Rough notes on using GAM to print all Members of all Groups in Google Workspace

Since google failed to provide helpful UI for the administrators, we used GAMADV to print all members of all groups.

GAMADV-XTD3 6.30.10 - https://github.com/taers232c/GAMADV-XTD3 - pyinstaller
Ross Scroggs <ross.scroggs@gmail.com>
Python 3.11.0 64-bit final
Linux Ubuntu 22.04 Jammy Jellyfish x86_64
Path: /home/bib/bin/gamadv-xtd3
Config File: /home/bib/.gam/gam.cfg, Section: DEFAULT, customer_id: my_customer, domain: 

To install:

bash <(curl -s -S -L https://git.io/fhZWP) -l;

To authorize:

gam user bob@bytefreaks.net check serviceaccount;

This created a link for the browser which we followed to authorize the API.
Example output:

When the box closes you're done
After authorizing it may take some time for this test to pass so wait a few moments and then try this command again.

After authorizing, we executed again to verify that all tests passed:

Finally, we executed the following to create a CSV file that contained all members of all groups:

gam print group-members > emails.2022.csv;
