Why do I need to do `--set-upstream` all the time?

A shortcut, which doesn't depend on remembering the syntax for git branch --set-upstream ¹ is to do:

git push -u origin my_branch

... the first time that you push that branch. Or, to push to the current branch from a branch of the same name (handy for an alias):

git push -u origin HEAD

You only need to use -u once, and that sets up the association between your branch and the one at origin in the same way as git branch --set-upstream does.

Personally, I think it's a good thing to have to set up that association between your branch and one on the remote explicitly. It's just a shame that the rules are different for git push and git pull.

1 It may sound silly, but I very frequently forget to specify the current branch, assuming that's the default - it's not, and the results are most confusing.

Update 2012-10-11: Apparently I'm not the only person who found it easy to get wrong! Thanks to VonC for pointing out that git 1.8.0 introduces the more obvious git branch --set-upstream-to, which can be used as follows, if you're on the branch my_branch:

git branch --set-upstream-to origin/my_branch

... or with the short option:

git branch -u origin/my_branch

This change, and its reasoning, is described in the release notes for git 1.8.0, release candidate 1:

It was tempting to say git branch --set-upstream origin/master, but that tells Git to arrange the local branch origin/master to integrate with the currently checked out branch, which is highly unlikely to be what the user meant. The option is deprecated; use the new --set-upstream-to (with a short-and-sweet -u) option instead.

---

You can make this happen with less typing. First, change the way your push works:

git config --global push.default current

This will infer the origin my_branch part, thus you can do:

git push -u

Which will both create the remote branch with the same name and track it.

---

This is my most common use for The Fuck.

$ git push
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin master

$ fuck
git push --set-upstream origin master [enter/↑/↓/ctrl+c]
Counting objects: 9, done.
...

Also, it's fun to type swear words in your terminal.

---

You can simply

git checkout -b my-branch origin/whatever

in the first place. If you set branch.autosetupmerge or branch.autosetuprebase (my favorite) to always (default is true), my-branch will automatically track origin/whatever.

See git help config.

---

You can set upstream simpler in two ways. First when you create the branch:

git branch -u origin/my-branch

or after you have created a branch, you can use this command.

git push -u origin my-branch

You can also branch, check out and set upstream in a single command:

git checkout -b my-branch -t origin/my-branch

My personally preference is to do this in a two-step command:

git checkout -b my-branch
git push -u origin my-branch

---

You can use:

git config --global branch.autosetupmerge always

which will link the upstream branch each time you create or checkout a new branch.

See https://felipec.wordpress.com/2013/09/01/advanced-git-concepts-the-upstream-tracking-branch/

This also works with branch.autosetuprebase, if you follow a more rebase focused workflow, but don't use this unless you know what you're doing, as it will default your pull behavior to rebase, which can cause odd results.

---

By the way, the shortcut to pushing the current branch to a remote with the same name:

$ git push -u origin HEAD

---

If the below doesn't work:

git config --global push.default current

You should also update your project's local config, as its possible your project has local git configurations:

git config --local push.default current

---

I personally use these following alias in bash

in ~/.gitconfig file

[alias]
    pushup = "!git push --set-upstream origin $(git symbolic-ref --short HEAD)"

and in ~/.bashrc or ~/.zshrc file

alias gpo="git pushup"
alias gpof="gpo -f"
alias gf="git fetch"
alias gp="git pull"

---

git config --global push.autoSetupRemote true

The OP asks:

I learned that I can make it work with: git branch --set-upstream my_branch origin/my_branch But why do I need to do this for every branch I create?

You do not need to set upstream all the time. Not anymore (eleven years later).

With Git 2.37 (Q3 2022), a git config --global push.autoSetupRemote true will take care of that for you.

