    AWS S3 Bucket bulk deletion

To utilize the AWS CLI for listing S3 buckets and deleting those that match a specific pattern, follow these steps. This guide focuses on how to remove buckets starting with the prefix "sk."
Requirements

AWS CLI must be installed.
Appropriate AWS credentials and permissions should be set up.

Step 1: Get a List of Buckets
First, use the AWS CLI installed on your machine to retrieve a list of all S3 buckets.
aws s3 ls
Step 2: Delete Buckets Matching a Specific Pattern
To delete buckets beginning with "sk," you can use a shell script to filter out and remove these buckets.
The script below identifies bucket names starting with "sk" and proceeds to delete each one. Note: This script will remove the bucket and all its contents. Ensure you have backed up your data beforehand.
aws s3 ls | awk '{print $3}' | grep '^sk' | while read bucket
do
    echo "Deleting bucket $bucket..."
    aws s3 rb s3://$bucket --force
done
Script Functions:

aws s3 ls: Lists all buckets.
awk '{print $3}': Extracts only the bucket names.
grep '^sk': Filters for bucket names starting with "sk."
while read bucket; do ... done: Deletes each matched bucket in a loop.

Caution

Ensure you have backed up any necessary data before proceeding with deletion.
Use the --force option in aws s3 rb to remove a bucket and all its contents if it's not empty.
It is advisable to insert an echo statement before executing the delete command to confirm the names of the buckets being deleted.
