Job Confusion

Job control with sh is quite unpleasant. I’m trying to throw together a script that allows a REPL to work with pipes as input. The following example works.

  while true
    cat pipes/i
  done | sh -xv > pipes/o 2> pipes/e

Termination, however, is a horse of a different color. Echoing exit into pipes/i presumably kills the shell, but the loop runs forever.
