    How to Clone Only a Subdirectory with Git or SVN

    Git is already possible, but SVN is much simpler.

    How to Clone Only a Subdirectory with Git or SVN

    In this tip I will show something that seems simple (in Git), but it is very complicated! =) Because I actually created a Shell Script that you can run as a command in your $PATH.

    I will also provide one more solution, but not from Git but from SVN, which to be honest , I would not even need a Shell function, but to make it even easier I will also show.

    To understand this article you must have basic knowledge of Git and GitHub or any other Git repository.

    For that I recommend you to know our specific Git and GitHub beginner page: https://terminalroot.com.br/git. There you’ll find text and video tips, including a [Git and GitHub for Beginners] mini course (https://www.youtube.com/watch?v=CsyumQN6ZdA&list=PLUJBQEDDLNclXAjLaiPWakoO9VosPDzC1).

    Introduction

    In short, cloning a repository means: copying all its files to your computer.

    git clone is a Git command line utility that is used to direct an existing repository and create a clone or copy of the destination repository. It is very simple to clone Git repositories: GitHub, GitLab, BitBucket and others.

    The command summarizes in:

    git clone [repository]

    For example, I have a repository that is https://github.com/terroo/fonts, assuming you want to clone this repository, the command would be:

    git clone https://github.com/terroo/fonts

    You can still clone already renaming and/or with the same name in a new path of your computer, example:

    1. Clone with a new name: new-fonts:

    git clone https://github.com/terroo/fonts new-fonts
    1. Clone with a new name within the Downloads directory:
    git clone https://github.com/terroo/fonts Downloas/new sources

    Or even clone with the same name in another path:

    git clone https://github.com/terroo/fonts Downloads/fonts

    Note: If you enter a new path, you must enter a name, either the same name or a new one. If you do so, without entering a name, it will report an error: fatal: destination path 'Downloads' already exists and is not an empty directory..

    In addition there are several parameters you can use, here we will see a few, but you can get the full documentation on the official Git website more specifically at the URL: https://git-scm.com/docs/git-clone.

    Cloning a Subdirectory

    This repository that I used as an example was totally poorly designed, there you will not only find fonts, but also: Wallpapers, WM configuration files and other things. And because of that, sometimes I want to copy only one * sub directory * into it.

    For example, in this repository there is a folder/directory named files and let’s suppose I want to copy/clone only this directory/sub-directory if I do this: git clone https://github.com/terroo/fonts/files will not work, Git will not allow it, clone will fail:

    marcos@gentoo ~ $ git clone https://github.com/terroo/fonts/files
Cloning into 'files' ...
remote: Not Found
fatal: repository 'https://github.com/terroo/fonts/files/' not found
marcos@gentoo ~ $

    And it’s quite inconvenient for you to clone the entire repository (which by the way is quite large) which will take a long time just to use files from a specific repository directory.

    Until Git 2.18 this was not possible, but as of 2.19 it is already possible, so check your Git version before proceeding, use the git --version command to know the version. If it is equal to or greater than 2.19 you can clone only a specific directory.

    To clone this directory (files, inside the repository) we will use the following commands, explanation in the comments (#):

    # Create a directory, so Git doesn't get messy, and enter it
mkdir my-dir && cd my-dir

# Start a Git repository
git init

# Track repository, do not enter subdirectory
git remote add -f origin https://github.com/terroo/fonts/

# Enable the tree check feature
git config core.sparseCheckout true

# Create a file in the path: .git/info/sparse-checkout
# That is inside the hidden .git directory that was created
# by running the command: git init
# And inside it enter the name of the sub directory you only want to clone
echo 'files' >> .git/info/sparse-checkout

## Download with pull, not clone
git pull origin master

    For each command, if you do not understand well, I recommend you look over the manual, for example: man git remote.

    If you find a lot of process running all these commands, you can use a shell script, as I said to get automatic and run only one command, see the script by clicking the link below:

    📁 git.dir.sh

    If you want to make a command to use in any directory you are in, save it with the name: git-dir (or the name you want) and move it where you want, for example:

    sudo mv git-dir/usr/local/bin/git-dir
# Or if you are a UNIX bugger:
# sudo install -D -v git-dir -t /usr/local/bin/git-dir

    And to use just run git-dir anywhere you are that it will already show help displaying the options.

    Alternative - Using SVN

    Note that when we use Git for this, this clone, despite being from a subdirectory, will still be very slow. For this there is a much faster solution using SVN which is an alternative to the [Apache Software Foundation] Git (https://en.wikipedia.org/wiki/Apache_Software_Foundation).

    The difference between SVN and Git, in my opinion, is summarized in these two images below, that is, there is no better or worse, there is one that meets your specific needs for each case.

    Git SVN

    Apache Subversion (also known as SVN) is a version control system designed specifically to be a modern replacement for CVS, which is considered to have some limitations. Subversion uses Berkeley BD database.

    First of all, you need to have it installed on your system. To do this use your distro’s package manager:

    sudo emerge subversion # Gentoo, Funtoo and Portage baseds
sudo apt-get install subversion # Debian, Ubuntu, Linux Mint APT baseds
sudo pacman -S subversion # Arch Linux, Manjaro and PacMan baseds
sudo yum install subversion # Red Hat, CentOS and YUM baseds
sudo dnf install subversion # Fedora

    And to clone just use the export parameter with fake-dir: trunk between the repository and the subdirectory, example:

    svn export [repository]/trunk/[subdirectory]

    Example for our case:

    svn export https://github.com/terroo/fonts/trunk/files

    If you want it to be your command, simply create a command or add this function to your ~/.bashrc:

    git-svn(){
  if [[ ! -z "$1" && ! -z "$2" ]]; then
          echo "Starting clone/copy ..."
          repo=$(echo $1 | sed 's/\/$\|.git$//')
          svn export "$repo/trunk/$2"
  else
          echo "Use: git-svn <repository> <subdirectory>"
  fi  
}

    In this case I treated the end of the repository name if the user copies with * .git * or with / at the end of the URL name.

    And to use, just run: git-svn [repository] [subdirectory]

    Much simpler, right?

    It is your choice which mode to use. Leave your tips/questions in the comments for us to interact in the solution or discussion on related issues!
