Java Creation of output file from list of file

Hi Guru's,

Eventhough I know basic shell scripting, Iam not an expert.
Can any one help me to get a logic/answer for the below requirement:

I've to create an output file "outputfile.txt" from many datafiles (ex: abc.dat, xyz.dat).
Header record layout for "outputfile.txt" should be $variable1 (from position 1-1), $variable2 (from position 16-20) and filled with space (from 021-121).

I've a list file "listfile.lst" which has the datafile names.
I've to read these file names one by one.
From each datafile I've to extract only detail records and have to appended to "outputfile.txt"

Can we do this thorough shell scripting or do we need to use awk?

Amy help would be much appreciated.

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. SEE ALSO
