Git Pull
git pull updates your current local working branch, and all of the remote tracking branches. It's a adept idea to run git pull regularly on the branches you lot are working on locally.
Without git pull, (or the effect of information technology,) your local branch wouldn't have any of the updates that are nowadays on the remote.
What Does git pull Do?
git pull is one of the 4 remote operations inside Git. Without running git pull, your local repository volition never exist updated with changes from the remote. git pull should be used every day you interact with a repository with a remote, at the minimum. That'southward why git pull is one of the most used Git commands.
git pull and git fetch
git pull, a combination of git fetch + git merge, updates some parts of your local repository with changes from the remote repository. To understand what is and isn't affected past git pull, you need to starting time empathise the concept of remote tracking branches. When you clone a repository, you clone one working co-operative, main, and all of the remote tracking branches. git fetch updates the remote tracking branches. git merge will update your current branch with whatever new commits on the remote tracking branch.
git pull is the most common fashion to update your repository.
Nonetheless, you may want to use git fetch instead. One reason to practice this may be that you wait conflicts. Conflicts can occur in this mode if you have new local commits, and new commits on the remote. Simply like a merge conflict that would happen between two unlike branches, these two different lines of history could contain changes to the same parts of the aforementioned file. If you commencement operate git fetch, the merge won't be initiated, and you won't be prompted to solve the disharmonize. This gives you lot the flexibility to resolve the disharmonize afterwards without the need of network connectivity.
Another reason y'all may desire to run git fetch is to update to all remote tracking branches before losing network connectivity. If you run git fetch, and then later try to run git pull without any network connectivity, the git fetch portion of the git pull operation will fail.
If you do use git fetch instead of git pull, brand sure you call up to git merge. Merging the remote tracking branch into your own co-operative ensures you volition be working with any updates or changes.
How to Utilise git pull
Common usages and options for git pull
-
git pull: Update your local working branch with commits from the remote, and update all remote tracking branches. -
git pull --rebase: Update your local working branch with commits from the remote, but rewrite history then whatever local commits occur after all new commits coming from the remote, avoiding a merge commit. -
git pull --forcefulness: This option allows you to forcefulness a fetch of a specific remote tracking branch when using the<refspec>option that would otherwise not be fetched due to conflicts. To force Git to overwrite your current branch to match the remote tracking co-operative, read beneath about usinggit reset. -
git pull --all: Fetch all remotes - this is handy if yous are working on a fork or in another use example with multiple remotes.
You can meet all of the many options with git pull in git-scm's documentation.
Examples of git pull
Working on a Branch
If you're already working on a branch, information technology is a good idea to run git pull before starting work and introducing new commits. Fifty-fifty if you take a small-scale break from development, there'south a hazard that one of your collaborators has fabricated changes to your branch. This modify could even come from updating your branch with new changes from main.
Information technology is ever a skillful idea to run git status - especially before git pull. Changes that are not committed tin can be overwritten during a git pull. Or, they can block the git merge portion of the git pull from executing. If you lot have files that are inverse, but not committed, and the changes on the remote also modify those same parts of the same file, Git must make a option. Since they are not committed changes, there is no possibility for a merge conflict. Git will either overwrite the changes in your working or staging directories, or the merge will not complete, and you will not exist able to include any of the updates from the remote.
If this happens, utilise git status to identify what changes are causing the problem. Either delete or commit those changes, then git pull or git merge again.
Keep main up to date
Keeping the master co-operative up to engagement is mostly a good idea.
For case, let'south say you have cloned a repository. Afterward you clone, someone merges a co-operative into main. Then, you lot'd like to create a new branch to do some work. If you create your branch off of main before operating git pull, your branch will not take the most recent changes. You could accidentally introduce a disharmonize, or indistinguishable changes. By running git pull earlier you create a brach, you can exist certain that you will be working with the nearly contempo information.
Undo A git pull
To effectively "undo" a git pull, you cannot undo the git fetch - but you tin can undo the git merge that changed your local working branch.
To do this, you will demand to git reset to the commit you made before yous merged. Y'all can find this commit by searching the git reflog. The reflog is a log of every place that HEAD has pointed - every place that y'all accept always been checked out to. This reflog is merely kept for xxx to 90 days, depending on the commit, and is simply stored locally. (The reflog is a great reason not to delete a repository if you remember y'all've made a mistake!)
Run git reflog and search for the commit that you would similar to render to. Then, run git reset --hard <SHA> to reset HEAD and your current co-operative to the SHA of the commit from before the merge.
Strength git pull to Overwrite Local Files
If you take made commits locally that you regret, yous may want your local branch to match the remote branch without saving any of your work. This tin can be done using git reset. Get-go, make sure you accept the virtually recent re-create of that remote tracking branch past fetching.
git fetch <remote> <branch>
ex: git fetch origin main
Then, use git reset --hard to motion the HEAD pointer and the electric current branch pointer to the nigh recent commit as it exists on that remote tracking co-operative.
git reset --difficult <remote>/<branch>
ex: git reset --hard origin/main
_Note: Yous can find the remotes with
git remote -v, and see all available remote tracking branches withgit branch --all.
git pull with Rebase
If there have been new commits on both your local co-operative and the remote branch, a merge commit will exist created when y'all git pull. This recursive merge is the default merge style when at that place are ii splits in history being brought together. But, yous may want history on a branch to be only 1 line.
Y'all tin update your local working branch with commits from the remote, but rewrite history so any local commits occur after all new commits coming from the remote, avoiding a merge commit.
This is done with git pull --rebase.
Using git pull --rebase does not bear on the integrity of the changes or the commits, but it does touch how history looks in the commit parent/child relationship.
