How to sparsely checkout only one single file from a git repository?

Question

How do I checkout just one file from a git repo?

Answer 1

If you already have a copy of the git repo, you can always checkout a version of a file using a git log to find out the hash-id (for example 3cdc61015724f9965575ba954c8cd4232c8b42e4) and then you simply type:

git checkout hash-id path-to-file

Here is an actual example:

git checkout 3cdc61015724f9965575ba954c8cd4232c8b42e4 /var/www/css/page.css
