git Pull ...) Before Pushing Again.
git push
The git button command is used to upload local repository content to a remote repository. Pushing is how yous transfer commits from your local repository to a remote repo. Information technology's the counterpart to git fetch, but whereas fetching imports commits to local branches, pushing exports commits to remote branches. Remote branches are configured using the git remote command. Pushing has the potential to overwrite changes, circumspection should be taken when pushing. These problems are discussed below.
Git push usage
git push <remote> <co-operative> Push the specified branch to
git push <remote> --force Same as the above command, but force the push even if it results in a non-fast-forward merge. Practise non apply the --force flag unless you're admittedly sure you lot know what you're doing.
Push all of your local branches to the specified remote.
Tags are not automatically pushed when you lot push a branch or use the --all pick. The --tags flag sends all of your local tags to the remote repository.
Git push discussion
git button is well-nigh commonly used to publish an upload local changes to a central repository. After a local repository has been modified a push is executed to share the modifications with remote team members.
The above diagram shows what happens when your local chief has progressed past the key repository's main and you publish changes past running git push origin primary. Notice how git button is essentially the same as running git merge main from inside the remote repository.
Git push and syncing
git button is ane component of many used in the overall Git "syncing" process. The syncing commands operate on remote branches which are configured using the git remote command. git button can be considered and 'upload' command whereas, git fetch and git pull can be thought of as 'download' commands. Once changesets have been moved via a download or upload a git merge may be performed at the destination to integrate the changes.
Pushing to bare repositories
A frequently used, modern Git exercise is to have a remotely hosted --bare repository act as a cardinal origin repository. This origin repository is oftentimes hosted off-site with a trusted 3rd party like Bitbucket. Since pushing messes with the remote branch structure, Information technology is safest and near common to push to repositories that accept been created with the --bare flag. Bare repos don't have a working directory then a push will non change whatsoever in progress working directory content. For more information on bare repository creation, read virtually git init.
Force Pushing
Git prevents you from overwriting the central repository's history by refusing push requests when they result in a not-fast-forrad merge. Then, if the remote history has diverged from your history, you need to pull the remote branch and merge information technology into your local 1, and then try pushing once more. This is like to how SVN makes y'all synchronize with the primal repository via svn update earlier committing a changeset.
The --forcefulness flag overrides this behavior and makes the remote repository'due south co-operative match your local one, deleting any upstream changes that may accept occurred since you concluding pulled. The only time you should ever need to force push is when you realize that the commits y'all just shared were not quite correct and you lot fixed them with a git commit --meliorate or an interactive rebase. However, y'all must be absolutely certain that none of your teammates take pulled those commits before using the --force option.
Examples
Default git push
The following example describes one of the standard methods for publishing local contributions to the central repository. Kickoff, it makes sure your local principal is up-to-date past fetching the cardinal repository's copy and rebasing your changes on peak of them. The interactive rebase is also a adept opportunity to clean upwardly your commits before sharing them. Then, the git push command sends all of the commits on your local master to the central repository.
git checkout primary
git fetch origin principal
git rebase -i origin/main
# Squash commits, fix upward commit letters etc.
git push origin main Since nosotros already made sure the local main was up-to-date, this should result in a fast-forward merge, and git button should not complain about whatever of the non-fast-forward issues discussed above.
Amended strength push
The git commit command accepts a --amend selection which volition update the previous commit. A commit is often amended to update the commit bulletin or add new changes. Once a commit is amended a git button will fail because Git will see the amended commit and the remote commit as diverged content. The --strength option must be used to button an amended commit.
# brand changes to a repo and git add
git commit --meliorate
# update the existing commit message
git push --force origin chief The in a higher place example assumes it is being executed on an existing repository with a commit history. git commit --amend is used to update the previous commit. The amended commit is then force pushed using the --force option.
Deleting a remote branch or tag
Sometimes branches need to be cleaned up for book keeping or organizational purposes. The fully delete a branch, information technology must exist deleted locally and besides remotely.
git branch -D branch_name
git push origin :branch_name The to a higher place will delete the remote branch named branch_name passing a branch name prefixed with a colon to git push button will delete the remote co-operative.
