![]() ![]() If you want to learn more about it, please see the excellent book written by Scott Chacon and available for free. Although when you do, it turns into a very powerful and flexible tool. Git is certainly not an easy tool to learn. prune means we want to delete any reference that may exist there if we don’t have such reference in our refs/remotes/origin/* (and tags) references. The + sign indicates that we want to overwrite any reference there may already exist. The local references there will be stored in the refs/heads dir. ![]() git/refs/remotes/origin to be the LOCAL references in the new location. Now we’re ready to send those updated references back to the origin repository: $ git push -prune +refs/remotes/origin/*:refs/heads/* +refs/tags/*:refs/tags/* Finally, mirroring the repository to a new location This will update your references to the origin repository and also clean the stale branches reported by git branch -r. We need to clean those old references before mirroring them to a new location. Why? Cleaning old references to remote branchesīy default, when you do a git fetch or git pull, git will not delete the references to branches that were deleted in the upstream repository (you may view them in your. If you pay attention to that list, though, you may notice that you have a lot of branches that were already deleted in the upstream repository. It also includes all other branches in that repository. ![]() But you do have references to remote branches. When you clone repositories using a Git clone command, this clones the branch from the master or default. In this case, you may have a lot of local branches and tags that you don’t want to copy to the new location. Mirroring a git repository if you already have a local working copyīy working copy, we mean a “normal” repository, in which you have the files that are being tracked into git and where you perform commands like git add and so on. Read the next section to discover what to do in these cases.Īlso git clone -mirror is preferred over git clone -bare because the former also clones git notes and some other attributes. It’ll overwrite the remote repository with your local references (and your local branches). ![]() Warningĭon’t use git push -mirror in repositories that weren’t cloned by -mirror as well. $ git push -mirror will get all the branches and tags that are available in the upstream repository and will replicate those into the new location. If you haven’t cloned the repository before, you can mirror it to a new home by $ git clone -mirror cd upstream-repository.git Mirroring a git repository without a local copy The difference lays on whether you already have a working copy of that repository or not. You’ll need to do this when migrating your upstream repository to a new “home”, like when switching services like GitHub.Īs with most tools, there’s a lot of ways to accomplish that, but I’ll be focusing on two of them. By state, we mean all the branches (including master) and all the tags as well. However, what we want with mirroring is to replicate the state of an origin repository (or upstream repository). This saves you from having to manually initialize and update the submodules later.When people talk about mirroring a git repository, usually we have a simple answer in mind: If your project contains submodules, using this parameter will make sure that all submodules will both be cloned and initialized once the main project has been cloned. recurse-submodulesĬlones and initializes all contained submodules. As soon as you've linked your GitHub account and authenticated it, a Let's get started window appears, with four promptseach one guiding you on how to create a repository. If this option is not specified, Git will simply create a new folder named after the remote repository. Create and Clone a Repository GitHub Desktop makes it easy for first-time users to navigate the app on their Macs. The name of the folder on your local machine where the repository will be downloaded into. Usually, this will point to a remote server, using a protocol like HTTP, HTTPS, SSH, or GIT. Install Contribute On this page Optimize GitLab for large repositories all tiers Large repositories consisting of more than 50k files in a worktree may require more optimizations beyond pipeline efficiency because of the time required to clone and check out. Specifies the URL of the remote repository. That remote repository's URL is then later referred to as the "origin". Fedora sudo dnf install git CentOS sudo yum install git Arch Linux sudo pacman -Sy git Gentoo sudo emerge -ask -verbose dev-vcs/git How to Install Git on a Mac Download and install the latest Git for Mac installer here. Typically, the "original" repository is located on a remote server, often from a service like GitHub, Bitbucket, or GitLab). You will then have a full-blown, local version of that Git repo and can start working on the project. The "clone" command downloads an existing Git repository to your local computer. ![]()
