Remote: Total 1 (delta 0), reused 1 (delta 0), pack-reused 0Īnd then the final checkout downloads the files we requested: remote: Enumerating objects: 3, done. Remote: Counting objects: 100% (1/1), done. On the above, git clone downloads a single object, presumably the commit: Cloning into 'test-git-partial-clone-big-small'. So if you download anything you didn't want, you would get 100 MB extra, and it would be very noticeable. a small/ and small2/ subdirectories with 1000 files of size one byte eachĪll contents are pseudo-random and therefore incompressible, so we can easily notice if any of the big files were downloaded, e.g.9 on toplevel (this is because certain previous attempts would download toplevel files) a big/ subdirectory with 10x 10MB files.In this test, clone is basically instantaneous, and we can confirm that the cloned repository is very small as desired: du -apparent-size -hs *. This method doesn't work for individual files however, but here is another method that does: You could also select multiple directories for download with: git sparse-checkout set -no-cone small small2 You must provide your public key to GitHub to establish a secure connection.Git clone -filter + git sparse-checkout downloads only the required filesĮ.g., to clone only files in subdirectory small/ in this test repository: git clone -n -depth=1 -filter=tree:0 \Ĭd test-git-partial-clone-big-small-no-bigtree > debug1: Authentications that can continue: publickey > debug1: Next authentication method: publickey > debug1: Offering RSA public key: /Users/YOU/.ssh/id_rsa Verify the public key is attached to your account > debug1: identity file /Users/YOU/.ssh/id_rsa type 1 >. If a file existed, those lines would be "1" and "Offering public key", respectively: $ ssh -vT >. Later on, the "Trying private key" lines also indicate that no file was found. The "-1" at the end of the "identity file" lines means SSH couldn't find a file to use. In that example, we did not have any keys for SSH to use. > debug1: Authentications that can continue: publickey > debug1: Next authentication method: publickey > debug1: Trying private key: /Users/YOU/.ssh/id_rsa > debug1: Trying private key: /Users/YOU/.ssh/id_dsa > debug1: No more authentication methods to try. > debug1: identity file /Users/YOU/.ssh/id_rsa type -1 > debug1: identity file /Users/YOU/.ssh/id_rsa-cert type -1 > debug1: identity file /Users/YOU/.ssh/id_dsa type -1 > debug1: identity file /Users/YOU/.ssh/id_dsa-cert type -1 >. You can also check that the key is being used by trying to connect to $ ssh -vT >. You shouldn't need to run ssh-add path/to/key unless you override the file name when you generate a key. Tip: On most systems the default private keys ( ~/.ssh/id_rsa and ~/.ssh/identity) are automatically added to the SSH authentication agent. Make sure you have a key that is being used You should verify your connection by typing: $ ssh -T > Hi USERNAME! You 've successfully authenticated. If your connection failed and you're using a remote URL with your GitHub username, you can change the remote URL to use the "git" user. If you try to connect with your GitHub username, it will fail: $ ssh -T > Permission denied (publickey). Always use the "git" userĪll connections, including those for remote URLs, must be made as the "git" user. The connection should be made on port 22, unless you're overriding settings to use SSH over HTTPS. To make sure you are connecting to the right domain, you can enter the following command: $ ssh -vT > OpenSSH_8.1p1, LibreSSL 2.7.3 > debug1: Reading configuration data /Users/YOU/.ssh/config > debug1: Reading configuration data /etc/ssh/ssh_config > debug1: /etc/ssh/ssh_config line 47: Applying options for * > debug1: Connecting to port 22. In some cases, a corporate network may cause issues resolving the DNS record as well. Pay attention to what you type you won't be able to connect to "" or "". Check that you are connecting to the correct server If you generate SSH keys without sudo and then try to use a command like sudo git push, you won't be using the same keys that you generated. If you have a very good reason you must use sudo, then ensure you are using it with every command (it's probably just better to use su to get a shell as root at that point). You should not be using the sudo command or elevated privileges, such as administrator permissions, with Git. Should the sudo command or elevated privileges be used with Git?
