BASH. Need to extract some numbers and take the average
Hey all,
I ran some simulations, of which the output is 100s of files. I've used grep to extract the vital information needed from the files. This has made my task somewhat easier. But I still need to perform some mathematical calculations (average and geometrical average) on the results of the grep command (which is saved to a txt file).
The general format of the output of grep is (just a crude example):
My aim here is to get the average number of cartons (#) needed to pack ## number of eggs. Here I want to average all the a-4, a-6, a-8, and a-10 and then all the b-4, b-6, b-8, and b-10 cartons. SO my end result is to have an average number of cartons for both a and b. As you can imagine doing this by hand with results that can go up to 100 is very time consuming. Can someone please assist me with a BASH script that can make my job simpler?
Hi ppl,
I am a bit lost on this...can some one assist. I know this can be down with awk or sed, but i cant get the exact syntax right.

Hi all,
I have a list of numbers. I need an awk command to find out the numbers of elements (number of numbers, sort to speak), the average value the min and max value. Reading the list only once, with awk.
Any ideas?

Hello
I have created next scritpt to do the next: chekp if host is alive. When the host down, launch telnet other equip to do checks.

For the data
I would like to parse down and for each parsing
I want a cumulative averaging, stored in an array
that can be output.
I.e.
546/NR = 546
(546+344)/NR=(546+344)/2 = etc.
For N record input I want N values of the average (a block
averaging effectively)
Any... (3 Replies)

Hello All,
What is load average and how is it computed in Solaris 10?
What are the different ranges for normal, warning and danger signs?
Kindly clarify.

get-oui
GET-OUI(1) General Commands Manual GET-OUI(1)NAME
get-oui - Fetch the arp-scan OUI file from the IEEE website
SYNOPSIS
get-oui [options]
DESCRIPTION
get-oui fetches the Ethernet OUI file from the IEEE website, and saves it in the format used by arp-scan.
The OUI file contains all of the OUIs (Organizationally Unique Identifiers) that have been registered with IEEE. Each OUI entry in the
file specifies the first 24-bits of the 48-bit Ethernet hardware address, leaving the remaining 24-bits for use by the registering organi-
sation. For example the OUI entry "080020", registered to Sun Microsystems, applies to any Ethernet hardware address from
08:00:20:00:00:00 to 08:00:20:ff:ff:ff inclusive. Each OUI assignment represents a total of 2^24 (16,777,216) Ethernet addresses.
Every major Ethernet hardware vendor registers an OUI for their equipment, and larger vendors will need to register more than one. For
example, 3Com have a total of 37 OUI entries. Organisations that only produce a small number of Ethernet devices will often obtain an IAB
registration instead. See get-iab(1) for details.
This script can be used to update the arp-scan OUI file from the latest data on the IEEE website. Most of the Ethernet addresses in use
belong to an OUI registration, so this is the most important of the files that arp-scan uses to decode Ethernet hardware addresses. You
should therefore run get-oui occasionally to keep the arp-scan OUI file up to date.
The OUI data is fetched from the URL http://standards.ieee.org/regauth/oui/oui.txt and the output file is saved to the file ieee-oui.txt in
the current directory. The URL to fetch the data from can be changed with the -u option, and the output file name can be changed with the
-f option.
The ieee-oui.txt file that is produced by this script is used by arp-scan to determine the Ethernet card vendor from its hardware address.
The directory that arp-scan will look for the ieee-oui.txt file depends on the options used when it was built. If it was built using the
default options, then it will look in /usr/local/share/arp-scan.
OPTIONS -h Display a brief usage message and exit.
-f <fn>
Write the output to the specified file instead of the default ieee-oui.txt.
-u <URL>
Use the specified URL to fetch the raw OUI data from instead of the default http://standards.ieee.org/regauth/oui/oui.txt.
-v Display verbose progress messages.
FILES
ieee-oui.txt
The default output file.
EXAMPLES
$ get-oui -v
Renaming ieee-oui.txt to ieee-oui.txt.bak
Fetching OUI data from http://standards.ieee.org/regauth/oui/oui.txt
Fetched 1467278 bytes
Opening output file ieee-oui.txt
9274 OUI entries written to file ieee-oui.txt
NOTES
get-oui is implemented in Perl, so you need to have the Perl interpreter installed on your system to use it.
get-oui uses the LWP::Simple Perl module to fetch the data from the IEEE website. You must have this module installed on your system for it
to work. This module is available on most distributions, often called libwww-perl. It is also available in source form from CPAN.
You can use a proxy server by defining the http_proxy environment variable.
