What I gave above is the output i want.

The input is like this:
Code:
       Key1              Key2              Key3       102                 30                   0       102   40   1       102   50   2       103   12   0       103   15   1

I need to add three new columns to the existing columns above and insert data into them from the column Key2.

The output is expected to look like this:
Code:
         Key1   Key2   Key3   New_Key1   New_Key2   New_Key3       102   30   0   -   -   -       102   40   1   30   40   50       102   50   2   40   50   30       103   12   0   -   -   -       103   15   1   12   15   12

The first row to any unique Key1, has New_Key1, New_Key2, New_Key3 dashed out. Now for the next row, the first value of Key2(in this case 30) becomes New Key1, the second value of Key2(40) fills in for New_Key2 and the third value(50) fills in for New_Key3. The process then repeats for the next row where the 2nd, 3rd and 4th values of Key2 are taken to fill New_Key1, New_Key2 and New_Key3 repectively. All this happens provided its mapped to the same Key1. I hope I'm clearer now.

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
