How to display only files from aws s3 ls command

Question

I am using the AWS CLI to list the files in an s3 bucket using the following command (documentation):

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

This command gives me the following 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

However, this is my desired output:

a.txt foo.zip foo/bar/.baz/a foo/bar/.baz/b foo/bar/.baz/c foo/bar/.baz/d foo/bar/.baz/e foo/bar/.baz/hooks/bar foo/bar/.baz/hooks/foo z.txt

How can I omit the date, time and file size in order to show only the file list?
