1) Yes
2) How do you want to convey the target path to the script? In case you want to use the source files' path, and this is constant, to place the hd*.txt files next to the sources, try (in the END section)
assuming the FILENAME variable is still defined and valid in that section.
Else you can use awk's -v mechanism to supply the path.
hi.i want to create a bash script called countfiles.sh, that will count the pack of files under the current file that their term satisfy a specific pattern. The script must show the total per file or on the whole.

mlib_imagenormcrosscorrel
mlib_ImageNormCrossCorrel(3MLIB)mlib_ImageNormCrossCorrel(3MLIB)NAME
mlib_ImageNormCrossCorrel - normalized cross correlation
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageNormCrossCorrel(mlib_d64 *correl, const mlib_image *img1, const mlib_image *img2, const mlib_d64 *mean2, const
mlib_d64 *sdev2);
The mlib_ImageNormCrossCorrel() function computes the normalized cross-correlation coefficients between a pair of images, on a per-channel
basis.
It uses the following equations:
w-1 h-1
SUM SUM (d1[x][y][i] * d2[x][y][i])
x=0 y=0
correl[i] = -------------------------------------
s1[i] * s2[i]
d1[x][y][i] = img1[x][y][i] - m1[i]
d2[x][y][i] = img2[x][y][i] - m2[i]
1 w-1 h-1
m1[i] = ----- * SUM SUM img1[x][y][i]
w*h x=0 y=0
1 w-1 h-1
m2[i] = ----- * SUM SUM img2[x][y][i]
w*h x=0 y=0
w-1 h-1
s1[i] = sqrt{ SUM SUM (img1[x][y][i] - m1[i])**2 }
x=0 y=0
w-1 h-1
s2[i] = sqrt{ SUM SUM (img2[x][y][i] - m2[i])**2 }
x=0 y=0
where w and h are the width and height of the images, respectively; m1 and m2 are the mean arrays of the first and second images, respec-
tively; s1 and s2 are the un-normalized standard deviation arrays of the first and second images, respectively.
In usual cases, the normalized cross-correlation coefficient is in the range of [-1.0, 1.0]. In the case of (s1[i] == 0) or (s2[i] == 0),
where a constant image channel is involved, the normalized cross-correlation coefficient is defined as follows:
#define signof(x) ((x > 0) ? 1 : ((x < 0) ? -1 : 0))
if ((s1[i] == 0.) || (s2[i] == 0.)) {
if ((s1[i] == 0.) && (s2[i] == 0.)) {
if (signof(m1[i]) == signof(m2[i]) {
correl[i] = 1.0;
} else {
correl[i] = -1.0;
}
} else {
correl[i] = -1.0;
}
}
The two images must have the same type, the same size, and the same number of channels. They can have 1, 2, 3 or 4 channels. They can be
of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT or MLIB_INT.
If (mean2 == NULL) or (sdev2 == NULL), then m2 and s2 are calculated in this function according to the formulas shown above. Otherwise,
they are calculated as follows:
m2[i] = mean2[i];
s2[i] = sdev2[i] * sqrt(w*h);
where mean2 and sdev2 can be the output of mlib_ImageMean() and mlib_ImageStdDev(), respectively.
The function takes the following arguments:
correl Pointer to normalized cross correlation array on a channel basis. The array must be the size of channels in the images.
correl[i] contains the cross-correlation of channel i.
img1 Pointer to first image.
img2 Pointer to second image.
mean2 Pointer to the mean array of the second image.
sdev2 Pointer to the standard deviation array of the second image.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
