Both the linux 386 and amd64 versions crash. I downloaded the binaries from your release section @ https://github.com/surma/s3put/releases

Sorry for taking so long to address this, I was quite swamped. I’m investigating now.

Okay, so it’s not a bug per se, it’s just that I didn‘t handle malformed bucket URLs gracefully.

I fixed it in 3.0.3 (commit 4b8bc5d) and updated the README. I’m uploading new binaries as well.

Please take a look and try again. Closing this for now, but feel free to re-open if the problem persists :)
