Your requirement is not quite clear.
The following reads numbers of files from arguments, or from stdin if no arguments are provided.
The numbers in files or stdin can be placed in columns or rows or both

Helo guys, this is not specifically a C programming problem for the unix platform, but a problem i came across in class:

Hi,
I have MyLog.log file, and it contains "*** response Time 150",
I want to develop Unix script like ,
1. extract all such occurances in the MyLog.log file and
2. compute the average time taken
I am new to Unix, any one can give any idea/sample code for this?
Thanks in advance. (1 Reply)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)

Hello,
I am working with a perl script that tries to find the average "frequency" in which lines are duplicated. So far I've only managed to find the way to count how many times the lines are repeated, the code is as follows:
perl -ae'
my $filename= $ENV{'i'};
open (FILE, "$filename") or... (10 Replies)
so I've made a shell script that downloads 6 files in succession from a given url, then deletes them. Now I want to time the script, and the average time it uses by running it ~100 times. My problem is tho, how do I store the time it takes for each run through of the script? I know time writes to... (3 Replies)

pnmconvol
pnmconvol(1) General Commands Manual pnmconvol(1)NAME
pnmconvol - general MxN convolution on a portable anymap
SYNOPSIS
pnmconvol convolutionfile [pnmfile]
DESCRIPTION
Reads two portable anymaps as input. Convolves the second using the first, and writes a portable anymap as output.
Convolution means replacing each pixel with a weighted average of the nearby pixels. The weights and the area to average are determined by
the convolution matrix. The unsigned numbers in the convolution file are offset by -maxval/2 to make signed numbers, and then normalized,
so the actual values in the convolution file are only relative.
Here is a sample convolution file; it does a simple average of the nine immediate neighbors, resulting in a smoothed image:
P2
3 3
18
10 10 10
10 10 10
10 10 10
To see how this works, do the above-mentioned offset: 10 - 18/2 gives 1. The possible range of values is from 0 to 18, and after the off-
set that's -9 to 9. The normalization step makes the range -1 to 1, and the values get scaled correspondingly so they become 1/9 - exactly
what you want. The equivalent matrix for 5x5 smoothing would have maxval 50 and be filled with 26.
The convolution file will usually be a graymap, so that the same convolution gets applied to each color component. However, if you want to
use a pixmap and do a different convolution to different colors, you can certainly do that.
At the edges of the convolved image, where the convolution matrix would extend over the edge of the image, pnmconvol just copies the input
pixels directly to the output.
