HI ALL,
i am a beginner in unix world.
can anyone please tell me the way to find total size taken by each directory (including size of all subdirectories and files) present under /var.
e.g what is space occupied by /var/adm , /var/admin etc.
its a simple question but still i dont know the... (2 Replies)

Hello!
I'm trying to find out the total file size of a subset list in a directory. For example, I do not need to know the total file size of all the files in a directory, but I need to know what the total size is of say, "ls -l *FEB08*" in a directory. Is there any easy way of doing this?

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)

I am trying to get the total size of the folder using the below command
but its not working. any ideas?
du -bc <foldername>/|grep total|tr -s " "|cut -d" " -f1
the output i am getting is

Hi all...
I have a directory called dbrn. This directory contains an unknown number of subdirectories which in turn contain an unknown number of files.

Hi,
Using Redhat, how do I display total hard disk size? I know how to do that in Solaris, you can type, format. It will show how big the disks are.
This is what I did so for.
$ df -t ext3 -h

mlib_imagenormcrosscorrel
mlib_ImageNormCrossCorrel(3MLIB) mediaLib Library Functions 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);
DESCRIPTION
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.
PARAMETERS
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.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
