stdinxout1
Cross-connect two programs' stdin and stdout
Usage
stdinxout prog1
[args1..]
--
prog2
[args2..]
Overview
stdinxout runs the programs prog1 and prog2 with their respective arguments and connects prog1's standard output into prog2's standard input, and vice versa. Both prog1 and prog2 standard error outputs go to the standard error of stdinxout.
Restrictions
Neither prog1 or any of args1 can be exactly the characters "--", as this is used for separating the programs.
