Is it possible to pull just one file in Git?

I am working on a Git branch that has some broken tests, and I would like to pull (merge changes, not just overwrite) these tests from another branch where they are already fixed.

I know I can do

git pull origin that_other_branch

but this will attempt to merge lots of other files, for that I am not yet ready.

Is it possible to pull and merge only the specified file (and not everything) from that another branch?

This is not a duplicate of Git pull request for just one file as all answers to that question are how to revert the locally changed file to the repository version, without changing any branches.

Here is a slightly easier method I just came up with when researching this:

git fetch {remote}
git checkout FETCH_HEAD -- {file}

fatal: invalid reference: FETCH_HEAD
This answer possibly lacks a working example. It is unclear if one needs to commit next.
@Chris do we need {remote} if we are already in Branch? If yes, why?
Not the same as pull, which will attempt a merge, which is why we want to use pull.

You can fetch and then check out only one file in this way:

git fetch
git checkout -m <revision> <yourfilepath>
git add <yourfilepath>
git commit

Regarding the git checkout command:

-- a branch name, i.e. origin/master

does not include the repository name (that you can get from clicking copy path button on a file page on GitHub), i.e. README.md


The hash codes required by -m switch can be printed with git branch -v . Awesome!
Excellent. This has helped me on more than one occasion. To clarify, the -m flag seems to be happy with the hash of the commit from which you want to pull your single file.
This worked for me as well. Though, I ran git log on my remote branch to find the reversion: e.g. $ git log remotes/origin/master
Is it possible to pull specific file without pulling other files ?
@aleroot what does stands for?

git checkout master -- myplugin.js

master = branch name myplugin.js = file name


and is there a way to revert back?
don't forget to 'git pull' before ;)

@Mawardy's answer worked for me, but my changes were on the remote so I had to specify the origin

git checkout origin/master -- {filename}

Yes, here is the process:

# Navigate to a directory and initiate a local repository
git init        

# Add remote repository to be tracked for changes:   
git remote add origin https://github.com/username/repository_name.git

# Track all changes made on above remote repository
# This will show files on remote repository not available on local repository
git fetch

# Add file present in staging area for checkout
git check origin/master -m /path/to/file
# NOTE: /path/to/file is a relative path from repository_name
git add /path/to/file

# Verify track of file(s) being committed to local repository
git status

# Commit to local repository
git commit -m "commit message"

# You may perform a final check of the staging area again with git status

I missed the git checkout line because it's hidden between comments. Also, this says "git check" rather than "git checkout".

In order to overwrite the local file with the file from some other repo or branch, the command is...

git checkout remoteName/branchName filePath

Here is an example I previously used...

git checkout origin/master package-lock.json
