When the repository to clone from is on a local machine, this flag bypasses the normal "Git aware" transport mechanism and clones the repository by making a copy of HEAD and everything under objects and refs directories. The files under .git/objects/ directory are hardlinked to save space when possible.

If the repository is specified as a local path (e.g., /path/to/repo), this is the default, and --local is essentially a no-op. If the repository is specified as a URL, then this flag is ignored (and we never use the local optimizations). Specifying --no-local will override the default when /path/to/repo is given, using the regular Git transport instead.

If the repository’s $GIT_DIR/objects has symbolic links or is a symbolic link, the clone will fail. This is a security measure to prevent the unintentional copying of files by dereferencing the symbolic links.

This option does not work with repositories owned by other users for security reasons, and --no-local must be specified for the clone to succeed.

NOTE: this operation can race with concurrent modification to the source repository, similar to running cp -r <src> <dst> while modifying <src>.

Force the cloning process from a repository on a local filesystem to copy the files under the .git/objects directory instead of using hardlinks. This may be desirable if you are trying to make a back-up of your repository.

When the repository to clone is on the local machine, instead of using hard links, automatically setup .git/objects/info/alternates to share the objects with the source repository. The resulting repository starts out without any object of its own.

NOTE: this is a possibly dangerous operation; do not use it unless you understand what it does. If you clone your repository using this option and then delete branches (or use any other Git command that makes any existing commit unreferenced) in the source repository, some objects may become unreferenced (or dangling). These objects may be removed by normal Git operations (such as git commit) which automatically call git maintenance run --auto. (See git-maintenance[1].) If these objects are removed and were referenced by the cloned repository, then the cloned repository will become corrupt.

Note that running git repack without the --local option in a repository cloned with --shared will copy objects from the source repository into a pack in the cloned repository, removing the disk space savings of clone --shared. It is safe, however, to run git gc, which uses the --local option by default.

If you want to break the dependency of a repository cloned with --shared on its source repository, you can simply run git repack -a to copy all objects from the source repository into a pack in the cloned repository.

If the reference <repository> is on the local machine, automatically setup .git/objects/info/alternates to obtain objects from the reference <repository>. Using an already existing repository as an alternate will require fewer objects to be copied from the repository being cloned, reducing network and local storage costs. When using the --reference-if-able, a non existing directory is skipped with a warning instead of aborting the clone.

NOTE: see the NOTE for the --shared option, and also the --dissociate option.

Borrow the objects from reference repositories specified with the --reference options only to reduce network transfer, and stop borrowing from them after a clone is made by making necessary local copies of borrowed objects. This option can also be used when cloning locally from a repository that already borrows objects from another repository—​the new repository will borrow objects from the same repository, and this option can be used to stop the borrowing.

Operate quietly. Progress is not reported to the standard error stream.

Run verbosely. Does not affect the reporting of progress status to the standard error stream.

Progress status is reported on the standard error stream by default when it is attached to a terminal, unless --quiet is specified. This flag forces progress status even if the standard error stream is not directed to a terminal.

Transmit the given string to the server when communicating using protocol version 2. The given string must not contain a NUL or LF character. The server’s handling of server options, including unknown ones, is server-specific. When multiple --server-option=<option> are given, they are all sent to the other side in the order listed on the command line. When no --server-option=<option> is given from the command line, the values of configuration variable remote.<name>.serverOption are used instead.

No checkout of HEAD is performed after the clone is complete.

Fail if the source repository is a shallow repository. The clone.rejectShallow configuration variable can be used to specify the default.

Make a bare Git repository. That is, instead of creating <directory> and placing the administrative files in <directory>/.git, make the <directory> itself the $GIT_DIR. This obviously implies the --no-checkout because there is nowhere to check out the working tree. Also the branch heads at the remote are copied directly to corresponding local branch heads, without mapping them to refs/remotes/origin/. When this option is used, neither remote-tracking branches nor the related configuration variables are created.

Employ a sparse-checkout, with only files in the toplevel directory initially being present. The git-sparse-checkout[1] command can be used to grow the working directory as needed.

Use the partial clone feature and request that the server sends a subset of reachable objects according to a given object filter. When using --filter, the supplied <filter-spec> is used for the partial clone filter. For example, --filter=blob:none will filter out all blobs (file contents) until needed by Git. Also, --filter=blob:limit=<size> will filter out all blobs of size at least <size>. For more details on filter specifications, see the --filter option in git-rev-list[1].

Also apply the partial clone filter to any submodules in the repository. Requires --filter and --recurse-submodules. This can be turned on by default by setting the clone.filterSubmodules config option.

