Hereafetr is an example which "connects" a shell to the interpreter using pipes

(define p (run-process "/bin/sh" :input :pipe :output :pipe))
(define in (process-input p))
(define out (process-output p))
(format in "ls -ls \n")
(flush in) ;; Important otherwise buffering will not send the line (should
              ; be changed)
(read-line out)
===> first line of the ls command

Hope it helps
