Simple challenge - Cyanide and Cynicism - 09-13-2013
Credits to Tarball for challenge, thought this was cool.
--
Unix master Myong was told of a stray cat that had taken up residence in the operations hall, sleeping in the server cabinets and napping atop the ancient CRTs for warmth. The situation had grown objectionable when the creature began using a crate of spare cables as a litterbox.
Myong captured the cat and placed it on a table before six monks of the Clan of Iron Bones, saying, “If each of you can speak a command line which performs the same function as cat, I will spare this animal. If not, I will kill it.”
The first monk quickly said, “cat”.
The second said, “grep ^”.
The third said, “sed s/^//”.
The fourth said, “tr x x <”.
The fifth said, “perl -pe 0”.
You are the sixth.
Rules:
- Must print it to terminal
- Must be able to run in Bash shell, utilities like tcl and awk are allowed but no other shells like cshell or fish
- No invoking text editors like nano or vi, unless it prints directly to terminal
- Can't use a solution posted before

You still have a chance to reclaim yourself though, we have an entire kitten mill to kill until someone gets it right.

Code:
deadkitty='cat' && $deadkittyJust so nobody else can use it.

There's still plenty of other solutions OniOni, people just have to figure them out.

By the way, killing cats is now a bannable offense.
Spoiler:
Kidding.

You aren't supposed to directly invoke cat by name, for an example of an acceptable use of it look at Oni's.
RE: Simple challenge - w00t - 09-13-2013
Yet the first monk used "cat".
When I've time I'll make a quick script to use head to do it.

That's because it was in the original story :p. This is a challenge modified from an old Unix koan.
