The command is definately going to save your day if you have disowned the process by mistake. Only uses strace so might as well work on Solaris also, though not tried it.

  <td>
    <div class="text codecolorer">
      strace -e write=1,2 -p $PID 2>&1 | sed -un "/^ |/p" | sed -ue "s/^.{9 }(.{50}).+/1/g" -e 's/ //g' | xxd -r -p
    </div>
  </td>
</tr>

Useful to recover a output(stdout and stderr) “disown”ed or “nohup“ep process of other instance of ssh.
