Print a list of aws buckets along with their tags

aws-s3-buckets-with-tags.sh

#!/bin/bash
# lists all buckets along with their tags in the following format:
# bucket_name | { tag_name: tag_value }
# depends on AWS CLI and JQ

for bucket in `aws s3api list-buckets | jq .Buckets[].Name | tr -d \"`; do 
    tags=$(aws s3api get-bucket-tagging --bucket $bucket | jq -c '.[][] | {(.Key): .Value}' | tr '\n' '\t')
    echo $bucket '|' $tags
done

update the above line and it will give you clear output
echo $bucket '|' $tags >> buckets-tags.txt

I know this is old.. But you don't need jq for the bucket list step. Also added some additional stuff to answer other questions.

for bucket in `aws s3api list-buckets --query "Buckets[].Name" --output text` ; do
    echo $bucket
    tags=$(aws s3api get-bucket-tagging --bucket $bucket 2>/dev/null| jq -cr '.[][] | {(.Key): .Value}')
    output=${tags:-"no Tags assigned"}
    echo $output
done
