我编写了这个小bash脚本来查找我帐户中的空桶：

#!/bin/zsh
for b in $(aws s3 ls | cut -d" " -f3)
do
  echo -n $b
  if [[ "$(aws s3api list-objects-v2 --bucket $b --max-items 1)" == "" ]]
  then
    echo " BUCKET EMPTY"
  else
    echo ""
  fi
done

我使用list-objects-v2列出了对象，最大项目数为1。如果没有项目，结果为空，我在存储桶名称旁边打印“BUCKET EMPTY”。

• 注1：您必须具有列出对象的访问权限。
• 注2：我不确定它将如何工作的版本存储桶与删除的对象（似乎是空的，但实际上包含旧版本的删除对象）

这很好用，但是没有考虑非当前版本的对象。为此，你可以使用“list-object-versions”，然后它也会查找非当前版本的对象。

！/bin/zsh for b in $（aws s3 ls|cut -d”“-f3）do echo -n $B if “$（aws s3api list-object-versions --bucket $b --max-items 1）”==“” then echo“〈----- BUCKET EMPTY”else echo“”fi done

这是我今天写的一个脚本，它不会改变任何东西，但它会给予你命令行来进行更改。

for bucketlist in  $(aws s3api list-buckets  --profile $profile  | jq --raw-output '.Buckets[].Name');
do
  echo "* $bucketlist"
  if [[ ! "$bucketlist" == *"shmr-logs" ]]; then
    listobjects=$(\
      aws s3api list-objects --bucket $bucketlist \

      --profile $profile)
#echo "==$listobjects=="
    if [[ "$listobjects" == "null" ]]; then
          echo "$bucketlist is empty"
          emptybucketlist+=("$bucketlist")
    else
      # get size
      aws s3 ls --summarize  --human-readable --recursive --profile $profile s3://$bucketlist | tail -n1

      filecount=$(echo $listobjects | jq length )
      echo "contains $filecount files"
      if [[ $filecount -lt $smallbucketsize ]]; then

      fi

      echo "contains $oldfilecount old files"

      # check if all files are old
      if [[ $filecount -eq $oldfilecount ]]; then
        echo "all the files are old"
        oldbucketlist+=("$bucketlist")

      fi