See commit 05d5775, commit 8a649be, commit bdaf1df (29 Apr 2022) by Tao Klerks (TaoK).

push: new config option "push.autoSetupRemote" supports "simple" push Signed-off-by: Tao Klerks

In some "simple" centralized workflows, users expect remote tracking branch names to match local branch names. "git push"(man) pushes to the remote version/instance of the branch, and "git pull"(man) pulls any changes to the remote branch (changes made by the same user in another place, or by other users). This expectation is supported by the push.default default option "simple" which refuses a default push for a mismatching tracking branch name, and by the new branch.autosetupmerge option, "simple", which only sets up remote tracking for same-name remote branches. When a new branch has been created by the user and has not yet been pushed (and push.default is not set to "current"), the user is prompted with a "The current branch %s has no upstream branch" error, and instructions on how to push and add tracking. This error is helpful in that following the advice once per branch "resolves" the issue for that branch forever, but inconvenient in that for the "simple" centralized workflow, this is always the right thing to do, so it would be better to just do it. Support this workflow with a new config setting, push.autoSetupRemote, which will cause a default push, when there is no remote tracking branch configured, to push to the same-name on the remote and --set-upstream. Also add a hint offering this new option when the "The current branch %s has no upstream branch" error is encountered, and add corresponding tests.

The new hint is:

To have this happen automatically for branches without a tracking upstream, see 'push.autoSetupRemote' in 'git help config'

git config now includes in its man page:

push.autoSetupRemote If set to "true" assume --set-upstream on default push when no upstream tracking exists for the current branch; This option takes effect with push.default options 'simple', 'upstream', and 'current'. It is useful if by default you want new branches to be pushed to the default remote (like the behavior of 'push.default=current') and you also want the upstream tracking to be set. Workflows most likely to benefit from this option are 'simple' central workflows where all branches are expected to have the same name on the remote.

---

For what it is worth, if you are trying to track a branch that already exists on the remote (eg. origin/somebranch) but haven't checked it out locally yet, you can do:

$ git checkout --track origin/somebranch

Note: '-t' is the shortened version of '--track' option.

This sets up the same association right off the bat.

---

Update: push.autoSetupRemote now solves this in an easier way, finally! See the other answer on that here for more information.

Original answer:

I use this Git alias instead of copy/pasting the suggestion from Git every time: https://gist.github.com/ekilah/88a880c84a50b73bd306

Source copied below (add this to your ~/.gitconfig file):

[alias]
  pushup = "!gitbranchname() { git symbolic-ref --short HEAD; }; gitpushupstream() { git push --set-upstream origin `gitbranchname`; }; gitpushupstream"

---

You can also explicitly tell git pull what remote branch to pull (as it mentions in the error message):

git pull <remote-name> <remote-branch>

Be careful with this, however: if you are on a different branch and do an explicit pull, the refspec you pull will be merged into the branch you're on!

---

git branch --set-upstream-to=origin/master<branch_name>

---

You can set up a really good alias that can handle this without the overly verbose syntax.

I have the following alias in ~/.gitconfig:

po = "!git push -u origin \"$(git rev-parse --abbrev-ref HEAD)\""

After making a commit on a new branch, you can push your new branch by simply typing the command:

git po

---

I did something similar to a lot of other users but wanted to share it as an alternative since I didn't see anyone else post this.

alias gpu='git push --set-upstream origin $(git branch --show-current)'

(oh-my-zsh already has a gpu alias so edited that in .oh-my-zsh/plugins/git/git.plugin.zsh)

---

For those looking for an alias that works with git pull, this is what I use:

alias up="git branch | awk '/^\\* / { print \$2 }' | xargs -I {} git branch --set-upstream-to=origin/{} {}"

Now whenever you get:

$ git pull
There is no tracking information for the current branch.
...

Just run:

$ up
Branch my_branch set up to track remote branch my_branch from origin.
$ git pull

And you're good to go

---

99% of the time I want to set the upstream to a branch of the same name, so I use this (in *nix or Git Bash):

git branch --set-upstream-to=origin/$(git branch --show-current)

It's nice because it's branch agnostic. Note the sub-command git branch --show-current prints your current branch name, or nothing if you are detached.

Side note: I have my config set such that I can use git push -u, so I rarely need to do this. But I still do sometimes, and it's usually when I decide I want to reset my local changes to whatever's on the remote, and at that moment I realize I previously pushed without -u. So, typically the next command I'm going to run after setting my upstream, is resetting to the remote branch:

git reset --hard @{u}

Which also happens to be branch agnostic. (Maybe I just really dislike typing in my branch name.)

