panyam - We do not really need much more information then what he provided. Create test data and mess with it.

Priya - You can use sed, which is probably a bit easier. You have to use the -n otherwise it will send output twice. You can see a lot of info on sed at the following pages:
Famous Sed One-Liners Explained, Part I - good coders code, great reuse
Sed - UNIX Stream Editor - Cheat Sheet - good coders code, great reuse
http://www.oracle.com/technology/pub...laney_sed.html

Here is a solution for your issue below (followed by an issue you may have)
Code:
-bash-3.2$ cat test.txt
One
Two
Three
Four
Five
Orange
Red
Blue
Black
Yellow
Silver
-bash-3.2$ sed -n '/Four/,/Black/ p' test.txt
Four
Five
Orange
Red
Blue
Black
-bash-3.2$ sed -n '/Four/,/Black/ p' test.txt | wc -l
6

If you have two sets of matches, for instance, going with the above example, you had another 'Four'/'Black' further down the file. It will return both groups, not between the groups, but just the groups themselves.. for instance:

Code:
-bash-3.2$ cat test.txt
One
Two
Three
Four
Five
Orange
Red
Blue
Black
Yellow
Silver
Four
Hundred
Black
-bash-3.2$ sed -n '/Four/,/Black/ p' test.txt
Four
Five
Orange
Red
Blue
Black
Four
Hundred
Black
-bash-3.2$ sed -n '/Four/,/Black/ p' test.txt | wc -l

Which may be confusing, but it is correct. Hope this helps!

desktop_palette

desktop_palette(3alleg4)					  Allegro manual					  desktop_palette(3alleg4)

NAME

       desktop_palette - The palette used by the Atari ST low resolution desktop. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       extern PALETTE desktop_palette;

DESCRIPTION

       The  palette  used by the Atari ST low resolution desktop. I'm not quite sure why this is still here, except that the grabber and test pro-
       grams use it. It is probably the only Atari legacy code left in Allegro, and it would be a shame to remove it :-)

       The contents of this palette are 16 colors repeated 16 times. Color entry zero is equal to color entry 16, which is equal  to  color  entry
       24, etc.

	  Index      Color	 RGB values
	    0	  White 	 63  63  63
	    1	  Red		 63   0   0
	    2	  Green 	  0  63   0
	    3	  Yellow	 63  63   0
	    4	  Blue		  0   0  63
	    5	  Pink		 63   0  63
	    6	  Cyan		  0  63  63
	    7	  Grey		 16  16  16
	    8	  Light grey	 31  31  31
	    9	  Light red	 63  31  31
	   10	  Light green	 31  63  31
	   11	  Light yellow	 63  63  31
	   12	  Light blue	 31  31  63
	   13	  Light pink	 63  31  63
	   14	  Light cyan	 31  63  63
	   15	  Black 	  0   0   0
