Previously i got my GnuPG ready in Mac. Now i need to setup the s3cmd.
Mac – GnuPG Installation

For Mac:
1. Download the s3cmd package @ S3 tools – Download
 

2. Extract the archive

• tar zxf s3cmd-1.0.1.tar.gz

 

3. Move to the extracted folder and run the following command to configure the s3cmd

• ./s3cmd –configure

 

4. You will need to enter the following information

• S3 Access Key
• S3 Secret Key
• Encryption password
• Path to GPG program

 

5. You could check the path of the gpg command by

• which gpg

In my case, the path is /usr/local/bin/gpg
 

6. Save the setting if everything works fine.

Success. Your access key and secret key worked fine :-)

Now verifying that encryption works...
Success. Encryption and decryption worked fine :-)

Save settings? [y/N] y
Configuration saved to '/Users/kit/.s3cfg'

 

That’s all. For Debian Linux like Ubuntu, you can install it by apt-get install s3cmd. The gpg path would probably be /usr/bin/gpg.

Apart from the s3cmd, there is another S3 command line tool called Bucket Explorer as suggested by Kirti. You can try that too. =)

Done =)
