Thanks Guru..

this is what i did to the script :
Code:
echo "Enter filename that you want to modify"
read destfile
nawk 'NR==FNR{a[$1]=i++;next}{print $1, (a[$1])?a[$1]:$2}' FS=," " OFS=," " i=240000 source.txt $destfile > tempfile
mv -f tempfile $destfile


My source file is :
Code:
edited, confidential datafile

Actually my destination file (original) was looking like this :
Code:
edited, confidential datafile

After running the script above, I'm getting this:
Code:
edited, confidential datafile

Which is correct when changing the fields values, but how do I get rid of the "," behind
Code:
edited, confidential datafile

etc?

load_datafile_object

load_datafile_object(3alleg4)					  Allegro manual				     load_datafile_object(3alleg4)

NAME

       load_datafile_object - Loads a specific object from a datafile. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       DATAFILE *load_datafile_object(const char *filename, const char *objectname);

DESCRIPTION

       Loads  a specific object from a datafile. This won't work if you strip the object names from the file, and it will be very slow if you save
       the file with global compression. Example:

	  /* Load only the music from the datafile. */
	  music_object = load_datafile_object("datafile.dat",
					      "MUSIC");
	  /* Play it and wait a moment for it. */
	  play_midi(music_object->dat);
	  ...
	  /* Destroy unneeded music. */
	  unload_datafile_object(music_object);

RETURN VALUE

       Returns a pointer to a single DATAFILE element whose `dat' member points to the object, or NULL if there was  an  error	or  there  was	no
       object with the requested name. Remember to free this DATAFILE later to avoid memory leaks, but use the correct unloading function!
