what is the format that you have for the credit card number and are the below format available:

meaning is it possible that exist 2 spaces only ?
Code:
11111111 1111 9621

because I have wrote a script that applicable with 3 spaces and no spaces format only.

I mean is the first space after the first 4 digits exist or not?

Note:- there is no problem if there are no spaces.

---------- Post updated at 15:30 ---------- Previous update was at 15:02 ----------

kindly note that the position that you mentioned earlier are not the 11 && 12 fields but they are the 12 && 13 fields

use below
use nawk , gawk or /usr/xpg4/bin/awk



Code:
nawk '
($12 ~ /TXE|AF|XT|TT|IT|TX|DX|TY|DT|MO|SE|CF|AXE|DF|CX|TF|DE|XF|CNE|IX|CN|SC|XTE|AX|CX/)
{
m=match($13," ")
x=length($13)
             if (m) {
                         s=substr($13,1,7)
                         b=substr($13,x-3)
                        for (i=8;i<x-3;i++) {stars=stars"*"}
                     }
             else {
                          s=substr($13,1,6)
                          b=substr($13,x-3)
                          for (i=7;i<x-3;i++) { stars=stars"*" }
                    }
    $13= s stars b
}
1' FS=":" OFS=":" infile.txt > outfile.txt

then you can rename the output file:-
mv outfile.txt  infile.txt

for the VDI pattern just change the above mention fields to the required one
and feed us back about the program above.

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
