Just for fun (and because I ~like~ jot)

Call the original file test

#!/bin/sh
Y="$(wc -l test)"
jot -s "$Y" < test

Kevin's solution is more elegant (and more robust I think).

It proves the adage that in Unix (and of course, Unix-like systems)
there's always more than one way to do something.  (The corollary is
that somone will think your way is stupid.)  :)
