gdoc-util
gdoc-util is a personal command-line tool by Chat Wacharamanotham for creating Google Docs in a chosen Google Drive folder and for changing a Doc’s link sharing (private, anyone with the link can view, anyone with the link can comment), including an automatic check that the change took effect.
It runs only on the developer’s own computer and is not a hosted service. It is not distributed to the public and has no sign-up.
