u

(Not exactly what the OP was asking for, but this one-liner is pretty popular)

If you are sharing your repo with others this isn't really good form as you will clog up the repo with all your dodgy experimental branches.

Prior to the introduction of git push -u, there was no git push option to obtain what you desire. You had to add new configuration statements.

If you create a new branch using:

$ git checkout -b branchB
$ git push origin branchB:branchB

You can use the git config command to avoid editing directly the .git/config file:

$ git config branch.branchB.remote origin
$ git config branch.branchB.merge refs/heads/branchB

Or you can edit manually the .git/config file to add tracking information to this branch:

[branch "branchB"]
    remote = origin
    merge = refs/heads/branchB

Simply put, to create a new local branch, do:

git branch <branch-name>

To push it to the remote repository, do:

git push -u origin <branch-name>

A slight variation of the solutions already given here:

1. Create a local branch based on some other (remote or local) branch:

   git checkout -b branchname
   

2. Push the local branch to the remote repository (publish), but make it trackable so git pull and git push will work immediately

   git push -u origin HEAD
   

   Using HEAD is a "handy way to push the current branch to the same name on the remote". Source: https://git-scm.com/docs/git-push In Git terms, HEAD (in uppercase) is a reference to the top of the current branch (tree).

   The -u option is just short for --set-upstream. This will add an upstream tracking reference for the current branch. you can verify this by looking in your .git/config file:

   

I simply do

git push -u origin localBranch:remoteBranchToBeCreated

over an already cloned project.

Git creates a new branch named remoteBranchToBeCreated under my commits I did in localBranch.

Edit: this changes your current local branch's (possibly named localBranch) upstream to origin/remoteBranchToBeCreated. To fix that, simply type:

git branch --set-upstream-to=origin/localBranch

or

git branch -u origin/localBranch

So your current local branch now tracks origin/localBranch back.

git push --set-upstream origin <your branch name>

OR

git push -u origin <your branch name>

edit Outdated, just use git push -u origin $BRANCHNAME

Use git publish-branch from William's miscellaneous Git tools.

OK, no Ruby, so - ignoring the safeguards! - take the last three lines of the script and create a bash script, git-publish-branch:

#!/bin/bash
REMOTE=$1 # Rewrite this to make it optional...
BRANCH=$2
# Uncomment the following line to create BRANCH locally first
#git checkout -b ${BRANCH}
git push ${ORIGIN} ${BRANCH}:refs/heads/${BRANCH} &&
git config branch.${BRANCH}.remote ${REMOTE} &&
git config branch.${BRANCH}.merge refs/heads/${BRANCH}

Then run git-publish-branch REMOTENAME BRANCHNAME, where REMOTENAME is usually origin (you may modify the script to take origin as default, etc...)

Complete Git work flow for pushing local changes to anew feature branch looks like this

Pull all remote branches

git pull --all

List all branches now

git branch -a  

Checkout or create branch(replace <feature branch> with your branch name):

git checkout -b <feature branch>

shows current branch. Must show with * In front of it

git branch      

Add your local changes (. is on purpose here)

git add .

Now commit your changes:

git commit -m "Refactored/ Added Feature XYZ"

Important: Take update from master:

git pull origin feature-branch

Now push your local changes:

git push origin feature-branch

I suppose that you have already cloned a project like:

git clone http://github.com/myproject.git

1. Then in your local copy, create a new branch and check it out:

   git checkout -b <newbranch>
   

2. Supposing that you made a "git bare --init" on your server and created the myapp.git, you should:

   git remote add origin ssh://example.com/var/git/myapp.git
   git push origin master
   

3. After that, users should be able to

   git clone http://example.com/var/git/myapp.git
   

NOTE: I'm assuming that you have your server up and running. If it isn't, it won't work. A good how-to is here.

