File Comparision by using Shell Script
Hello All,
I am trying to find 2 file comparision by using Shell Script. For example, I am having 2 directories namely DAY1 & DAY2. DAY1 directory contains file1.dat, file2.dat, file3.dat, file4.dat, file5.dat & DAY2 directory contains file1.dat, file2.dat, file3.dat, file4.dat, file5.dat. Now, want to compare DAY2/file1.dat with DAY1/file1.dat and store the result in tmp file, .... DAY2/file5.dat with DAY1/file5.dat and store the result in tmp file like. I.e., DAY2/file1.dat first row checkes with each rows in DAY1/file1.dat and so on. How to do in Shell Script. File row length is dynamic and this shell script is to run interactively by using batch jobs in UNIX. Does anybody use this requirement in your project or suggest me how to do this approach. In fact, I am new to UNIX shell scripting.
Regreat your suggestions/help.
Regards
Venkat.

load_datafile
load_datafile(3alleg4) Allegro manual load_datafile(3alleg4)
NAME
load_datafile - Loads a datafile into memory. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
DATAFILE *load_datafile(const char *filename);
DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate
key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example:
/* Load the resources for our game. */
DATAFILE *dat = load_datafile("game.dat");
if (!dat)
abort_on_error("Couldn't load sound resources!");
/* Use resources. */
...
/* Destroy them when we don't need them any more. */
unload_datafile(dat);
RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks.
