[S3tools-general] How to use the sign command s3cmd sign STRINGTOSIGN?

[Ken R. <kre...@ya...>]

This is the text in Amazon Simple Storage Service Developer Guide
Authenticating REST Requests for the first example.

Example Object GET
This example gets an object from the johnsmith bucket.

REQUEST
GET /photos/puppy.jpg HTTP/1.1 
Host: johnsmith.s3.amazonaws.com 
Date: Tue, 27 Mar 2007 19:36:42 
+0000 
Authorization: AWS 0PN5J17HBG

STRINGTOSIGN
GET\n
\n
\n
Tue, 27 Mar 2007 19:36:42 +0000\n
/johnsmith/photos/puppy.jpg


I have tried entering STRINGTOSIGN (by pasting) text with or without \n and quoted text with \n, but the signature comes out wrong. 

How do I specify STRINGTOSIGN in the command?
