It should be simpler than the way you have it....
all that "|" means is give the write end to stdout of the left hand process and the read end to stdin for the right hand process.
but apart from > and <, the stdin/stdout/stderr should just be left alone.
To do ">" you just open a file and use it for stdout, end of story.
I personally would parse the line into a tree where each node is what I want to run in one process, each node would have pointers to where they get their stdin/stdout/stderr from.

DEAL(6) Games Manual DEAL(6)
NAME
deal - bridge hand generator
SYNOPSIS
deal [ -ltv ] [ -e expr ] [ -i condition file ] [ -I format ] [ -s seed ] [ -[NSEW] hand-spec ] [ count ]
DESCRIPTION
deal is a program to generate bridge hands.
OPTIONS
-l Write deals in a "single-line" format.
-t Print distribution table and exit. The distribution table is an ordered list of all possible hand patterns for a single hand.
-v Be verbose, print sample count.
-e expr
Evaluate the Tcl expression expr.
-i condition file
File that defines the hand type to generate or the output format. (Can be given multiple times.)
-I format
Read hands from stdin. Formats available are: ddline, giblib, line, pbn, smartstack. You might deal, say, 10,000 hands which sat-
isfy specific criteria, saving them to a file. Then you can use that output for input with deal -I to find out which hands satisfy
other constraints.
-s seed
Initialize random generator with seed.
-[NSEW] hand-spec
Specifies the cards held by the specified hand. The hand-spec should be of the form: "AK8532 - KQ72 A65". Voids must be represented
with a '-' character. hand-spec should be one argument, so the string should be quoted on the command line.
count Number of hands to generate, default is 10.
