# This script initiates restoration requests for Glacier objects listed in a specified file,
# but only if they haven't been restored yet, do not have an ongoing restoration request,
# and are still in the Glacier storage class. The script processes these objects in parallel
# using xargs to speed up the execution.
# It requires the bucket name, file name, and the number of days for the restoration.
# Example usage:
# ./restore-glacier-objects.sh my-bucket object-list.txt 3
# (Initiates restoration for objects listed in 'object-list.txt' in 'my-bucket' for 3 days)
# Check the number of arguments
if [[ $# -ne 3 ]]; then
echo "Usage: $0 <bucket_name> <file_name> <number_of_days>"
