How do I checkout just one file from a git repo?
Originally, I mentioned in 2012 git archive (see Jared Forsyth's answer and Robert Knight's answer), since git1.7.9.5 (March 2012), Paul Brannan's answer:
git archive --format=tar --remote=origin HEAD:path/to/directory -- filename | tar -O -xf -
But: in 2013, that was no longer possible for remote https://github.com URLs.
See the old page "Can I archive a repository?"
The current (2018) page "About archiving content and data on GitHub" recommends using third-party services like GHTorrent or GH Archive.
So you can also deal with local copies/clone:
You could alternatively do the following if you have a local copy of the bare repository as mentioned in this answer,
git --no-pager --git-dir /path/to/bar/repo.git show branch:path/to/file >file
Or you must clone first the repo, meaning you get the full history:
in the .git repo
in the working tree.
But then you can do a sparse checkout (if you are using Git1.7+),:
enable the sparse checkout option (git config core.sparsecheckout true)
adding what you want to see in the .git/info/sparse-checkout file
re-reading the working tree to only display what you need
To re-read the working tree:
$ git read-tree -m -u HEAD
That way, you end up with a working tree including precisely what you want (even if it is only one file)
Richard Gomes points (in the comments) to "How do I clone, fetch or sparse checkout a single directory or a list of directories from git repository?"
A bash function which avoids downloading the history, which retrieves a single branch and which retrieves a list of files or directories you need.
With Git 2.40 (Q1 2023), the logic to see if we are using the "cone" mode by checking the sparsity patterns has been tightened to avoid mistaking a pattern that names a single file as specifying a cone.
See commit 5842710 (03 Jan 2023) by William Sprent (williams-unity).
(Merged by Junio C Hamano -- gitster -- in commit ab85a7d, 16 Jan 2023)
dir: check for single file cone patterns
Signed-off-by: William Sprent
Acked-by: Victoria Dye
The sparse checkout documentation states that the cone mode pattern set is limited to patterns that either recursively include directories or patterns that match all files in a directory.
In the sparse checkout file, the former manifest in the form:
/A/B/C/
while the latter become a pair of patterns either in the form:
/A/B/
!/A/B/*/
or in the special case of matching the toplevel files:
/*
!/*/
The 'add_pattern_to_hashsets()' function contains checks which serve to disable cone-mode when non-cone patterns are encountered.
However, these do not catch when the pattern list attempts to match a single file or directory, e.g. a pattern in the form:
/A/B/C
This causes sparse-checkout to exhibit unexpected behaviour when such a pattern is in the sparse-checkout file and cone mode is enabled.
Concretely, with the pattern like the above, sparse-checkout, in non-cone mode, will only include the directory or file located at '/A/B/C'.
However, with cone mode enabled, sparse-checkout will instead just manifest the toplevel files but not any file located at '/A/B/C'.
Relatedly, issues occur when supplying the same kind of filter when partial cloning with '--filter=sparse:oid=<oid>'.
'upload-pack' will correctly just include the objects that match the non-cone pattern matching.
Which means that checking out the newly cloned repo with the same filter, but with cone mode enabled, fails due to missing objects.
To fix these issues, add a cone mode pattern check that asserts that every pattern is either a directory match or the pattern '/*'.
Add a test to verify the new pattern check and modify another to reflect that non-directory patterns are caught earlier.
First clone the repo with the -n option, which suppresses the default checkout of all files, and the --depth 1 option, which means it only gets the most recent revision of each file
git clone -n git://path/to/the_repo.git --depth 1
Then check out just the file you want like so:
cd the_repo
git checkout HEAD name_of_file
If you already have a copy of the git repo, you can always checkout a version of a file using a git log to find out the hash-id (for example 3cdc61015724f9965575ba954c8cd4232c8b42e4) and then you simply type:
git checkout hash-id path-to-file
Here is an actual example:
git checkout 3cdc61015724f9965575ba954c8cd4232c8b42e4 /var/www/css/page.css
Normally it's not possible to download just one file from git without downloading the whole repository as suggested in the first answer.
It's because Git doesn't store files as you think (as CVS/SVN do), but it generates them based on the entire history of the project.
But there are some workarounds for specific cases. Examples below with placeholders for user, project, branch, filename.
