does s4cmd accept input from stdout?

Hi

I tried something similar, but not seem working, example

echo "my file"| s4cmd put - s3://mybucket/s4cmd-test/testfile.txt &

it still expects proper source target in this case.

It looks like s4cmd can't do it = (. Just because of this, I still use s3cmd.
