For loop to break apart word
Code:
notimes=5
word=excellency

the word excellency contains 10 letters. 10 letters divided by 2 = 5. which means, 5 two-groups of letters are in the word excellency.

i need to perform a function on each group of letters. but the only thing i can think of is the following, which i just know isn't efficient:

Code:
while [ $notimes -le 5 ] ; 
do
lum1=$(echo $word | cut -c1-2)
lum2=$(echo $word | cut -c3-4)
lum3=$(echo $word | cut -c5-6)
lum4=$(echo $word | cut -c7-8)
lum5=$(echo $word | cut -c9-10)
mycommand lum1 lum2 ......
 
done

in the above scenario, we know the word (excellency). but in the scenario this script will work on, the words will be unknown. but the number of characters in whatever the word is will always be divided by 2.

in the above while loop scenario, i knew the number of characters in the word, because i knew the word, so i hardcoded the "cut" command to break it apart. but that wont be case when this script is put to work.

how can i automate the while loop? awk?

boggle

BOGGLE(6)							   Games Manual 							 BOGGLE(6)

NAME

       boggle - play the game of boggle

SYNOPSIS

       /usr/games/boggle [ + ] [ ++ ]

DESCRIPTION

       This  program  is  intended for people wishing to sharpen their skills at Boggle (TM Parker Bros.).  If you invoke the program with 4 argu-
       ments of 4 letters each, (e.g.  "boggle appl epie moth erhd") the program forms the obvious Boggle  grid  and  lists  all  the  words  from
       /usr/dict/words	found  therein.  If  you invoke the program without arguments, it will generate a board for you, let you enter words for 3
       minutes, and then tell you how well you did relative to /usr/dict/words.

       The object of Boggle is to find, within 3 minutes, as many words as possible in a 4 by 4 grid of letters. Words	may  be  formed  from  any
       sequence  of 3 or more adjacent letters in the grid. The letters may join horizontally, vertically, or diagonally.  However, no position in
       the grid may be used more than once within any one word. In competitive play amongst humans, each player is given credit for those  of  his
       words which no other player has found.

       In  interactive play, enter your words separated by spaces, tabs, or newlines. A bell will ring when there is 2:00, 1:00, 0:10, 0:02, 0:01,
       and 0:00 time left. You may complete any word started before the expiration of time. You  can  surrender  before  time  is  up  by  hitting
       'break'. While entering words, your erase character is only effective within the current word and your line kill character is ignored.

       Advanced  players  may wish to invoke the program with 1 or 2 +'s as the first argument. The first + removes the restriction that positions
       can only be used once in each word. The second + causes a position to be considered adjacent to itself as well as its (up to) 8 neighbors.
