Assignment 6 - teh leet filter

Due date: Thursday, 11/2, 2:30pm

Write a shell script, ~/bin/leet, that filters normal English and produces the equivalent [Leet]. The script should be able to act on lines of standard input.

Sample:

$ fortune

Beauty is truth, truth beauty, that is all
Ye know on earth, and all ye need to know.
                -- John Keats

$ fortune | leet

Use the "standard" character substitutions (apply to both upper and lower case):

O → 0
P → p
Q → q
R → r
S → 5
T → 7

Also apply the following word substitutions:

are → r

beginner → noob
best → leetest
better → leeter
boxer → boxor
dude → dood
good → leet
hacker → haxor
joy → woot
kill → frag

rock → roxor
rule → roolz
software → warez
the → teh
you → u

... And these miscellaneous substitutions:

ee → ea
. →    (periods, commas and apostrophes just disappear)

Apply word and miscellaneous substitutions first, and then letter substitutions.
