I have a file with more than 2,000 rows like this:
Code:
05/26/2011,1200,1500
I would like to create a awk shell script that calculate the price average of the second and third field each 5,10 and 20 rows or ask me for the values, starting at first row.
Finally compare the average value obtained with the price of last row of the range used for the average, so know whether price is up or down.
I'm fairly new to python so bare with me. I'm trying to write a script that would calculate my class average from exams. The script will look at a text file formatted like this:
Calculus 95 90 92
Physics 80 85 92
History 90 82 83 95
The output should look like this:
Calculus 92.33... (2 Replies)

Hi all
Bit of a silly question, but if I run sar to get the CPU stats (something like this):
sar -u 300 1
The figures that are returned, is it in the above case the average over 300 seconds, or does it just wait for 300 seconds before obtaining the readings? (1 Reply)

Hi everyone,
Has anyone figured out yet how to do pivot table averages using AWK. I didn't see anything with regards to doing averages.
For example, suppose you have the following table with various individuals and their scores in round1 and round2:

pamdeinterlace
pamdeinterlace(1) General Commands Manual pamdeinterlace(1)NAME
pamdeinterlace - remove ever other row from a PAM/PNM image
SYNOPSIS
pamdeinterlace [-takeodd] [-takeeven] N [infile]
You can use the minimum unique abbreviation of the options. You can use two hyphens instead of one. You can separate an option name from
its value with white space instead of an equals sign.
DESCRIPTION
pamdeinterlace Removes all the even-numbered or odd-numbered rows from the input PNM or PAM image. Specify which with the -takeeven and
-takeodd options.
This can be useful if the image is a video capture from an interlaced video source. In that case, each row shows the subject 1/60 second
before or after the two rows that surround it. If the subject is moving, this can detract from the quality of the image.
Because the resulting image is half the height of the input image, you will then want to use pamstretch or pnmscale to restore it to its
normal height:
pamdeinterlace myimage.ppm | pamstretch -yscale=2 >newimage.ppm
OPTIONS -takeodd
Take the odd-numbered rows from the input and put them in the output. The rows are numbered starting at zero, so the first row in
the output is the second row from the input. You cannot specify both -takeeven and -takeodd.
-takeeven
Take the even-numbered rows from the input and put them in the output. The rows are numbered starting at zero, so the first row in
the output is the first row from the input. This is the default. You cannot specify both -takeeven and -takeodd.
