Find size of checked-out code in current directory

Question

I want to find the size of the current checked-out files in a folder/project, but ignore the git directory.

Something like:

du . --ignore '.git'

Is there a way to find the size of all the files ignoring what's in the .git folder? When I do this:

du . --exclude='.git'   
du . --exclude='./.git'  # or this

Either way, I get:

du: --exclude=./.git: No such file or directory

What do I do?

Answer 1

For whatever reason (likely the BSD history of the Mac's utilities), the macOS version of du does not include --exclude. However, at least as of 10.14.x, it does include the much-less-obviously-named -I option which ignores items that are in the "mask" that is provided--in this case "mask" is just another name for some form of regular expression which at least takes simple * and ? wildcards.

Running

 du -I .git .

gives the size heirarchy, and

 du -s -I .git .

gives the summary. In both cases, the .git directory is ignored.
