Delete all versions of all files in s3 versioned bucket using AWS CLI and jq.

delete_all_object_versions.sh

#!/bin/bash

bucket=$1

set -e

echo "Removing all versions from $bucket"

versions=`aws s3api list-object-versions --bucket $bucket |jq '.Versions'`
markers=`aws s3api list-object-versions --bucket $bucket |jq '.DeleteMarkers'`
let count=`echo $versions |jq 'length'`-1

if [ $count -gt -1 ]; then
        echo "removing files"
        for i in $(seq 0 $count); do
                key=`echo $versions | jq .[$i].Key |sed -e 's/\"//g'`
                versionId=`echo $versions | jq .[$i].VersionId |sed -e 's/\"//g'`

Apparently base64 gets into the mix if versions / deletemarkers become too numerous?

#!/bin/bash

bucket=$1

set -e

echo "Removing all versions from $bucket"

versions=`aws s3api list-object-versions --bucket $bucket |jq '.Versions'`
markers=`aws s3api list-object-versions --bucket $bucket |jq '.DeleteMarkers'`

echo "removing files"
for version in $(echo "${versions}" | jq -r '.[] | @base64'); do 
    version=$(echo ${version} | base64 --decode)

    key=`echo $version | jq -r .Key`
    versionId=`echo $version | jq -r .VersionId `
    cmd="aws s3api delete-object --bucket $bucket --key $key --version-id $versionId"
    echo $cmd
    $cmd
done

echo "removing delete markers"
for marker in $(echo "${markers}" | jq -r '.[] | @base64'); do 
    marker=$(echo ${marker} | base64 --decode)

    key=`echo $marker | jq -r .Key`
    versionId=`echo $marker | jq -r .VersionId `
    cmd="aws s3api delete-object --bucket $bucket --key $key --version-id $versionId"
    echo $cmd
    $cmd
done
