Helper file for for Google Workspace (GSuite) Resellers using GAMADV-XTD3 and need to swap between resold customers regularly

gamselect.sh

#!/bin/bash

# 
#
# Author: Duncan Isaksen-Loxton
# Web: sixfive.com.au 
#

# PREREQUISITES

# Must have GAMADV-XTDV3 installed https://github.com/taers232c/GAMADV-XTD3 
# We group all our GAM related files in a folder called GAMConfig 
# We leave GAM to install to its default location e.g. $HOME/bin/gamadv-xtd3/gam 
# 

# INSTALLATION

# Create a folder and add place this script in it e.g. 
# 
# mkdir ~/GAMConfig 
# curl -s -S -L https://gist.githubusercontent.com/65/b5e9cee9b5812b487b8ae3e8256e262b/raw/4d4c1faef49d2d0e3036452b44e3f5a5156bdb93/gamselect.sh > ~/GAMConfig/gamselect.sh && chmod +x ./GAMConfig/gamselect.sh

# Customise the ROOTPATH as required
# When used this will create a folder below this with each domain to sort generated CSV into folders

# Edit your ~/.profile or or ~/.bashrc or ~/.zshrc and add the line:
# source ~/GAMConfig/gamselect.sh
#
# echo 'source ~/GAMConfig/gamselect.sh' >> ~/.zshrc
#
# Restart your terminal 

# GAMADV-XTDV3 Config 

# When you start your gam config you will need to point it to the GAMConfig directory 
# gam config config_dir ~/GAMConfig verify


# USAGE

# from your command line 
# gamselect domainame.com
#


function gamselect(){


  # Set the path to the GAM you want to use
  GAM=$HOME/bin/gamadv-xtd3/gam

  # Path to the folder for your GAM CSV output
  # We use a  folder called GAMoutput with a folder for each domain below
  ROOTPATH="$HOME/GAMOutput/"

  # Mostly won't change 
  FILE=$HOME/GAMConfig/gam.cfg

  # May need to change when Google change API output
