The following is S3cmd usage (as shown if you type s3cmd -h). To access all the options and commands listed below, you'll need version 1.6 or newer
S3cmd is a tool for managing objects in Amazon S3 storage. It allows for
making and removing "buckets" and uploading, downloading and removing
"objects" from these buckets.
-h, --help show this help message and exit
--configure Invoke interactive (re)configuration tool. Optionally
use as '--configure s3://some-bucket' to test access
to a specific bucket instead of attempting to list
-c FILE, --config=FILE
Config file name. Defaults to $HOME/.s3cfg
--dump-config Dump current configuration after parsing config files
and command line options and exit.
AWS Access Key
AWS Secret Key
-n, --dry-run Only show what should be uploaded or downloaded but
don't actually do it. May still perform S3 requests to
get bucket listings and other information though (only
for file transfer commands)
-s, --ssl Use HTTPS connection when communicating with S3.
--no-ssl Don't use HTTPS.
-e, --encrypt Encrypt files before uploading to S3.
--no-encrypt Don't encrypt files.
-f, --force Force overwrite and other dangerous operations.
--continue Continue getting a partially downloaded file (only for
--continue-put Continue uploading partially uploaded files or
multipart upload parts. Restarts/parts files that
don't have matching size and md5. Skips files/parts
that do. Note: md5sum checks are not always
sufficient to check (part) file equality. Enable this
at your own risk.
UploadId for Multipart Upload, in case you want
continue an existing upload (equivalent to
put) and there are multiple partial uploads. Use
s3cmd multipart [URI] to see what UploadIds are
associated with the given URI.
--skip-existing Skip over files that exist at the destination (only

-r, --recursive Recursive upload, download or removal.
--check-md5 Check MD5 sums when comparing files for [sync].

instead of GLOB
