I think for helping new people it's better to provide the best answer
only and leave it at that, rather than provide a not-so-good answer
first and then say "maybe it would be better to do XYZ"... :)

The other example in this email is also a UUOC:

> cat "file" | split -b 500M

can be more efficiently written:

  split -b 500M < "file"

In general, cat can almost always be avoided giving a more efficient
(sometimes GREATLY more efficient depending on the situation, other
times just a little bit more efficient) result.
