Examples

from aws-cli, each command read by CmdID

Example 1: To list all user owned buckets

The following ls example lists all of the buckets owned by the user. In this example, the user owns the buckets amzn-s3-demo-bucket and amzn-s3-demo-bucket2. 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 lsIdentify

Its output

2013-07-11 17:08:50 amzn-s3-demo-bucket
2013-07-24 14:55:44 amzn-s3-demo-bucket2

Example 2: To list all prefixes and objects in a bucket

The following ls example lists objects and common prefixes under a specified bucket and prefix. In this example, the user owns the bucket amzn-s3-demo-bucket 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://amzn-s3-demo-bucketIdentify

Its output

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

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

The following ls example 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://amzn-s3-demo-bucket/noExistPrefixIdentify

Its output

None

Example 4: To recursively list all prefixes and objects in a bucket

The following ls example recursively lists 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://amzn-s3-demo-bucket --recursiveIdentify

--recursiveCommand is performed on all files or objects under the specified directory or prefix.

Its 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: To summarize all prefixes and objects in a bucket

The following ls example runs the same command as the previous example with 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://amzn-s3-demo-bucket --recursive --human-readable --summarizeIdentify

--recursiveCommand is performed on all files or objects under the specified directory or prefix.

--human-readableDisplays file sizes in human readable format.

--summarizeDisplays summary information (number of objects, total size).

Its 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: To list objects in an S3 access point

The following ls example lists objects from access point (myaccesspoint).

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

Its output

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