I am running Google Drive File Stream Version: 25.252.289.1612 on OS X 10.12.6 which mounts/Volumes/GoogleDrive/
Open a Bash shell (I use iTerm3). When I ls (or ls -a) this directory, I get no results. But if I use tab completion, I can see the two subdirectories, 'My Drive' and 'Team Drive' as well as some other stuff. As I cd into subdirectories, again ls shows no files but tab completion shows them. And I can operate on files/directories. So if there is a file foo.gsheets , I can open * open foo.gsheets* which will launch in Chrome, for example. Or if I had foo.txt I could vi foo.txt. I checked that I had read/write/execute permission on files and dirs. And even tried to sudo ls .
Any ideas? Here is my mount drivefs on /Volumes/GoogleDrive (dfsfuse_DFS, local, nodev, nosuid, synchronous, mounted by aberezin)
