Thanks. Replacing nawk by awk worked perfectly.
Now my other question is:

In the example you have stated, we get all the possible set of combinations of 3 letter string from 'abcd'.
But if I replace 'abcd' with 'abc_d' then I get set of string which have '_' underscore as well. However, I want that whatever be the parent string (including '_"), the generated abbreviation should not have an underscore.

How do I eliminate the occurrence of underscore.

Also, I understood the functions that you have created but what does the following line do:

Code:
awk -v Abbrev_Len=${2:-6}

Can you please provide me a link where I can get information about awk and how to use it in UNIX scripts?

Thank you very much!

CURSES_UNDERSCORE(3)					   BSD Library Functions Manual 				      CURSES_UNDERSCORE(3)

NAME

     curses_underscore, underscore, underend, wunderscore, wunderend -- curses underscore attribute manipulation routines

LIBRARY

     Curses Library (libcurses, -lcurses)

SYNOPSIS

     #include <curses.h>

     int
     underscore(void);

     int
     underend(void);

     int
     wunderscore(void);

     int
     wunderend(void);

DESCRIPTION

     These functions manipulate the underscore attribute on stdscr or on the specified window.

     The underscore() function turns on the underscore attribute on stdscr.  The underend() function turns off the underscore attribute on stdscr.

     The wunderscore() and wunderend() functions are equivalent to underscore() and underend(), respectively, excepting that the attribute is
     manipulated on the window specified by win.

     The underscore() and underend() functions are equivalent to wattron(A_UNDERLINE) and wattroff(A_UNDERLINE), respectively.

RETURN VALUES

     These functions always return 1.

SEE ALSO

     curses_attributes(3), curses_standout(3)

STANDARDS

     The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification.

HISTORY

     These functions first appeared in NetBSD 1.5.
