4. Create a local
master
branch that will point to the same revision as the
origin/master
remote tracking branch:
$ git rev-parse
origin/master > .git/refs/heads/master
5. Set up the
master
branch as a local tracking branch for the remote
tracking branch
origin/master
with:
$ git branch --set-
upstream-to=origin/master
6. Store the information about the default branch in the remote repository
locally:
$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/master
7. Checkout the files in the working directory:
$ git checkout
How It Works
This recipe demystifies the cloning operation. It splits cloning into:
• Initialization
• Definition of a remote
• Downloading the git database and remote tracking branches
• Creating appropriate branches
Git starts a clone, initializing a new empty repository with the
$ git init
com-
mand. Right after this command the repository is empty—it doesn't contain any
branches. The output of
$ git branch
is empty.
To copy the revisions from an external source we need an URL. This URL is set
with the
$ remote add [alias] [URL]
command. The first parameter is the
short alias; the second parameter is an URL. Once you define a remote
origin
with:
$ git remote add origin
https://github.com/creationix/
you can use a short alias
origin
instead of full URL. The command:
$ git fetch --no-tags origin master:refs/remotes/origin/
master
