This script is a wrapper around curl, a popular command line http client, that
will calculate the authentication parameters for the request.

To start, create an .s3curl file in your home directory.  This file will contain your
AWS Access Key Id and AWS Secret Access Key pairs.

For example:

%awsSecretAccessKeys = (
    # personal account
    # personal is a [friendly-name] . It can be named anything & is used in given s3curl commands.
    personal => {
        id => '1ME55KNV6SBTR7EXG0R2',
        key => 'zyMrlZUKeG9UcYpwzlPko/+Ciu0K2co0duRM3fhi',
    },

   # corporate account
   company => {
        id => '1ATXQ3HHA59CYF1CVS02',
        key => 'WQY4SrSS95pJUT95V6zWea01gBKBCL6PI0cdxeH8',
    },
);

After creating the .s3curl file, you can try the following commands using s3curl. 

To get an object, you would run:

./s3curl.pl --id=[friendly-name] -- http://s3.amazonaws.com/[bucket-name]/[key-name]

If you just want to see the object's metadata, run:

./s3curl.pl --id=[friendly=name] --head -- http://s3.amazonaws.com/[bucket-name]/[key-name]

[Note]
Install perl-Digest-HMAC.noarch package , if you got an error while running s3curl commands starting with the below phrase.  
"Can't locate Digest/HMAC_SHA1.pm in @INC"

The arguments after the '--' are passed through to curl, so you could put any
curl specific options there, and then the url you are trying to get.

To put an object, run:

./s3curl.pl --id=[friendly-name] --put=<file-name> -- http://s3.amazonaws.com/[bucket-name]/[key-name]

To delete an object:

./s3curl.pl --id=[friendly-name] --delete -- http://s3.amazonaws.com/[bucket-name]/[key-name]

To copy an object:

./s3curl.pl --id=[friendly-name] --copy=[source-bucket-name/source-key-name] -- http://s3.amazonaws.com/[bucket-name]/[key-name]

To restore an object (previously archived to Glacier):

./s3curl.pl --id=[friendly-name] --post --data-binary "<RestoreRequest><Days>[number-of-days]</Days></RestoreRequest>" -- http://s3.amazonaws.com/[bucket-name]/[key-name]?restore

To list a bucket:

./s3curl.pl --id=[friendly-name] -- http://s3.amazonaws.com/[bucket-name]

To create a bucket:

./s3curl.pl --id=[friendly-name] --createBucket -- http://s3.amazonaws.com/[bucket-name]

To create a bucket with a location constraint EU:

./s3curl.pl --id=[friendly-name] --createBucket=EU -- http://s3.amazonaws.com/[bucket-name]

To delete a bucket:

./s3curl.pl --id=[friendly-name] --delete -- http://s3.amazonaws.com/[bucket-name]

To enable versioning for a bucket:

./s3curl.pl --id=[friendly-name] --put ~/versioningEnable -- http://s3.amazonaws.com/[bucket-name]?versioning

where, contents of ~/versioningEnable is

<?xml version="1.0" encoding="UTF-8"?>
<VersioningConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <Status>Enabled</Status>
</VersioningConfiguration>

Doing a GET for an object on a bucket where versioning is enabled, returns the latest version. 

./s3curl.pl --id=[friendly-name] -- http://s3.amazonaws.com/[bucket-name]/[key-name] -v

[Look for x-amz-version-id in the response]

To get a specific version of an object:

./s3curl.pl --id=[friendly-name] -- http://s3.amazonaws.com/[bucket-name]/[key-name]?versionId=[version-id]

To get a ACL for a specific version of an object:

./s3curl.pl --id=[friendly-name] -- http://s3.amazonaws.com/[bucket-name]/[key-name]?versionId=[version-id]&acl

To copy a specific version of an object:

./s3curl.pl --id=[friendly-name] --copy=[source-bucket-name/source-key-name?versionId=[version-id]] -- http://s3.amazonaws.com/[bucket-name]/[key-name]

To list all the versions in a bucket:

./s3curl.pl --id=[friendly-name] -- http://s3.amazonaws.com/[bucket-name]?versions


SECURITY CONSIDERATION:

On a shared system, it is dangerous to specify your AWS Secret Access Key on
the command line, as any other user on the machine can view your command line.
Therefore we strongly advocate the use of .s3curl file to store and manage your
keys.