ADDED

Add a remote branch:

git push origin master:new_feature_name

Check if everything is good (fetch origin and list remote branches):

git fetch origin
git branch -r

Create a local branch and track the remote branch:

git checkout -tb new_feature_name origin/new_feature_name

Update everything:

git pull

To create a new branch by branching off from an existing branch

git checkout -b <new_branch>

and then push this new branch to repository using

git push -u origin <new_branch>

This creates and pushes all local commits to a newly created remote branch origin/<new_branch>

For GitLab version prior to 1.7, use:

git checkout -b name_branch

(name_branch, ex: master)

To push it to the remote repository, do:

git push -u origin name_new_branch

(name_new_branch, example: feature)

I made an alias so that whenever I create a new branch, it will push and track the remote branch accordingly. I put following chunk into the .bash_profile file:

# Create a new branch, push to origin and track that remote branch
publishBranch() {
  git checkout -b $1
  git push -u origin $1
}
alias gcb=publishBranch

Usage: just type gcb thuy/do-sth-kool with thuy/do-sth-kool is my new branch name.

You can do it in 2 steeps:

1. Use the checkout for create the local branch:

git checkout -b yourBranchName

Work with your Branch as you want.

2. Use the push command to autocreate the branch and send the code to the remote repository:

git push -u origin yourBanchName

There are mutiple ways to do this but I think that this way is really simple.

It is now possible (git version 2.37.0) to set git config --global push.autoSetupRemote true. Also see: Automatically track remote branch with git

I think this is the simplest alias, add to your ~/.gitconfig

[alias]
  publish-branch = !git push -u origin $(git rev-parse --abbrev-ref HEAD)

You just run

git publish-branch

and... it publishes the branch

Building slightly upon the answers here, I've wrapped this process up as a simple Bash script, which could of course be used as a Git alias as well.

The important addition to me is that this prompts me to run unit tests before committing and passes in the current branch name by default.

$ git_push_new_branch.sh

  Have you run your unit tests yet? If so, pass OK or a branch name, and try again

  usage: git_push_new_branch {OK|BRANCH_NAME}

  e.g.

  git_push_new_branch           -> Displays prompt reminding you to run unit tests
  git_push_new_branch OK        -> Pushes the current branch as a new branch to the origin
  git_push_new_branch MYBRANCH  -> Pushes branch MYBRANCH as a new branch to the origin

git_push_new_branch.sh

function show_help()
{
  IT=$(cat <<EOF

  Have you run your unit tests yet? If so, pass OK or a branch name, and try again

  usage: git_push_new_branch {OK|BRANCH_NAME}

  e.g.

  git_push_new_branch.sh           -> Displays prompt reminding you to run unit tests
  git_push_new_branch.sh OK        -> Pushes the current branch as a new branch to the origin
  git_push_new_branch.sh MYBRANCH  -> Pushes branch MYBRANCH as a new branch to the origin

  )
  echo "$IT"
  exit
}

if [ -z "$1" ]
then
  show_help
fi

CURR_BRANCH=$(git rev-parse --abbrev-ref HEAD)
if [ "$1" == "OK" ]
then
  BRANCH=$CURR_BRANCH
else
  BRANCH=${1:-$CURR_BRANCH}
fi

git push -u origin $BRANCH

git push -u origin HEAD

In case you want the remote and local branch to have the same name and don't want to enter the branch name manually

If you want to push local repository to origin copy and paste code below in the terminal but don't forget to change name of branch:

git checkout -b <name of branch>

git push -u origin <name of branch>

For greatest flexibility, you could use a custom Git command. For example, create the following Python script somewhere in your $PATH under the name git-publish and make it executable:

#!/usr/bin/env python3

import argparse
import subprocess
import sys


def publish(args):
    return subprocess.run(['git', 'push', '--set-upstream', args.remote, args.branch]).returncode


def parse_args():
    parser = argparse.ArgumentParser(description='Push and set upstream for a branch')
    parser.add_argument('-r', '--remote', default='origin',
                        help="The remote name (default is 'origin')")
    parser.add_argument('-b', '--branch', help='The branch name (default is whatever HEAD is pointing to)',
                        default='HEAD')
    return parser.parse_args()


def main():
    args = parse_args()
    return publish(args)


if __name__ == '__main__':
    sys.exit(main())

Then git publish -h will show you usage information:

usage: git-publish [-h] [-r REMOTE] [-b BRANCH]

Push and set upstream for a branch

optional arguments:
  -h, --help            show this help message and exit
  -r REMOTE, --remote REMOTE
                        The remote name (default is 'origin')
  -b BRANCH, --branch BRANCH
                        The branch name (default is whatever HEAD is pointing to)

Alternatively, use switch

git switch -c <new_branch>

git push -u origin <new_branch>
