To find words that have at least one double but not more than 3:
The number can be parameterized with a shell variable.

Hey Alister!
I don't really know sed very well, but let me see if I can figure this out. I think it's worth pointing out that I have no background with this stuff. I'm just learning on my own, in my spare time, such as it is.
In the first regex, it looks like you're finding any instance of doubles, then saying do not delete, presumably so the pattern gets passed to the second regex?
In the second regex, it looks like you're saying substitute "nothing" with the found pattern. I'm guessing the "4" is a quantifier? And the "t'"? I have no idea.
I feel I have a vague notion of what you're doing, but can't entirely parse the two regexes. But, here we are with two (three?) regexes again. Is it really not possible to do this in a single grep ERE, or PCRE?
hey there,

to determine if two two doubles are equal, we check to see if
their absolute difference is very close to zero. . .if two numbers
are less than .00001 apart, theyre equal.
keep a count field in each record (as you did in p5).
once the list is complete, ask the user to see if an element

Hi!
I have concatenated two files which are wordlists, i.e., one word per line. The new file contains some doubles, but I cannot use sort and uniq as I need to keep the sort order that it is already in, which is not alphabetical, and uniq only compares adjacent lines, and the doubles are not on...

BOGGLE(6) BSD Games Manual BOGGLE(6)NAME
boggle -- word search game
SYNOPSIS
boggle [-bd] [-s seed] [-t time] [-w length] [+ [+]] [boardspec]
DESCRIPTION
The object of boggle is to find as many words as possible on the Boggle board within the three minute time limit. A Boggle board is a four
by four arrangement of Boggle cubes, each side of each cube displaying a letter of the alphabet or `qu'. Words are formed by finding a
sequence of cubes (letters) that are in the game's dictionary. The (N+1)th cube in the word must be horizontally, vertically, or diagonally
adjacent to the Nth cube. Cubes cannot be reused. Words consist solely of lower case letters and must be at least 3 letters long.
Command line flags can be given to change the rules of the game.
-b Run boggle in batch mode. A boardspec must also be given. The dictionary is read from stdin and a list of words appearing in
boardspec is printed to stdout.
-d Enable debugging output.
-s seed Specify a seed seed other than the time of day.
-t time Set the time limit for each game from the default 3 minutes to time seconds.
-w length Change the minimum word length from 3 letters to length.
+ This flag allows a cube to be used multiple times, but not in succession.
++ This flag allows the same cubes to be considered adjacent to itself.
boardspec A starting board position can be specified on the command line by listing the board left to right and top to bottom.
Help is available during play by typing '?'. More detailed information on the game is given there.
BUGS
If there are a great many words in the cube the final display of the words may scroll off of the screen. (On a 25 line screen about 130
words can be displayed.)
No word can contain a 'q' that is not immediately followed by a 'u'.
When using the + or ++ options the display of words found in the board doesn't indicate reused cubes.
