      Description

      A DESCRIPTION OF THE REQUEST :
      In Java 9, there will be a new API to create a pipeline of processes: https://bugs.openjdk.java.net/browse/JDK-8132394

      I would like Nashorn to provide direct support for this.



      JUSTIFICATION :
      Pipelines are very common in shell scripts. Having direct support for them in Nashorn, would greatly increase its suitability for such scripts. Moreover, Java 9 provides ProcessBuilder support for this, so the Nashorn implementation can build on this API.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      I propose the following:
      $PIPE("ls -l", "grep key", "less")

      There should also be a way to provide input to a pipe. However, a different name will need to be used for this, to avoid ambiguity (i.e. is the last argument part of the pipeline, or the input?).
