Calling shell commands?

This may be a very naive question, but is there any simple way to call
an external shell command from VW running on Linux or MacOsX? I looked
in the Unix- and Mac- subclasses of ExternalInterface but there does
not seem to be any such facility.
All I am trying to do is to launch an external program (GnuPlot) to
work on a VW-generated data file.

Cheers,

Stefano

Naive questions are welcome here :-)

See the class side of UnixProcess.
For example inspect the result of:

  UnixProcess shOne: 'ls -l'
