# Switch Account Language Script
#
# This script automates the process of switching an account to a new language.
# It deletes the Chrome profile cache and re-authenticates to get a fresh profile
# with the new language settings from Google Account.
#
# PREREQUISITE: You must first change the language in Google Account settings:
# https://myaccount.google.com/language
#
# Usage:
# ./switch-account-language.sh --account=rom1pey --lang=en
# ./switch-account-language.sh --account=mathieu --lang=fr
# ./switch-account-language.sh --account=rpmonster --lang=en --show
set -e
# Default values
