"""
# Purpose: For a Google Drive User(s), show all drive file ACLs for Team Drive files shared with selected groups.
# Note: This script requires Advanced GAM with Team Drive support:
# https://github.com/taers232c/GAMADV-XTD, https://github.com/taers232c/GAMADV-XTD3
# Customize: Set FILE_NAME and ALT_FILE_NAME based on your environment. Set GROUP_LIST.
# Usage:
# For all Team Drives, start at step 1; For Team Drives selected by user/group/OU, start at step 6
# All Team Drives
# 1: Get all Team Drives.
# $ gam redirect csv ./TeamDrives.csv print teamdrives fields id,name
# 2: Get ACLs for all Team Drives
# $ gam redirect csv ./TeamDriveACLs.csv multiprocess csv TeamDrives.csv gam print drivefileacls ~id
# 3: Customize GetTeamDriveOrganizers.py for this task:
# Set DOMAIN_LIST as required
# Set ONE_ORGANIZER = True
# Set SHOW_GROUP_ORGANIZERS = False
# Set SHOW_USER_ORGANIZERS = True
# 4: From that list of ACLs, output a CSV file with headers "id,name,organizers"
# that shows the organizers for each Team Drive
# $ python GetTeamDriveOrganizers.py TeamDriveACLs.csv TeamDrives.csv TeamDriveOrganizers.csv
# 4: Get ACLs for all team drive files
# $ gam redirect csv ./filelistperms.csv multiprocess csv TeamDriveOrganizers.csv gam user ~organizers print filelist select teamdriveid ~id fields teamdriveid,id,title,permissions
# 5: Go to step 10
# Selected Team Drives
# 6: If 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
# 7: Customize DeleteDuplicateRows.py for this task:
# Set ID_FIELD = 'id'
# 8: Delete duplicate Team Drives (some may have multiple organizers).
# $ python DeleteDuplicateRows.py ./AllTeamDrives.csv ./TeamDrives.csv
# 9: Get ACLs for all team drive files
# $ gam redirect csv ./filelistperms.csv multiprocess csv TeamDrives.csv gam user ~User print filelist select teamdriveid ~id fields teamdriveid,id,title,permissions
# Common code
# 10: From that list of ACLs, output a CSV file with headers "Owner,driveFileId,driveFileTitle,permissionId,role,emailAddress"
# that lists the driveFileIds and permissionIds for all ACLs with the desired groups
# (n.b., driveFileTitle, role, and emailAddress are not used in the next step, they are included for documentation purposes)
# $ python GetSharedWithGroupTeamDriveACLs.py filelistperms.csv deleteperms.csv
# 11: Inspect deleteperms.csv, verify that it makes sense and then proceed
# 12: Delete the ACLs
# $ gam csv deleteperms.csv gam user "~Owner" delete drivefileacl "~driveFileId" "~permissionId"
