Hi all,
I am new to shell scripting and wanna calculate the mean and standard deviation using shell programming.
I have a file with letters that are repeating and their corresponding duration
a 0.32
a 0.89
aa 0.34
aa 0.23
au 0.012

Hi all,
I want to calculate the standard deviation for a column (happens to be column 3).
Does any know of simple awk script to do this?
Thanks (1 Reply)
Hi I want to use awk to print avg and st deviation but it does not go into a file for column 1 only.
I can do average and # of records but i cannot get st deviation.
awk '{sum+=$1} END { print "Average = ",sum/NR}'

Hello,
I'm trying to create a shell script (#!/bin/sh) which should tell me the age of a file in minutes...
I have a process, which delivers me all 15 minutes a new file and I want to have a monitoring script, which sends me an email, if the present file is older than 20 minutes.

Hi all,
I need to find the standard deviation of each column of a dataset below for each hour. The data is given in 5 second intervals as shown below

I have a file with say 50 columns, each containing a whole lot of data.
Each column contains data from a separate simulation, but each simulation is related to the data in the last (REFERENCE) column $50

Hi All,
I want someone to modify the below script from this forum so that it can be used for all columns in the file( instead of only printing column 3 mean and standard deviation values). I don't know how to loop around all the columns.

PMC_COUNTER_STUDY(1) BSD General Commands Manual PMC_COUNTER_STUDY(1)NAME
pmc_counter_study -- Perform various study's on a systems overall PMC's.
SYNOPSIS
pmc_counter_study
DESCRIPTION
The pmc_counter_study The pmc_counter_study program is designed to run various tests against your systems performance. There are roughly
20-22 canned tests that setup specific PMC's and then run various formulas on the output information. These formulas can be found in Intel
documentation "Using Intel Vtune amplifier xe on NNN Generation Intel Core Processors". The NNN is either 2nd, 3rd or 4th generation i.e.
Sandy Bridge, Ivy Bridge and Haswell. Currently the program only works on these three Intel processor types. You can see the complete list
of formula's by running the program with the -H option. If you know a formula name you can run it by typing -e name. If you know a name and
want what the formula is you can run the program with -e name -h and the program will not run but it will tell you what that name will do (if
known). The -T option can be used to test all PMC's that are known to your system. When running a test you will want to specify -m N where N
is the number of 1 second samples to collect and analize (it bounds the time the test runs). Finally for those that have there own ideas on
what formulas that you want to run you can type your own formula in with -E "formula". The formula can declare directly the PMC's by name or
you can use an abbreviation %NNN. To find out the abbreviations on your system you may run pmc_counter_study -L and it will tell you each PMC
name and the abbreviation you can use. An example of a formula of your own might be -E "FP_ASSIST.ANY / INST_RETIRED.ANY_P" <or short hand on
Haswell> -E " %176 / %150". You must have spaces between each entry and you may use paraenthisis to prioritize the operators. Add (+), Sub-
tract (-1), Divide (/) and Multiplication (*) is supported. You may also introduce constant numbers as well. So for example you can do a
standard efficency test like -E "UOPS_RETIRED.RETIRE_SLOTS / (4 * CPU_CLK_UNHALTED.THREAD_P)".
