# This script is designed to manage and clean up old directories and files within the ./downloads folder.
# Its primary purpose is to delete directories and their contents that are older than 1 week (168 hours) to free up disk space
# and maintain a clean file system. This script will iterate through all the files in the ./downloads folder
# and delete all sub-folders and files if the folder was created more than 1 week ago. If there are files in this folder,
# the files will also be deleted one by one.

# Define path to the downloads directory
download_folder="./downloads/"
# cutoffMins = 1 week ago = 168 hours ago (in seconds)
cutoffMins=$((169 * 60)) # add 1 hour to handle edge case, which is job finished at 1:00 am.

# Traverse the download folder and remove directories older than cutoff time
# -mindepth 1: Excludes the top-level directory, includes only subdirectories
