# This script lists all objects in a specified AWS S3 bucket that were moved to the GLACIER storage class within a specified number of days ago.
# Usage: ./show_obgects_moved_to_glacier.sh your-bucket-name aws-profile days_ago
# Get the arguments
bucket="$1"
profile="$2"
days_ago="$3"

# Set the page size for pagination
page_size=100

# Initialize a counter for the number of objects
count=0

# Initialize a counter for the number of objects processed

# Calculate the date days_ago days ago in Unix timestamp in UTC

  # Debug: Print the key, last modified date, and storage class of the object for debugging
  # echo "Key: $key, Last Modified: $last_modified, Storage Class: $storage_class"

Script: show_objects_moved_to_glacier.sh

This script lists all objects in a specified AWS S3 bucket that were moved to the GLACIER storage class within a specified number of days ago.

Usage

./show_objects_moved_to_glacier.sh <your-bucket-name> <aws-profile> <days_ago>

Parameters

• <your-bucket-name>: The name of the AWS S3 bucket to check.
• <aws-profile>: The AWS profile to use for AWS CLI commands.
• <days_ago>: The number of days ago to check for objects moved to GLACIER.

How it works

1. The script first initializes some variables based on the command line arguments, including the bucket name, AWS profile, and number of days ago to check.
2. It calculates the date <days_ago> days ago in Unix timestamp in UTC.
3. The script then lists all objects in the specified bucket that have a storage class of GLACIER.
4. For each object, it extracts the key and the LastModified date.
5. The LastModified date is converted to a Unix timestamp.
6. The script then checks if the LastModified date is greater than or equal to the date <days_ago> days ago. If it is, the script increments a counter.
7. Finally, the script prints the total number of objects that were moved to GLACIER within the specified number of days ago.
