Put file from `stdin`

[A1EF]

Is it possible to read file from stdin with put? Since s3cmd supports that I tried something like that with s4cmd but got error:

~$ echo foo | s4cmd --endpoint-url https://s3.example.net put - s3://bucketname/test
[OSError] 2: No such file or directory
[Thread Failure] [Errno 2] No such file or directory: '-'
