Where did git put a clone
It would be in a folder named foo
Generally, do
git clone git://github.com/foo .
Note the .
in the end. You will get the repo in the current folder.
Or explicitly specify the folder:
git clone git://github.com/foo foo.clone
The repository should have been cloned into a directory named "foo" located in whichever directory you ran the git clone
command from.