---

oh-my-zsh's git plugin already has this aliased as gpsup. This pushes and sets the upstream to the branch. All in one go!

I personally dig solutions that are standardized and consistent. Would recommend others to use the same alias. :)

---

In git 2.37.0 or newer, you can tell git to automatically setup the remote. This is done with

git config --global --add --bool push.autoSetupRemote true

Then you can just write git push and it will push to the default remote.

---

Because git has the cool ability to push/pull different branches to different "upstream" repositories. You could even use separate repositories for pushing and pulling - on the same branch. This can create a distributed, multi-level flow, I can see this being useful on project such as the Linux kernel. Git was originally built to be used on that project.

As a consequence, it does not make assumption about which repo your branch should be tracking.

On the other hand, most people do not use git in this way, so it might make a good case for a default option.

Git is generally pretty low-level and it can be frustrating. Yet there are GUIs and it should be easy to write helper scripts if you still want to use it from the shell.

---

You can also do git push -u origin $(current_branch)

---

We use phabricator and don't push using git. I had to create bash alias which works on Linux/mac

vim ~/.bash_aliases

new_branch() {
    git checkout -b "$1"
    git branch --set-upstream-to=origin/master "$1"
}

save

source ~/.bash_aliases
new_branch test #instead of git checkout -b test
git pull

---

Here is a bash alias for git push which is safe to run for every push and will automatically switch between setting upstream for the first push and then doing normal pushes after that.

alias gpu='[[ -z $(git config "branch.$(git symbolic-ref --short HEAD).merge") ]] && git push -u origin $(git symbolic-ref --short HEAD) || git push'

Original Post

---

All i wanted was doing something like this:

git checkout -b my-branch
git commit -a -m "my commit"
git push

Since i didn't found a better solution, i've just created an bash alias on ~/.bashrc:

alias push="git push -u origin HEAD"

now just doing a push command does the job (you can add this alias on ~/.gitconfig too with another name, such as pushup)

---

I sort of re-discovered legit because of this issue (OS X only). Now all I use when branching are these two commands:

legit publish [<branch>] Publishes specified branch to the remote. (alias: pub)

legit unpublish <branch> Removes specified branch from the remote. (alias: unp)

SublimeGit comes with legit support by default, which makes whole branching routine as easy as pressing Ctrl-b.

---

There are a lot of good answers here, however, all of them require you to do something else correctly before running git pull

It certainly helps to have aliases that do things like "make git push work the way it ought to, by creating a remote branch that the local is properly tracking". However, none of that helps you when you forget to use them, or went through a different workflow.

Here is a bash function that you can use to do a pull the way it ought to work, by detecting when you don't have a remote merge target configured, but there is a branch on the remote with the same name as your local branch, and setting that branch as the merge target, then pulling.

git-pulldown() {
    head="$(git rev-parse --abbrev-ref HEAD)"

    if [[ $(git config "branch.$head.merge") ]]; then #there's already a merge target configured, just pull as normal from there
        git pull
    else
        if [[ $(git ls-remote --heads origin $head) ]]; then #there is an upstream branch existing with the same name as our branch
            git branch --set-upstream-to origin/$head #set merge target to upstream branch with same name
            git pull
        else #fail with explanation
            echo "Branch $head has no upstream or merge target! You will likely have to push first, or manually configure it"
            return 1
        fi
    fi
}

---

There is apparently no supported way to override default options of git commands. Based on this answer to Define git alias with the same name to shadow original command, we can override the behavior of git push in bash to always call git push -u. Put the following in your ~/.bash_profile file, and it should be equivalent to running --set-upstream every time you push.

function do_git {
  cmd=$1
  shift
  myArgs=( "$@" )

  if [ "$cmd" == "push" ]; then
    myArgs=( "-u" "${myArgs[@]}" )
  fi
  myArgs=( "$cmd" "${myArgs[@]}" )

  $(which git) "${myArgs[@]}"
}
alias  git='do_git'
