I've got several large files sitting in my linux hosted account that I need to upload to my S3 account. I dont want to download them first and then upload it into S3.

Is there any way I can "upload" it via the linux command line environment? Or access it via a website working with lynx?

http://s3tools.org/s3cmd does what you want to. Uploading & downloading files, syncing directories and creating buckets.

Amazon provides their own CLI tools now too.

From http://aws.amazon.com/cli/

Using familiar syntax, you can view the contents of your S3 buckets in a directory-based listing.

$ aws s3 ls s3://mybucket
      LastWriteTime     Length Name
      -------------     ------ ----
                           PRE myfolder/
2013-09-03 10:00:00       1234 myfile.txt

You can perform recursive uploads and downloads of multiple files in a single folder-level command. The AWS CLI will run these transfers in parallel for increased performance.

$ aws s3 cp myfolder s3://mybucket/myfolder --recursive
upload: myfolder/file1.txt to s3://mybucket/myfolder/file1.txt
upload: myfolder/subfolder/file1.txt to s3://mybucket/myfolder/subfolder/file1.txt

A sync command makes it easy to synchronize the contents of a local folder with a copy in an S3 bucket.

$ aws s3 sync myfolder s3://mybucket/myfolder --exclude *.tmp
upload: myfolder/newfile.txt to s3://mybucket/myfolder/newfile.txt

Documentation for file related commands is here.

If you can't (perhaps you're on a shared host) or don't want to install extra tools, it is possible to just use bash, curl, and openssl.


dateValue=`date -R`
signature=`echo -en ${stringToSign} | openssl sha1 -hmac ${s3Secret} -binary | base64`
curl -L -X PUT -T "${file}" \
  -H "Host: ${bucket}.s3.amazonaws.com" \
  -H "Date: ${dateValue}" \
  -H "Content-Type: ${contentType}" \
  -H "Authorization: AWS ${s3Key}:${signature}" \

Note that I modified this script from the one in the above link. I added the -L option because AWS may insert a redirect in there. The -L option will follow the redirect for you.

One other caveat. This won't work for files larger than 5GB. Those require a multi-part upload that would require a more complex script.