GitHub
wget https://raw.githubusercontent.com/user/project/branch/filename
GitLab
wget https://gitlab.com/user/project/raw/branch/filename
GitWeb
If you're using Git on the Server - GitWeb, then you may try in example (change it into the right path):
wget "http://example.com/gitweb/?p=example;a=blob_plain;f=README.txt;hb=HEAD"
GitWeb at drupalcode.org
Example:
wget "http://drupalcode.org/project/ads.git/blob_plain/refs/heads/master:/README.md"
googlesource.com
There is an undocumented feature that allows you to download base64-encoded versions of raw files:
curl "https://chromium.googlesource.com/chromium/src/net/+/master/http/transport_security_state_static.json?format=TEXT" | base64 --decode
In other cases check if your Git repository is using any web interfaces.
If it's not using any web interface, you may consider to push your code to external services such as GitHub, Bitbucket, etc. and use it as a mirror.
If you don't have wget installed, try curl -O (url) alternatively.
Minimal Guide
git checkout -- <filename>
Ref: https://git-scm.com/docs/git-checkout
Dup: Undo working copy modifications of one file in Git?
git checkout branch_or_version -- path/file
example: git checkout HEAD -- main.c
Now we can! As this is the first result on google, I thought I'd update this to the latest standing. With the advent of git 1.7.9.5, we have the git archive command which will allow you to retrieve a single file from a remote host.
git archive --remote=git://git.foo.com/project.git HEAD:path/in/repo filename | tar -x
See answer in full here https://stackoverflow.com/a/5324532/290784
Here is the complete solution for pulling and pushing only a particular file inside git repository:
First you need to clone git repository with a special hint –no checkout
git clone --no-checkout <git url>
The next step is to get rid of unstaged files in the index with the command:
git reset
Now you are allowed to start pulling files you want to change with the command:
git checkout origin/master <path to file>
Now the repository folder contains files that you may start editing right away. After editing you need to execute plain and familar sequence of commands.
git add <path to file>
git commit -m <message text>
git push
Working in GIT 1.7.2.2
For example you have a remote some_remote with branches branch1, branch32
so to checkout a specific file you call this commands:
git checkout remote/branch path/to/file
as an example it will be something like this
git checkout some_remote/branch32 conf/en/myscript.conf
git checkout some_remote/branch1 conf/fr/load.wav
This checkout command will copy the whole file structure conf/en and conf/fr into the current directory where you call these commands (of course I assume you ran git init at some point before)
Very simple:
git checkout from-branch-name -- path/to/the/file/you/want
This will not checkout the from-branch-name branch. You will stay on whatever branch you are on, and only that single file will be checked out from the specified branch.
Here's the relevant part of the manpage for git-checkout
git checkout [-p|--patch] [<tree-ish>] [--] <pathspec>...
When <paths> or --patch are given, git checkout does not switch
branches. It updates the named paths in the working tree from the
index file or from a named <tree-ish> (most often a commit). In
this case, the -b and --track options are meaningless and giving
either of them results in an error. The <tree-ish> argument can be
used to specify a specific tree-ish (i.e. commit, tag or tree) to
update the index for the given paths before updating the working
tree.
Hat tip to Ariejan de Vroom who taught me this from this blog post.
git clone --filter from Git 2.19
This option will actually skip fetching most unneeded objects from the server:
git clone --depth 1 --no-checkout --filter=blob:none \
"file://$(pwd)/server_repo" local_repo
cd local_repo
git checkout master -- mydir/myfile
The server should be configured with:
git config --local uploadpack.allowfilter 1
git config --local uploadpack.allowanysha1inwant 1
There is no server support as of v2.19.0, but it can already be locally tested.
TODO: --filter=blob:none skips all blobs, but still fetches all tree objects. But on a normal repo, this should be tiny compared to the files themselves, so this is already good enough. Asked at: https://www.spinics.net/lists/git/msg342006.html Devs replied a --filter=tree:0 is in the works to do that.
Remember that --depth 1 already implies --single-branch, see also: How do I clone a single branch in Git?
file://$(path) is required to overcome git clone protocol shenanigans: How to shallow clone a local git repository with a relative path?
The format of --filter is documented on man git-rev-list.
An extension was made to the Git remote protocol to support this feature.

Conclusions: all blobs except d1/a are missing. E.g. f70a17f51b7b30fec48a32e4f19ac15e261fd1a4, which is d1/b, is not there after checking out d1/.
Note that root/root and mybranch/mybranch are also missing, but --depth 1 hides that from the list of missing files. If you remove --depth 1, then they show on the list of missing files.
Two variants on what's already been given:
git archive --format=tar --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | tar -O -xf -
and:
git archive --format=zip --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | funzip
These write the file to standard output.
