Best way is to use lifecycle rule to delete whole bucket contents. Programmatically you can use following code (PHP) to PUT lifecycle rule.

$expiration = array('Date' => date('U', strtotime('GMT midnight')));
$result = $s3->putBucketLifecycle(array(
            'Bucket' => 'bucket-name',
            'Rules' => array(
                array(
                    'Expiration' => $expiration,
                    'ID' => 'rule-name',
                    'Prefix' => '',
                    'Status' => 'Enabled',
                ),
            ),
        ));

In above case all the objects will be deleted starting Date - "Today GMT midnight".

You can also specify Days as follows. But with Days it will wait for at least 24 hrs (1 day is minimum) to start deleting the bucket contents.

$expiration = array('Days' => 1);

This used to require a dedicated API call per key  file   but has been greatly simplified due to the introduction of Amazon S3 - Multi-Object Delete in December 2011      Amazon S3 s new Multi-Object Delete gives you the ability to   delete up to 1000 objects from an S3 bucket with a single request    See my answer to the related question delete from S3 using api php using wildcard for more on this and respective examples in PHP  the AWS SDK for PHP supports this since version 1 4 8    Most AWS client libraries have meanwhile introduced dedicated support for this functionality one way or another  e g    Python  You can achieve this with the excellent boto Python interface to AWS roughly as follows  untested  from the top of my head    import boto s3   boto connect s3   bucket   s3 get bucket  bucketname   bucketListResultSet   bucket list prefix  foo bar   result   bucket delete keys  key name for key in bucketListResultSet     Ruby  This is available since version 1 24 of the AWS SDK for Ruby and the release notes provide an example  as well   bucket   AWS  S3 new buckets  mybucket      delete a list of objects by keys  objects are deleted in batches of 1k per   request   Accepts strings  AWS  S3  S3Object  AWS  S3  ObectVersion and    hashes with  key and  version id bucket objects delete  key1    key2    key3           delete all of the objects in a bucket  optionally with a common prefix as shown  bucket objects with prefix  2009    delete all    conditional delete  loads and deletes objects in batches of 1k  only   deleting those that return true from the block bucket objects delete if  object  object key       pdf        empty the bucket and then delete the bucket  objects are deleted in batches of 1k bucket delete    Or   AWS  S3  Bucket delete  your bucket    force   gt  true

With the latest aws-cli python command line tools  to recursively delete all the files under a folder in a bucket is just   aws s3 rm --recursive s3   your bucket name foo    Or delete everything under the bucket   aws s3 rm --recursive s3   your bucket name   If what you want is to actually delete the bucket  there is one-step shortcut   aws s3 rb --force s3   your bucket name   which will remove the contents in that bucket recursively then delete the bucket   Note  the s3    protocol prefix is required for these commands to work

The voted up answer is missing a step    Per aws s3 help      Currently  there is no support for the use of UNIX style wildcards in a          command s  path  arguments    However   most  commands  have  --exclude   lt value gt   and --include   lt value gt    parameters  that  can  achieve  the          desired  result          When there are multiple          filters  the rule is the filters that appear later in the command  take          precedence  over filters that appear earlier in the command   For example  if the filter parameters passed to the command were --exclude     --include    txt  All files will be excluded from the command  except  for  files  ending          with   txt   aws s3 rm --recursive s3   bucket  --exclude     --include   folder path

You might also consider using Amazon S3 Lifecycle to create an expiration for files with the prefix foo bar1   Open the S3 browser console and click a bucket   Then click Properties and then LifeCycle   Create an expiration rule for all files with the prefix foo bar1 and set the date to 1 day since file was created   Save and all matching files will be gone within 24 hours   Just don t forget to remove the rule after you re done   No API calls  no third party libraries  apps or scripts   I just deleted several million files this way   A screenshot showing the Lifecycle Rule window  note in this shot the Prefix has been left blank  affecting all keys in the bucket
