[ aws . s3 ]

ls

Description

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.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  ls
<S3Uri> or NONE
[--recursive]
[--page-size <value>]
[--human-readable]
[--summarize]
[--request-payer <value>]

Options

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 they 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 http://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html

See ‘aws help’ for descriptions of global parameters.

Examples

Example 1: Listing all user owned buckets

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. This date can change when making changes to your bucket, such as editing its bucket policy. Note if s3:// is used for the path argument <S3Uri>, it will list all of the buckets as well:

aws s3 ls

Output:

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

Example 2: Listing all prefixes and objects in a bucket

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

Output:

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

Example 3: Listing all prefixes and objects in a specific bucket and prefix

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

Output:

None

Example 4: Recursively listing all prefixes and objects in a bucket

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

Output:

2013-09-02 21:37:53         10 a.txt
2013-09-02 21:37:53    2863288 foo.zip
2013-09-02 21:32:57         23 foo/bar/.baz/a
2013-09-02 21:32:58         41 foo/bar/.baz/b
2013-09-02 21:32:57        281 foo/bar/.baz/c
2013-09-02 21:32:57         73 foo/bar/.baz/d
2013-09-02 21:32:57        452 foo/bar/.baz/e
2013-09-02 21:32:57        896 foo/bar/.baz/hooks/bar
2013-09-02 21:32:57        189 foo/bar/.baz/hooks/foo
2013-09-02 21:32:57        398 z.txt

Example 5: Summarizing all prefixes and objects in a bucket

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

Output:

2013-09-02 21:37:53   10 Bytes a.txt
2013-09-02 21:37:53  2.9 MiB foo.zip
2013-09-02 21:32:57   23 Bytes foo/bar/.baz/a
2013-09-02 21:32:58   41 Bytes foo/bar/.baz/b
2013-09-02 21:32:57  281 Bytes foo/bar/.baz/c
2013-09-02 21:32:57   73 Bytes foo/bar/.baz/d
2013-09-02 21:32:57  452 Bytes foo/bar/.baz/e
2013-09-02 21:32:57  896 Bytes foo/bar/.baz/hooks/bar
2013-09-02 21:32:57  189 Bytes foo/bar/.baz/hooks/foo
2013-09-02 21:32:57  398 Bytes z.txt

Total Objects: 10
   Total Size: 2.9 MiB

Example 6: Listing from an S3 access point

The following ls command list objects from access point (myaccesspoint):

aws s3 ls s3://arn:aws:s3:us-west-2:123456789012:accesspoint/myaccesspoint/

Output:

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