[LUNA] simple(ton?) bash question ....

[Paul F. Pearson]

(1) Consider some of the bash and bourne shell tutorials. 

(2) when declaring functions in bash/sh, you use empty parens. Also, the keyword 'function' is a bash-ism -- not wrong, but IMO it doesn't add much.

(3) You likely should consider using quotes as a habit, to help avoid corner cases (sadly, some file names contain whitespace).

Here's my take on what you're trying to acheive (hasn't been tested, so beware...). 

$ lltr10 () { lltr "$*" | tail -10 }
$ export lltr10

or 

$ function lltr10 () { lltr "$*" | tail -10 }
$ export lltr10