You can do it by
git archive --format=tar --remote=origin HEAD | tar xf -
git archive --format=tar --remote=origin HEAD <file> | tar xf -
Say the file name is 123.txt, this works for me:
git checkout --theirs 123.txt
If the file is inside a directory A, make sure to specify it correctly:
git checkout --theirs "A/123.txt"
In git you do not 'checkout' files before you update them - it seems like this is what you are after.
Many systems like clearcase, csv and so on require you to 'checkout' a file before you can make changes to it. Git does not require this. You clone a repository and then make changes in your local copy of repository.
Once you updated files you can do:
git status
To see what files have been modified. You add the ones you want to commit to index first with (index is like a list to be checked in):
git add .
or
git add blah.c
Then do git status will show you which files were modified and which are in index ready to be commited or checked in.
To commit files to your copy of repository do:
git commit -a -m "commit message here"
See git website for links to manuals and guides.
If you need a specific file from a specific branch from a remote Git repository the command is:
git archive --remote=git://git.example.com/project.git refs/heads/mybranch path/to/myfile |tar xf -
The rest can be derived from #VonC's answer:
If you need a specific file from the master branch it is:
git archive --remote=git://git.example.com/project.git HEAD path/to/myfile |tar xf -
If you need a specific file from a tag it is:
git archive --remote=git://git.example.com/project.git mytag path/to/myfile |tar xf -
this works for me. use git with some shell command
git clone --no-checkout --depth 1 git.example.com/project.git && cd project && git show HEAD:path/to/file_you_need > ../file_you_need && cd .. && rm -rf project
Another solution, similar to the one using --filter=blob:none is to use --filter=tree:0 (you can read an explanation about the differences here).
This method is usually faster than the blob-one because it doesn't download the tree structure, but has a drawback. Given you are delaying the retrieval of the tree, you will have a penalty when you enter into the repo directory (depending on the size and structure of your repo it may be many times larger compared with a simple shallow-clone).
If that's the case for you, you can fix it by not entering into the repo:
git clone -n --filter=tree:0 <repo_url> tgt_dir
git -C tgt_dir checkout <branch> -- <filename>
cat tgt_dir/<filename> # or move it to another place and delete tgt_dir ;)
Take into consideration that if you have to checkout multiple files, the tree population will also impact your performance, so I recommend this for a single file and only if the repo is large enough to be worth it all these actions.
It sounds like you're trying to carry over an idea from centralized version control, which git by nature is not - it's distributed. If you want to work with a git repository, you clone it. You then have all of the contents of the work tree, and all of the history (well, at least everything leading up to the tip of the current branch), not just a single file or a snapshot from a single commit.
git clone /path/to/repo
git clone git://url/of/repo
git clone http://url/of/repo
I am adding this answer as an alternative to doing a formal checkout or some similar local operation. Assuming that you have access to the web interface of your Git provider, you might be able to directly view any file at a given desired commit. For example, on GitHub you may use something like:
https://github.com/hubotio/hubot/blob/ed25584f/src/adapter.coffee
Here ed25584f is the first 8 characters from the SHA-1 hash of the commit of interest, followed by the path to the source file.
Similary, on Bitbucket we can try:
https://bitbucket.org/cofarrell/stash-browse-code-plugin/src/06befe08
In this case, we place the commit hash at the end of the source URL.
In codecommit (git version of Amazon AWS) you can do this:
aws codecommit \
get-file --repository-name myrepo \
--commit-specifier master \
--file-path path/myfile \
--output text \
--query fileContent |
base64 --decode > myfile
I don’t see what worked for me listed out here so I will include it should anybody be in my situation.
My situation, I have a remote repository of maybe 10,000 files and I need to build an RPM file for my Linux system. The build of the RPM includes a git clone of everything. All I need is one file to start the RPM build. I can clone the entire source tree which does what I need but it takes an extra two minutes to download all those files when all I need is one. I tried to use the git archive option discussed and I got “fatal: Operation not supported by protocol.” It seems I have to get some sort of archive option enabled on the server and my server is maintained by bureaucratic thugs that seem to enjoy making it difficult to get things done.
What I finally did was I went into the web interface for bitbucket and viewed the one file I needed. I did a right click on the link to download a raw copy of the file and selected “copy shortcut” from the resulting popup. I could not just download the raw file because I needed to automate things and I don’t have a browser interface on my Linux server.
