GetTeamDriveCountsSize.py

#!/usr/bin/env python3
"""
# Purpose: Get file counts/total size for Team Drives
# Note: This script requires Advanced GAM:
#	https://github.com/taers232c/GAMADV-XTD3
# Python: Use python or python3 below as appropriate to your system; verify that you have version 3
#  $ python -V   or   python3 -V
#  Python 3.x.y
# Usage:
# 1: If you want to include all Team Drives, do this step and then skip to step 4, otherwise start at step 2.
#  $ gam redirect csv ./TeamDrives.csv print teamdrives fields id,name
# 2: If you want Team Drives for a specific set of organizers, replace <UserTypeEntity> with your user selection in the command below
#  $ gam redirect csv ./AllTeamDrives.csv <UserTypeEntity> print teamdrives role organizer fields id,name
# 3: Delete duplicate Team Drives (some may have multiple organizers). Make sure that ID_FIELD = 'id' in DeleteDuplicateRows.py
#  $ python3 DeleteDuplicateRows.py ./AllTeamDrives.csv ./TeamDrives.csv
# 4: Get ACLs for all Team Drives
#  $ gam redirect csv ./TeamDriveACLs.csv multiprocess csv ./TeamDrives.csv gam print drivefileacls "~id" fields emailaddress,role,type
# 5: From that list of ACLs, output a CSV file with headers "id,name,organizers"
#    that shows the organizers for each Team Drive
# 6: Customize GetTeamDriveOrganizers.py
#    Set DOMAIN_LIST as desired
#    Set ONE_ORGANIZER = True
#    Set SHOW_GROUP_ORGANIZERS = False
#    Set SHOW_USER_ORGANIZERS = True
#  $ python3 GetTeamDriveOrganizers.py TeamDriveACLs.csv TeamDrives.csv TeamDriveOrganizers.csv
# 7: Get Team Drive files
#  $ gam config csv_input_row_filter "organizers:regex:^.+$" redirect csv ./TeamDriveFiles.csv multiprocess csv ./TeamDriveOrganizers.csv gam user "~organizers" print filelist select teamdriveid "~id" fields id,name,driveid,size
# 8: Get Team Drive counts/size info
#  $ python3 GetTeamDriveCountsSize.py TeamDriveFiles.csv TeamDrives.csv TeamDriveCountsSize.csv
