Git only checkout certain directories

Question

How can I setup my git project to only clone/checkout certain directories.

In my project I have the following directories

/dira
/dirb
/dirc

In some cases I would only like to checkout dira , in some cases I would only like to checkout dirb , and in some cases I would only like to checkout dirc . There are also times I would want to checkout all 3 directories.

Answer 1

Its pretty simple but you cant configure git to do automatically:

# Checkout any desired file or path
git checkout <commit id> -- /path/to/dir

Note

The 2 -- at the end are important and cannot be left off.
