bash script to create and switch between multiple domains to use with GAMADV-XTD3. Place in the same directory as your gam executable. (made with copilot assistance)

gaminit.sh

#!/bin/bash
# Script name: gaminit
#
# This script sets the GAMCFGDIR environment variable to the directory where the script is located,
# appended with a domain name provided as an argument. If the specified domain subdirectory does not exist,
# it prompts the user to confirm if they want the directory to be created.
#
# Does NOT WORK with standard gam, as only GAMADV-XTD3 supports the GAMCFGDIR environment variable!!
#
# If a 'gam' executable is found in the same directory as the script, it adds the directory to the PATH.
#
# Usage: source ./gaminit.sh domain
# Example: source ./gaminit.sh example.com
#
# Note: To make GAMCFGDIR available in your current shell, you must source this script instead of running it.

# Check if the script is being sourced
if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then
