Given sufficient s3cmd setup, this script can be used to paste stuff into your bucket.

pastie

#! /bin/bash -e

BUCKET="mabucket"
PASTE="paste"

if [ $# -eq 0 ]; then echo "Usage: $0 filename, or -l for list"; exit 1;fi
if [ $1 = "-l" ]; then s3cmd ls s3://$BUCKET/$PASTE/; exit 0; fi

FILENAME=`date +"%s"`
cp $1 /tmp/$FILENAME.txt

s3cmd put -P /tmp/$FILENAME.txt s3://$BUCKET/$PASTE/$FILENAME >/dev/null 2>/dev/null

echo "File $1 pasted to http://$BUCKET/$PASTE/$FILENAME"
