Using CURL to Upload Files via POST to Amazon S3

A few months ago I wrote a post about creating Amazon S3 HMAC Signatures without PEAR or PHP5. One of the things I was using that PHP script for was to feed the necessary information to a bash script hosted on a remote machine. The bash script was to upload a file via POST to Amazon S3 using the information provided.

Since CURL was already installed on the remote machine, I wanted to use that to do the actual uploading. I found very little help on the net regarding how to do this with CURL so here you go:

eris:~ raam$ curl
-F "key=screenshots/current_screenshot.jpg"
-F "acl=public-read"
-F "AWSAccessKeyId=2EO6H8MX1X8YWEA0V432"
-F "Policy=eyAiZXhwaXshdGlvbpI6ICIyMDA4LTErLTAxVDtyOjAwOjAwLjAsMFoiLAogICJjb25kaXRpb25zPjogWwoJeyJidWNrZXQiOiAiczNwaG90b3MubW9hcHAubmV0IiB9LAogICAgWyJzdGFydHMtd2l0aCIsICIka2V5IiwgIkxpdmVTaG90cy8iXSwKICAgIHsiYWNsIjogInB1YmxpYy1yZWFkIiB9LAoJWyJlcSIsICIkQ29udGVudC1UeXBlIiwgImltYWdlL2pwZWciXSwKICBdCn0K"
-F "Signature=20uh08kU75ADHL49NyhYRgZW8BY="
-F "Content-Type=image/jpeg"
-F "file=@current_screenshot.jpg"

Keep in mind this assumes the current_screenshot.jpg file is in your current directory.
