S3 Simple Storage Service
Usage
The following is S3cmd usage (as shown if you type s3cmd -h). To access all the options and commands listed below, you'll need s3cmd version 2.0 or newer
Usage: s3cmd [options] COMMAND [parameters]
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.
Options:
-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
them all.
-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.
--access_key=ACCESS_KEY
AWS Access Key
--secret_key=SECRET_KEY
AWS Secret Key
--access_token=ACCESS_TOKEN
AWS Access Token
-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.
(default)
--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
[get] command).
--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.
--upload-id=UPLOAD_ID
UploadId for Multipart Upload, in case you want
continue an existing upload (equivalent to --continue-
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
for [get] and [sync] commands).
-r, --recursive Recursive upload, download or removal.
--check-md5 Check MD5 sums when comparing files for [sync].
(default)
--no-check-md5 Do not check MD5 sums when comparing files for [sync].
Only size will be compared. May significantly speed up
transfer but may also miss some changed files.
-P, --acl-public Store objects with ACL allowing read for anyone.
--acl-private Store objects with default ACL allowing access for you
only.
--acl-grant=PERMISSION:EMAIL or USER_CANONICAL_ID
Grant stated permission to a given amazon user.

write_acp, full_control, all
--acl-revoke=PERMISSION:USER_CANONICAL_ID

Permission is one of: read, write, read_acp, wr
ite_acp, full_control, all
