Deepen an existing shallow clone with git

By admin | January 31, 2012

In git, the new revolutionary DVCS system, to shallow clone a repository means to check out only the latest snapshot of a git repository, unlike a normal clone which pulls the entire repository. A shallow git repository can save bandwidth and take up less space.

git clone --depth=1 git://repo.example.com/mycoolapp

However, let’s say that once you checkout the project, compile it and decide that you want to contribute to it, then a shallow clone would probably not suffice. In this case, one can deepen the repository by using the following command inside the git repository, where n = number of revisions to deepen to:

git fetch --depth=n origin master

Saves more than having to re-clone everything from scratch and lose your working tree.
