Use the less command to view the words file.
To see the results of a grep that returns many rows, pipe the output of the grep into less. For example, grep ‘the' words | less

You can pipe the output of a grep command into wc -l to count lines instead of displaying them.
How many words in this file begin with the letter x?
How many words in this file begin with the letter z?
How many words in this file begin with the letter x or z?

find or count the words in dictionary that:
end in ing (such as counting)
include ing but not at the end (such as ringing)
begin with a capital letter
contain only two letters, the first is lower case, the second uppercase (such as kW)
contain only the letters in simon in any order (such as osmosis)
begin with a vowel (aeiou)
do not contain a vowel (such as rhythm)
contain four consecutive vowels (such as queue)
are there any words with 5 consecutive vowels?
can be spelled using the 7 hex letters (such as faced)
contain all five vowels in the correct order a,e,i,o,u




2. Relevant commands, code, scripts, algorithms:
grep, less,pipes,egrep

LEARN ABOUT NETBSD

boggle

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.

     The dictionary that NetBSD installs omits many words that belong in the English language, most notably inflected forms.
