I was unable to get Nanoix's perl script to work, or other curl examples I had seen, so I started looking into the api myself in python. This worked fine for small files, but large files choked past available ram so I found some other nice chunking code that uses the api's ability to partial download. Gist here:
https://gist.github.com/csik/c4c90987224150e4a0b2
Note the bit about downloading client_secret json file from the API interface to your local directory.
Source$ cat gdrive_dl.py
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
"""API calls to download a very large google drive file. The drive API only allows downloading to ram
(unlike, say, the Requests library's streaming option) so the files has to be partially downloaded
and chunked. Authentication requires a google api key, and a local download of client_secrets.json