For the sake of discussion, that resulted in the URL:
https://ourArchive.ourCompany.com/projects/ThisProject/repos/data/raw/foo/bar.spec?at=refs%2Fheads%2FTheBranchOfInterest
I could not directly download this file from the bitbucket repository because I needed to sign in first. After a little digging, I found this worked:
On Linux:
echo "myUser:myPass123"| base64
bXlVc2VyOm15UGFzczEyMwo=
curl -H 'Authorization: Basic bXlVc2VyOm15UGFzczEyMwo=' 'https://ourArchive.ourCompany.com/projects/ThisProject/repos/data/raw/foo/bar.spec?at=refs%2Fheads%2FTheBranchOfInterest' > bar.spec
This combination allowed me to download the one file I needed to build everything else.
if you have a file, locally changed (the one which messing with git pull) just do:
git checkout origin/master filename
git checkout - switch branches or restore working tree files, (here we switching nothing, just overwriting file
origin/master - your current branch or you can use specific revision-number for example: cd0fa799c582e94e59e5b21e872f5ffe2ad0154b,
filename with path from project main directory (where directory .git lives)
so if you have structure:
`.git
public/index.html
public/css/style.css
vendors
composer.lock`
and want reload index.html - just use public/index.html
Yes you can this by this command which download one specific file
wget -o <DesiredFileName> <Git FilePath>\?token\=<personalGitToken>
example
wget -o javascript-test-automation.md https://github.com/akashgupta03/awesome-test-automation/blob/master/javascript-test-automation.md\?token\=<githubPersonalTone>
git checkout <other-branch> -- <single-file> works for me on git.2.37.1.
However, the file is (git-magically) staged for commit and I can not see git diff properly.
I then run git restore --staged db/structure.sql to unstage it.
That way I DO have the file in the exact version that I want and I can see the difference with other versions of that file.
If you have edited a local version of a file and wish to revert to the original version maintained on the central server, this can be easily achieved using Git Extensions.
Initially the file will be marked for commit, since it has been modified
Select (double click) the file in the file tree menu
The revision tree for the single file is listed.
Select the top/HEAD of the tree and right click save as
Save the file to overwrite the modified local version of the file
The file now has the correct version and will no longer be marked for commit!
Easy!
If you only need to download the file, no need to check out with Git.
GitHub Mate is much easier to do so, it's a Chrome extension, enables you click the file icon to download it. also open source
I have the most simple script called update.sh
#!/bin/sh
cd /home/pi/circulation_of_circuits
git pull
When I call this from the terminal with ./update.sh I get a Already up-to-date or it updates the files like expected.
I also have a python script, inside that scipt is:
subprocess.call(['./update.sh'])
When that calls the same script I get:
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
(I use SSH).
----------------- update --------------------
Someone else had a look for me:
OK so some progress. When I boot your image I can't run git pull in
your repo directory and the bash script also fails. It seems to be
because the bitbucket repository is private and needs authentication
for pull (the one I was using was public so that's why I had no
issues). Presumably git remembers this after you type it in the first
time, bash somehow tricks git into thinking it's you typing the
command subsequently but running it from python isn't the same.
I'm not a git expert but there must be some way of setting this up so
python can provide the authentication.
sounds like you need to give your ssh command a public or private key it can access perhaps:
ssh -i /backup/home/user/.ssh/id_dsa user#unixserver1.nixcraft.com
-i tells it where to look for the key
This problem is caused by the git repo authentication failing. You say you are using SSH, and git is complaining about publickey auth failing. Normally you can use git commands on a private repo without inputting a password. All this would imply that git is using ssh, but in the latter case it cannot find the correct private key.
Since the problem only manifests itself when run through another script, it is very likely caused by something messing with the environment variables. Subprocess.call should pass the environment as is, so there are a couple of usual suspects:
sudo.
if you are using sudo, it will pass a mostly empty environment to the process
the python script itself
if the python script changes its env, those changes will get propagated to the subprocess too.
sh -lor su -
these commands set up a login shell, which means their environment gets reset to defaults.
Any of these reasons could hide the environment variables ssh-agent (or some other key management tool) might need to work.
Steps to diagnose and fix:
Isolate the problem.
Create a minimal python script that does nothing else than runs subprocess.call(['./update.sh']). Run both update.sh and the new script.
