This is now the default when + the source repository is specified with `/path/to/repo` + syntax, so it essentially is a no-op option. To force + copying instead of hardlinking (which may be desirable + if you are trying to make a back-up of your repository), + but still avoid the usual "git aware" transport + mechanism, `--no-hardlinks` can be used. + +--no-hardlinks:: + Optimize the cloning process from a repository on a + local filesystem by copying files under `.git/objects` + directory. + +--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. + +--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. + +--quiet:: +-q:: + Operate quietly. This flag is passed to "rsync" and + "git-fetch-pack" commands when given. + +--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 `$GIT_DIR`. This obviously implies the `-n` + because there is nowhere to check out the working tree. + Also the branch heads at the remote are copied directly + to corresponding local branch heads, without mapping + them to `refs/remotes/origin/`. When this option is + used, neither remote-tracking branches nor the related + configuration variables are created. + +--origin <name>:: +-o <name>:: + Instead of using the remote name 'origin' to keep track + of the upstream repository, use <name> instead. + +--upload-pack <upload-pack>:: +-u <upload-pack>:: + When given, and the repository to clone from is handled + by 'git-fetch-pack', '--exec=<upload-pack>' is passed to + the command to specify non-default path for the command + run on the other end. + +--template=<template_directory>:: + Specify the directory from which templates will be used; + if unset the templates are taken from the installation + defined default, typically `/usr/share/git-core/templates`. + +--depth <depth>:: + Create a 'shallow' clone with a history truncated to the + specified number of revs. A shallow repository has + number of limitations (you cannot clone or fetch from + it, nor push from nor into it), but is adequate if you + want to only look at near the tip of a large project + with a long history, and would want to send in a fixes + as patches. + +<repository>:: + The (possibly remote) repository to clone from. See the + <<URLS,URLS>> section below for more information on specifying + repositories. + +<directory>:: + The name of a new directory to clone into. The "humanish" + part of the source repository is used if no directory is + explicitly given ("repo" for "/path/to/repo.git" and "foo" + for "host.xz:foo/.git"). Cloning into an existing directory + is not allowed. + +include::urls.txt[] + +Examples +-------- + +Clone from upstream:: ++ +------------ +$ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6 +$ cd my2.6 +$ make +------------ + + +Make a local clone that borrows from the current directory, without checking things out:: ++ +------------ +$ git clone -l -s -n . ../copy +$ cd ../copy +$ git show-branch +------------ + + +Clone from upstream while borrowing from an existing local directory:: ++ +------------ +$ git clone --reference my2.6 \ + git://git.kernel.org/pub/scm/.../linux-2.7 \ + my2.7 +$ cd my2.7 +------------ + + +Create a bare repository to publish your changes to the public:: ++ +------------ +$ git clone --bare -l /home/proj/.git /pub/scm/proj.git +------------ + + +Create a repository on the kernel.org machine that borrows from Linus:: ++ +------------ +$ git clone --bare -l -s /pub/scm/.../torvalds/linux-2.6.git \ + /pub/scm/.../me/subsys-2.6.git +------------ + + +Author +------ +Written by Linus Torvalds <torvalds@osdl.org> + + +Documentation +-------------- +Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. + + +GIT +--- +Part of the gitlink:git[7] suite |
