After a long search I discovered what seems to be the best practices solution for users that need to transfer files between Linux and Google Drive:
The CLI version is very recent and its documentation, unclear.
The URL for Google Storage is of the form:
gs://[container]/[key]
My Google Drive account is the basic, freebie. I have looked around but don't know how to determine my [container] and [key].
TIA.
Addition:
I have found that that "[container]" is the same as a "bucket". However, the "[key]" remains as a mystery.
