Hi,
I'm newbie to Unix. I'd like to count the total size of those files in my directory by date. For example, files on this period 05/01/08 - 05/31/08. If possible can we count by byte instead of kb.
if I use $ du - ks , it will add up all files in the dir.
thanks,
Helen (5 Replies)
Hi,
I am trying to get the total file size for certain files per directory.
I am using
find /DirectoryPath -name '*.dta' -exec ls -l {} \; | awk '{ print $NF ": " $5 }' > /users/cergun/My\ Documents/dtafiles.txt
but this lists all the files in the directories.
I need the total... (9 Replies)

Hi
I have some set of files for a particular date. What is the command that I need to put in for finding the total size of all the files for that particular date. The following command is fetching me the size of all individual files seperately

If I have a number of files in a directory, for example,
test.1
test.2
test.3
abc.1
abc.2

and I need to find the total file size of all of the test.* files, I can use du -bc test.* in Linux.
However, in Solaris, du does not have the -c option. What can I do in Solaris to get... (11 Replies)

mlib_imagenormcrosscorrel_fp
mlib_ImageNormCrossCorrel_Fp(3MLIB)mlib_ImageNormCrossCorrel_Fp(3MLIB)NAME
mlib_ImageNormCrossCorrel_Fp - normalized cross correlation
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageNormCrossCorrel_Fp(mlib_d64 *correl, const mlib_image *img1, const mlib_image *img2, const mlib_d64 *mean2, const
mlib_d64 *sdev2);
The mlib_ImageNormCrossCorrel_Fp() function computes the normalized cross-correlation coefficients between a pair of floating-point 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_FLOAT or MLIB_DOUBLE.
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.
In some cases, the resulting coefficients of this function could be NaN, Inf, or -Inf.
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.
