[ aws . s3 ]



List S3 objects and common prefixes under a prefix or all S3 buckets. Note that the --output and --no-paginate arguments are ignored for this command.


<S3Uri> or NONE
[--page-size <value>]
[--request-payer <value>]


paths (string)

--recursive (boolean) Command is performed on all files or objects under the specified directory or prefix.

--page-size (integer) The number of results to return in each response to a list operation. The default value is 1000 (the maximum allowed). Using a lower value may help if an operation times out.

--human-readable (boolean) Displays file sizes in human readable format.

--summarize (boolean) Displays summary information (number of objects, total size).

--request-payer (string) Confirms that the requester knows that she or he will be charged for the request. Bucket owners need not specify this parameter in their requests. Documentation on downloading objects from requester pays buckets can be found at


The following ls command lists all of the bucket owned by the user. In this example, the user owns the buckets mybucket and mybucket2. The timestamp is the date the bucket was created, shown in your machine's time zone. Note if s3:// is used for the path argument <S3Uri>, it will list all of the buckets as well:

aws s3 ls


2013-07-11 17:08:50 mybucket
2013-07-24 14:55:44 mybucket2

The following ls command lists objects and common prefixes under a specified bucket and prefix. In this example, the user owns the bucket mybucket with the objects test.txt and somePrefix/test.txt. The LastWriteTime and Length are arbitrary. Note that since the ls command has no interaction with the local filesystem, the s3:// URI scheme is not required to resolve ambiguity and may be omitted:

aws s3 ls s3://mybucket


                           PRE somePrefix/
2013-07-25 17:06:27         88 test.txt

The following ls command lists objects and common prefixes under a specified bucket and prefix. However, there are no objects nor common prefixes under the specified bucket and prefix:

aws s3 ls s3://mybucket/noExistPrefix



The following ls command will recursively list objects in a bucket. Rather than showing PRE dirname/ in the output, all the content in a bucket will be listed in order:

aws s3 ls s3://mybucket --recursive

The following ls command demonstrates the same command using the --human-readable and --summarize options. --human-readable displays file size in Bytes/MiB/KiB/GiB/TiB/PiB/EiB. --summarize displays the total number of objects and total size at the end of the result listing:

aws s3 ls s3://mybucket --recursive --human-readable --summarize
