Hey Everybody,

I am having much trouble figuring this out, as I am not really a programmer..Smilie

Datafile.txt
Column0 Column1 Column2
ABC DEF xxxGHI

I am running using WGET on a cronjob to grab a datafile, but I need to cut the first three characters from column2 of the file, and save the file. It is Tab-delimited...

Any help at all would be greatly appreciated!!! I have been reading tutorials for hours and I just can't get it!

Thanks in advance,
Rick

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! SEE ALSO
unload_datafile_object(3alleg4), load_datafile(3alleg4), set_color_conversion(3alleg4), find_datafile_object(3alleg4), regis- ter_datafile_object(3alleg4) Allegro version 4.4.2 load_datafile_object(3alleg4)
