"""
# Purpose: For a Google Drive User(s), show all drive file ACLs for files shared with a list of users from a CSV file
# Note: This script can use GAM7 or Advanced GAM:
# https://github.com/GAM-team/GAM
# https://github.com/taers232c/GAMADV-XTD3
# Customize: Set USER_HEADERS
# 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: Prepare a CSV file with a list of user email addresses; set USER_HEADERS to identify the column(s) containing the email addresses
# $ more Users.csv
# email
# ...
# $ more QuadUsers.csv
# email1,email2,email3,email4
# ...
# 2: Get ACLs for all files, if you don't want all users, replace all users with your user selection in the command below
# If you don't want all files, use query/fullquery
# $ gam config auto_batch_min 1 redirect csv ./filelistperms.csv multiprocess all users print filelist fields id,title,permissions,owners.emailaddress,mimetype pm type user notrole owner em pmfilter
# 3: From that list of ACLs, output a CSV file with headers "Owner,driveFileId,driveFileTitle,mimeType,permissionId,role,emailAddress"
# that lists the driveFileIds and permissionIds for all ACLs with the desired users
# (n.b., driveFileTitle, mimeType, role, and emailAddress are not used in the next step, they are included for documentation purposes)
# $ python3 GetSharedWithListOfUsersDriveACLs.py filelistperms.csv deleteperms.csv Users.csv
# 4: Inspect deleteperms.csv, verify that it makes sense and then proceed
# 5: If desired, delete the ACLs
# $ gam csv ./deleteperms.csv gam user "~Owner" delete drivefileacl "~driveFileId" "~permissionId"
