I am showing here the How to guide for amazon-simpledb-cli(Command Line Interface)
This tool depends on the following Perl modules from CPAN:

      Getopt::Long     Pod::Usage     Digest::SHA1     Digest::HMAC     XML::Simple
You can install them using the "cpan" command on your distro:

sudo cpan Getopt::Long
sudo cpan Pod::Usage
sudo cpan Digest::SHA1
sudo cpan Digest::HMAC
sudo cpan XML::Simple

This tool also depends on the Amazon::SDB modules provided by Amazon(not the one in CPAN). Amazon's modules can be found here:

http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1136

Here is the How to for the above:
curl -Lo amazon-simpledb-perl-library.zip \       http://amazon-simpledb-perl-library.notlong.com
unzip amazon-simpledb-perl-library.zip
sitelib=$(perl -MConfig -le 'print $Config{sitelib}')
sudo scp -r amazon-simpledb-*-perl-library/src/Amazon $sitelib

Finally, this command line interface can be installed with:

     sudo curl -Lo /usr/local/bin/simpledb http://simpledb-cli.notlong.com     sudo chmod +x /usr/local/bin/simpledb

Now to test your installation::
  1. Extract the amazon-simpledb-2007-11-07-perl-library.zip file into a working directory.
  2. Edit desired sample. For example: src/Amazon/SimpleDB/Samples/CreateDomainSample.pl
    • Set AWS Access Key ID and AWS Secret Access Key
    • my $AWS_ACCESS_KEY_ID = “”;my $AWS_SECRET_ACCESS_KEY = “”;
    • Set request parameters. For example, find following pre-generated snippet:
      • use Amazon::SimpleDB::Model::CreateDomain;
# @TODO: set action. Action can be passed as
Amazon::SimpleDB::Model::CreateDomain
# object or hash of parameters
# invokeCreateDomain($service, $action);
    • And set action with DomainName parameter:
      • use Amazon::SimpleDB::Model::CreateDomain;
my $action = Amazon::SimpleDB::Model::CreateDomain->new;
invokeCreateDomain($service, $action->withDomainName("MyDomain"));
  3. Run CreateDomain sample:
    4.    perl src/Amazon/SimpleDB/Samples/CreateDomainSample.pl
  4. You should see the output similar to the following:
    5. CreateDomainResponse       ResponseMetadata           RequestId               95cdcb68-f46c-400b-8265-8c2de2a5c475
  5. Experiment with samples. When ready, install library in the perl include path and use it.
