| DESCRIPTION |
| ----------- |
| |
| Clones a repository into a newly created directory, creates |
| remote-tracking branches for each branch in the cloned repository |
| (visible using `git branch -r`), and creates and checks out an |
| initial branch that is forked from the cloned repository's |
| currently active branch. |
| |
| After the clone, a plain `git fetch` without arguments will update |
| all the remote-tracking branches, and a `git pull` without |
| arguments will in addition merge the remote master branch into the |
| current master branch, if any (this is untrue when "--single-branch" |
| is given; see below). |
| |
| This default configuration is achieved by creating references to |
| the remote branch heads under `refs/remotes/origin` and |
| by initializing `remote.origin.url` and `remote.origin.fetch` |
| configuration variables. |
| |
| |
| OPTIONS |
| ------- |
| --local:: |
| -l:: |
| 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. |
| |
| --no-hardlinks:: |
| 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. |
| |
| --shared:: |
| -s:: |
| 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 gc --auto`. (See linkgit:git-gc[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 `-l` option in a repository |
| cloned with `-s` will copy objects from the source repository into a pack |
| in the cloned repository, removing the disk space savings of `clone -s`. |
| It is safe, however, to run `git gc`, which uses the `-l` option by |
| default. |
| + |
| If you want to break the dependency of a repository cloned with `-s` 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. |
| |
| --reference <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. |
| + |
| *NOTE*: see the NOTE for the `--shared` option, and also the |
| `--dissociate` option. |
| |
| --dissociate:: |
| 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. |
| |
| --quiet:: |
| -q:: |
| Operate quietly. Progress is not reported to the standard |
| error stream. |
| |
| --verbose:: |
| -v:: |
| Run verbosely. Does not affect the reporting of progress status |
| to the standard error stream. |
| |
| --progress:: |
| Progress status is reported on the standard error stream |
| by default when it is attached to a terminal, unless -q |
| is specified. This flag forces progress status even if the |
| standard error stream is not directed to a terminal. |
| |
| --no-checkout:: |
| -n:: |
| No checkout of HEAD is performed after the clone is complete. |
| |
| --bare:: |
| 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 `-n` |
| 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. |
| |
| --mirror:: |
| 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. |
| |
| --origin <name>:: |
| -o <name>:: |
| Instead of using the remote name `origin` to keep track |
| of the upstream repository, use `<name>`. |
| |
| --branch <name>:: |
| -b <name>:: |
| 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. |
| |
| --upload-pack <upload-pack>:: |
| -u <upload-pack>:: |
| 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. |
| |
| --template=<template_directory>:: |
| Specify the directory from which templates will be used; |
| (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].) |
| |
| --config <key>=<value>:: |
| -c <key>=<value>:: |
| 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 |
| linkgit: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. |
| |
| --depth <depth>:: |
| 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`. |
| |
| --[no-]single-branch:: |
| 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. |
| |
| --recursive:: |
| --recurse-submodules:: |
| After the clone is created, initialize all submodules within, |
| using their default settings. This is equivalent to running |
| `git submodule update --init --recursive` 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) |
| |
| --[no-]shallow-submodules:: |
| All submodules which are cloned will be shallow with a depth of 1. |
| |
| --separate-git-dir=<git dir>:: |
| 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. |
| |
| -j <n>:: |
| --jobs <n>:: |
| The number of submodules fetched at the same time. |
| Defaults to the `submodule.fetchJobs` option. |
| |
| <repository>:: |
| The (possibly remote) repository to clone from. See the |
| <<URLS,URLS>> section below for more information on specifying |
| repositories. |
| |
| <directory>:: |
| 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. |
