If you are running under unix, MIT Scheme has (system "...") as a
primitive procedure. In order to use it you should do something like:

  (define system (make-primitive-procedure 'system))
  (system "...")

The following is the documentation string for "system":

  "Invoke sh (the Bourne shell) on the string argument.\n\
  Wait until the shell terminates, returning its exit status as an
  integer."
