NAME

cg-clone - clone a remote repository

SYNOPSIS

cg-clone [-l] [-b] [-s] LOCATION [DESTDIR]

DESCRIPTION

This clones a remote GIT repository and checks it out locally.

Takes a parameter specifying the location of the source repository and an optional second parameter specifying the destination. If the second parameter is omitted, the basename of the source repository is used as the destination.

For detailed description of the location of the source repository format (available protocols, specifying different remote branch, etc) please see the gitm[blue]1m[][1] documentation.

OPTIONS

-b

Create only the bare repository, without a working copy attached; this is useful e.g. for public repository mirrors. gitm[blue]1m[][2] is to gitm[blue]1m[][3] as cg-clone -b is to gitm[blue]1m[][4]. (Still, if you are setting up a public or a central repository other people will push into, it might be more practical to just gitm[blue]1m[][4] it and then populate it with gitm[blue]1m[][5] from the other side.)

-l

Instead of hardlinking all the objects, set up an "alternate" record pointing at the source object database; this will cause any objects not found locally to be looked up remotely, which effectively eliminates the need to copy/hardlink the objects around. This is suitable for very fast cloning of arbitrarily big repositories, but your repository will become largely useless if the source repository disappears or gets damaged (note that it is generally BAD IDEA to prune the original repository if any repository is borrowing objects from it). The choice is yours.

--reference PATH

This does the same thing as -l but instead of borrowing the objects from the source repository, it borrows them from yet another local repository. E.g. if you have Linus' kernel repository cloned locally and now want to clone akpm's repository, you can do something like
cg-clone --reference /path/to/linus/repo git://kernel.org/akpm/repo
and it will download and keep only the objects that are really missing. Same considerations and warnings on the third-party source as in the case of -l apply. Also, you can reference only local repositories.

-s

Clone in the current directory instead of creating a new one. Specifying both -s and a destination directory makes no sense.

-h, --help

Print usage summary.

--long-help

Print user manual. The same as found in gitm[blue]1m[][2].

NOTES

If the clone has been interrupted for any reason, do not panic, calmly cd to the destination directory and run gitm[blue]1m[][6], which will in this case restart the initial clone. Chances are that you will not actually download any duplicate data. (At the time of writing this, the chances aren't for the native git protocol and ssh, but this may change in the future).

EXAMPLE USAGE

If you want to clone the Cogito repository, you can say:

 $ cg-clone http://www.kernel.org/pub/scm/cogito/cogito.git
 

and it will be cloned to the cogito subdirectory of the current directory.

To clone the next branch of the Git repository, do e.g.:

 $ cg-clone git://git.kernel.org/pub/scm/git/git.git#next
