# ==============================================================================
# USAGE INSTRUCTIONS & DOCUMENTATION
# ==============================================================================
# Purpose: Automatically mounts a remote SMB share and downloads specified 
#          directories to a local destination using rsync with deep auditing.
#
# How to use:
# 1. Update the CONFIGURATION section below with your desired paths and SMB server details.
# 2. In the 'paths' array, you can copy-paste either Windows or Mac paths.
#    ⚠️ IMPORTANT: If a path contains backslashes (\) or spaces, you MUST enclose 
#       it in SINGLE QUOTES ('...') to prevent Bash from misinterpreting them.
# 3. Make the script executable: chmod +x download_smb.sh
# 4. Run the script: ./download_smb.sh
# ==============================================================================

# ==========================================
# CONFIGURATION & INFORMATION SECTION
# ==========================================
# 1. Local destination directory on your Mac
DEST_BASE="/Users/common/Meetings"

# 2. SMB Server connection details
SMB_SERVER="windows.plusmagi.com"
SMB_BASE="commmon_technical"

# 3. List of target directories to download (Supports both Windows and Mac paths)
paths=(
	'importData',
    'event,
	'HolidayCalendar'
	'VDO Training\Day 1'
	'VDO Training\Day 2'
