CLI/sh: Delete AWS Buckets starting with the specified string (including versioned and non-empty)

delete-buckets.md

Delete all buckets whose name starts with the string parameter. Works on versioning buckets and buckets containing objects.

# Delete all buckets whose name starts with the string parameter. Works on versioning buckets and buckets containing objects.
# Usage:
#       deleteBucket "bucketname"        Deletes buckets whose name starts with 'bucketname'
deleteBucket()
{
  BUCKETS=`aws s3api list-buckets --output text --query "Buckets[?starts_with(Name, '$1')].Name"`
  IFS=$'\t'
  for BUCKET in $BUCKETS; do :
    echo starting to remove bucket $BUCKET
    aws s3api delete-objects --bucket $BUCKET --delete \
          "$(aws s3api list-object-versions --bucket $BUCKET --query='{Objects: Versions[].{Key:Key,VersionId:VersionId}}')"
    aws s3api delete-objects --bucket $BUCKET --delete \
          "$(aws s3api list-object-versions --bucket $BUCKET --query='{Objects: DeleteMarkers[].{Key:Key,VersionId:VersionId}}')"
    aws s3 rb s3://$BUCKET --force
    aws s3api list-buckets --query "Buckets[?starts_with(Name, '$BUCKET')].Name"
  done
  unset IFS
}

There might be enhancements around suppressing noise or deleting old buckets with spaces in their names, maybe.