Diagnose the problem and fix accordingly:
a) If update.sh works, and the new script doesn't, you are probably experiencing some weird corner case of system misconfiguration. Try upgrading your system and python; if the problem persists, it probably requires additional debugging on the affected system itself.
b) If both update.sh and the new script work, then the problem lies within the outer python script calling the shell script. Look for occurrences of sudo, su -, sh -l, env and os.environ, one of those is the most likely culprit.
c) If neither the update.sh nor the new script work, your problem is likely to be with ssh client configuration; a typical cause would be that you are using a non-default identity, did not configure it in ~/.ssh/config but used ssh-add instead, and after that, ssh-agent's cache expired. In this case, run ssh-add identityfile for the identity you used to authenticate to that git repo, and try again.
I believe this answer will help you: https://serverfault.com/questions/497217/automate-git-pull-stuck-with-keychain?answertab=votes#tab-top
I didn't use ssh-agent and it worked: Change your script to the one that follows and try.
#!/bin/bash
cd /home/pi/circulation_of_circuits
ssh-add /home/yourHomefolderName/.ssh/id_rsa
ssh-add -l
git pull
This assumes that you have configured correctly your ssh key.
It seems like your version control system, need the authentication for the pull so can build the python with use of pexpect,
import pexpect
child = pexpect.spawn('./update.sh')
child.expect('Password:')
child.sendline('SuperSecretPassword')
Try using the sh package instead of using the subprocess call. https://pypi.python.org/pypi/sh
I tried this snippet and it worked for me.
#!/usr/local/bin/python
import sh
sh.cd("/Users/siyer/workspace/scripts")
print sh.git("pull")
Output:
Already up-to-date.
import subprocess
subprocess.call("sh update.sh", shell=True)
With Git 1.7.9 or later, you can just use one of the following credential helpers:
With a timeout
git config --global credential.helper cache
... which tells Git to keep your password cached in memory for (by default) 15 minutes. You can set a longer timeout with:
git config --global credential.helper "cache --timeout=3600"
(That example was suggested in the GitHub help page for Linux.) You can also store your credentials permanently if so desired.
Saving indefinitely
You can use the git-credential-store via
git config credential.helper store
GitHub's help also suggests that if you're on Mac OS X and used Homebrew to install Git, you can use the native Mac OS X keystore with:
git config --global credential.helper osxkeychain
For Windows, there is a helper called Git Credential Manager for Windows or wincred in msysgit.
git config --global credential.helper wincred # obsolete
With Git for Windows 2.7.3+ (March 2016):
git config --global credential.helper manager
For Linux, you can use gnome-keyring(or other keyring implementation such as KWallet).
Finally, after executing one of the suggested command one time manually, you can execute your script without changes in it.
I can reproduce your fault. It has nothing to do with permission, it depends how your ssh are installed on your system. To verify it's the same cause i need the diff output.
Save the following to a file log_shell_env.sh,
#!/bin/bash
log="shell_env"$1
echo "create shell_env"$1
echo "shell_env" > $log
echo "whoami="$(whoami) >> $log
echo "which git="$(which git) >> $log
echo "git status="$(git status 2>&1) >> $log
echo "git pull="$(git pull 2>&1) >> $log
echo "ssh -vT git#github.com="$(ssh -T git#github.com 2>&1) >> $log
echo "ssh -V="$(ssh -V 2>&1) >> $log
echo "ls -al ~/.ssh="$(ls -a ~/.ssh) >> $log
echo "which ssh-askpass="$(which ssh-askpass) >> $log
echo "ps -e | grep [s]sh-agent="$(ps -e | grep [s]sh-agent ) >> $log
echo "ssh-add -l="$(ssh-add -l) >> $log
echo "set=" >> $log
set >> $log
set execute permission and run it twice:
1. From the console without parameter
2. From your python script with parameter '.python'
Please, run it realy from the same python script!
For instance:
try:
output= subprocess.check_output(['./log_shell_env.sh', '.python'], stderr=subprocess.STDOUT)
print(output.decode('utf-8'))
except subprocess.CalledProcessError as cpe:
print('[ERROR] check_output: %s' % cpe)
Do a diff shell_env shell_env.python > shell_env.diff
The resulting shell_env.diff should show not more than the following diffs:
15,16c15,16
< BASH_ARGC=()
< BASH_ARGV=()
---
> BASH_ARGC=([0]="1")
> BASH_ARGV=([0]=".python")
48c48
< PPID=2209
---
> PPID=2220
72c72
< log=shell_env
---
> log=shell_env.python
Come back and comment, if you get more diffs
update your Question with the diff output.
Use the following python code. This will import the os module in python and make a system call with sudo permissions.
#!/bin/python
import os
os.system("sudo ./update.sh")