Set up a mirror of the source repository. This implies --bare. Compared to --bare, --mirror not only maps local branches of the source to local branches of the target, it maps all refs (including remote-tracking branches, notes etc.) and sets up a refspec configuration such that all these refs are overwritten by a git remote update in the target repository.

Instead of using the remote name origin to keep track of the upstream repository, use <name>. Overrides clone.defaultRemoteName from the config.

Instead of pointing the newly created HEAD to the branch pointed to by the cloned repository’s HEAD, point to <name> branch instead. In a non-bare repository, this is the branch that will be checked out. --branch can also take tags and detaches the HEAD at that commit in the resulting repository.

Create a new repository, and fetch the history leading to the given revision <rev> (and nothing else), without making any remote-tracking branch, and without making any local branch, and detach HEAD to <rev>. The argument can be a ref name (e.g. refs/heads/main or refs/tags/v1.0) that peels down to a commit, or a hexadecimal object name. This option is incompatible with --branch and --mirror.

When given, and the repository to clone from is accessed via ssh, this specifies a non-default path for the command run on the other end.

Specify the directory from which templates will be used; (See the "TEMPLATE DIRECTORY" section of git-init[1].)

Set a configuration variable in the newly-created repository; this takes effect immediately after the repository is initialized, but before the remote history is fetched or any files checked out. The <key> is in the same format as expected by git-config[1] (e.g., core.eol=true). If multiple values are given for the same key, each value will be written to the config file. This makes it safe, for example, to add additional fetch refspecs to the origin remote.

Due to limitations of the current implementation, some configuration variables do not take effect until after the initial fetch and checkout. Configuration variables known to not take effect are: remote.<name>.mirror and remote.<name>.tagOpt. Use the corresponding --mirror and --no-tags options instead.

Create a shallow clone with a history truncated to the specified number of commits. Implies --single-branch unless --no-single-branch is given to fetch the histories near the tips of all branches. If you want to clone submodules shallowly, also pass --shallow-submodules.

Create a shallow clone with a history after the specified time.

Create a shallow clone with a history, excluding commits reachable from a specified remote branch or tag. This option can be specified multiple times.

Clone only the history leading to the tip of a single branch, either specified by the --branch option or the primary branch remote’s HEAD points at. Further fetches into the resulting repository will only update the remote-tracking branch for the branch this option was used for the initial cloning. If the HEAD at the remote did not point at any branch when --single-branch clone was made, no remote-tracking branch is created.

Control whether or not tags will be cloned. When --no-tags is given, the option will be become permanent by setting the remote.<remote>.tagOpt=--no-tags configuration. This ensures that future git pull and git fetch won’t follow any tags. Subsequent explicit tag fetches will still work (see git-fetch[1]).

By default, tags are cloned and passing --tags is thus typically a no-op, unless it cancels out a previous --no-tags.

Can be used in conjunction with --single-branch to clone and maintain a branch with no references other than a single cloned branch. This is useful e.g. to maintain minimal clones of the default branch of some repository for search indexing.

After the clone is created, initialize and clone submodules within based on the provided <pathspec>. If no =<pathspec> is provided, all submodules are initialized and cloned. This option can be given multiple times for pathspecs consisting of multiple entries. The resulting clone has submodule.active set to the provided pathspec, or "." (meaning all submodules) if no pathspec is provided.

Submodules are initialized and cloned using their default settings. This is equivalent to running git submodule update --init --recursive <pathspec> immediately after the clone is finished. This option is ignored if the cloned repository does not have a worktree/checkout (i.e. if any of --no-checkout/-n, --bare, or --mirror is given)

All submodules which are cloned will be shallow with a depth of 1.

All submodules which are cloned will use the status of the submodule’s remote-tracking branch to update the submodule, rather than the superproject’s recorded SHA-1. Equivalent to passing --remote to git submodule update.

Instead of placing the cloned repository where it is supposed to be, place the cloned repository at the specified directory, then make a filesystem-agnostic Git symbolic link to there. The result is Git repository can be separated from working tree.

Specify the given ref storage format for the repository. The valid values are:

The number of submodules fetched at the same time. Defaults to the submodule.fetchJobs option.

The (possibly remote) <repository> to clone from. See the GIT URLS section below for more information on specifying repositories.

The name of a new directory to clone into. The "humanish" part of the source repository is used if no <directory> is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git). Cloning into an existing directory is only allowed if the directory is empty.

Before fetching from the remote, fetch a bundle from the given <uri> and unbundle the data into the local repository. The refs in the bundle will be stored under the hidden refs/bundle/* namespace. This option is incompatible with --depth, --shallow-since, and --shallow-exclude.
