title: Is it possible to create "fake" file like unix socket and which allows write with `echo`?
body: <p>Is is possible (in Ruby or in general) to create some kind of blackhole file like socket. But to allow write as to regular file <code>echo "newline" &gt;&gt; my-fake-file</code>.</p>
  
  <p>I tried unix socket, but it fails to write into it. I don't care about reading it, because all  would be processed by running daemon. Best would be not to write into it at all.</p>
  
  <p>Why I need it? I need to process logs written to file. And nginx allows only file logs (without patch).</p>
