Find records between two files which are not exists in one another in one
Hello all,
Would like to know how to find records between two files which are not exists in one another in one. For example: I've two files "fileA" and "fileB" and want to find record from "fileB" which does not exists in "fileA".
fileA
--------
ABCD
DEFG
GHIJ
KLMN
NOPQ
RSTU
VUWX
XYZA
fileB
--------
ZYXW
ABCD
VUVS
RQPO
NMLK
JIHG
FEDC
BAZY
KLMN
RSTU
From above, the expected result must be,
fileC
--------
ZYXW
VUTS
RQPO
NMLK
JIHG
FEDC
BAZY
Please advise how to handle such cases from command line.
Thanks,
Venkat

extract_font_range(3alleg4) Allegro manual extract_font_range(3alleg4)
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.
