# btpguid - return BTP subaccount/directory GUIDs

# Usage: btpguid [-t|--target] displayname

# Returns the GUID for the given subaccount or directory, which is
# specified by name. If the option -t or --target is specified, it
# will also set that subaccount or directory as the target.

  # Requires the btp CLI. Will direct you to log in first if you're
  # not already logged in.

  # It uses the detail from the output of this command:
  # btp get accounts/global-account --show-hierarchy

# Uses the "${2:-$1}" technique seen in fff - see
# https://qmacro.org/autodidactics/2021/09/03/exploring-fff-part-1-main/
# for details.
