Reinventing a square wheel

Wes Groleau

OK, this has probably already been done a hundred times,
but I wanted to get some practice. But I'm doing something
wrong and I can't see it.

File "PickOne" is:

#!/usr/bin/perl

@words = <STDIN>;

$new_word = $words[rand(@words)];

chomp ($new_word);

print ($new_word);


shell command

ls | PickOne

has no output. If I use `ls` instead of stdin,
it does give me one filename each time.
