The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

While I agree you can do that w/o cat this example really is a minor nit IMHO. A better example of UUOC would be those situations where you "cat file|awk" or "cat file|sed" where you can "awk file" or "sed -i file".
Looks like you've got a solution already, but I thought I'd mention the fmt command, which is aimed at text formatting - unfortunately (at least on HP-UX!) it doesn't have an option to fill/join lines to an arbitrary width. But it's occasionally useful to fill lines to a certain width... in particular, in vi typing !}fmt will line-fill the current paragraph, which is very handy when entering a lot of text.
"xargs < file" is the nicest one-liner I've seen in a long time :-)
