How do I determine the total size of a directory (folder) from the command line?

The command du “summarizes disk usage of each FILE, recursively for directories,” e.g.,

du -hs /path/to/directory

How to find the path of the local git repository when I am possibly in a sub-directory?

git rev-parse --show-toplevel

How do I remove a folder?

Be sure the folder is really empty (hidden files/folders might be in there). Look at the file contents again with

sudo ls -lha /path/

If you’re absolutely certain that it doesn’t contain anything you want to have (including subdirectories), delete it with

sudo rm -r -f /path/

The -r makes it delete the folder (and subfolders), even if it is non-empty, -f is for force (this might be unnecessary).
