Thank you so much. But does that also create a new file and write all the "good" data into it without overwriting?
The scripts shown just write the extracted data to standard output. The original data (datfile1 and datfile2) are not modified. If you want to save the output in files, try something like:
And then look at the contents of the files datfile1.mod and datfile2.mod after it finishes. You could also pipe the output into another stream of processes to do whatever you want with the data without creating temporary files, replace the data in the original files, or millions of other choices depending on what you want to do. If you tell us what you are trying to do, we might be able to suggest saving the output in a manner that would be appropriate for your situation.

I think this should be relatively simple but I can't figure it out. I have several files with the same name in different folders within a directory (the output of a program that I ran). Something like this:

blit
blit(3alleg4) Allegro manual blit(3alleg4)NAME
blit - Copies a rectangular area from one bitmap to another. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void blit(BITMAP *source, BITMAP *dest, int source_x, int source_y, int dest_x, int dest_y, int width, int height);
DESCRIPTION
Copies a rectangular area of the source bitmap to the destination bitmap. The source_x and source_y parameters are the top left corner of
the area to copy from the source bitmap, and dest_x and dest_y are the corresponding position in the destination bitmap. This routine
respects the destination clipping rectangle, and it will also clip if you try to blit from areas outside the source bitmap. Example:
BITMAP *bmp;
...
/* Blit src on the screen. */
blit(bmp, screen, 0, 0, 0, 0, bmp->w, bmp->h);
/* Now copy a chunk to a corner, slightly outside. /*
blit(screen, screen, 100, 100, -10, -10, 25, 30);
You can blit between any parts of any two bitmaps, even if the two memory areas overlap (ie. source and dest are the same, or one is sub-
bitmap of the other). You should be aware, however, that a lot of SVGA cards don't provide separate read and write banks, which means that
blitting from one part of the screen to another requires the use of a temporary bitmap in memory, and is therefore extremely slow. As a
general rule you should avoid blitting from the screen onto itself in SVGA modes.
In mode-X, on the other hand, blitting from one part of the screen to another can be significantly faster than blitting from memory onto
the screen, as long as the source and destination are correctly aligned with each other. Copying between overlapping screen rectangles is
slow, but if the areas don't overlap, and if they have the same plane alignment (ie. (source_x%4) == (dest_x%4)), the VGA latch registers
can be used for a very fast data transfer. To take advantage of this, in mode-X it is often worth storing tile graphics in a hidden area of
video memory (using a large virtual screen), and blitting them from there onto the visible part of the screen.
If the GFX_HW_VRAM_BLIT bit in the gfx_capabilities flag is set, the current driver supports hardware accelerated blits from one part of
the screen onto another. This is extremely fast, so when this flag is set it may be worth storing some of your more frequently used graph-
ics in an offscreen portion of the video memory.
Unlike most of the graphics routines, blit() allows the source and destination bitmaps to be of different color depths, so it can be used
to convert images from one pixel format to another. In this case, the behavior is affected by the COLORCONV_KEEP_TRANS and COLOR-
CONV_DITHER* flags of the current color conversion mode: see set_color_conversion() for more information.
