Though you could certainly code up a bubble/insertion/quick sort
or such, how 'bout 


	#!/usr/bin/perl -w

	use IPC::Open2;
	use strict;

	my @array1 = qw(e c g h z r t a i h j l p b d r q x v a);

	open2(*R, *W, "sort") or die "Can't run sort!":
	print W join "\n", @array1;
	close W;
	chomp(@array2 = <R>);

	print "Sorted version: @array2";


After all, TMTOWTDI.
