You wonder about these people that don't read threads, then followup with
the stupidest suggestions.

Oh, come come. A C program? tsk tsk, since we're talking about tty
security, we have to use a real hacker's tool -- perl:


#! /usr/princeton/bin/perl

require "ioctl.pl";

@s = split(//, "cd /me/A/B/C/D\n");

for (0..$#s) { ioctl(STDOUT, $TIOCSTI, $s[$_]); }
