I'd create an array for each of the columns, something like:
But you'd need to modify std_dev to return the value instead of printing it, update the END block, etc.
(I'd give it a go right now, but am having production issues. If you're still fighting it tomorrow, I can tune it up some.)
I have a CSV file that looks like

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}'

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.

Hi,
I have a file containing 100,000 rows-by-120 columns and I need to compute for the standard deviation for each row. Any idea on how to calculate row-wise standard deviation using awk? My sample data looks like this:

Hello there,
I found an elegant solution to computing average values from multiple text files
awk '{for (i=1;i<=NF;i++){if ($i!~"n/a"){a+=$i}else{b++}}}END{for (i=1;i<=FNR;i++){for (j=1;j<=NF;j++){printf (a/(3-b))((b>0)?"~"b" ":" ")};printf "\n"}}' file1 file2 file3

I would like to output the mean and standard deviation of each row so that my final output would look like this

Hello Team,
I am using the following awk script to calculate the SMA (Single Moving Average) for an specific period but now I would like to include the standard deviation output.
Could you please help me to modify this awk shell script

scsi_setup_cdb
scsi_setup_cdb(9F) Kernel Functions for Drivers scsi_setup_cdb(9F)NAME
scsi_setup_cdb - setup SCSI command descriptor block (CDB)
SYNOPSIS
int scsi_setup_cdb(union scsi_cdb *cdbp, uchar_t cmd, uint_t addr, uint_t cnt, uint_t othr_cdb_data);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
cdbp Pointer to command descriptor block.
cmd The first byte of the SCSI group 0, 1, 2, 4, or 5 CDB.
addr Pointer to the location of the data.
cnt Data transfer length in units defined by the SCSI device type. For sequential devices cnt is the number of bytes. For
block devices, cnt is the number of blocks.
othr_cdb_data Additional CDB data.
DESCRIPTION
scsi_setup_cdb() function initializes a group 0, 1, 2, 4, or 5 type of command descriptor block pointed to by cdbp using cmd, addr, cnt,
othr_cdb_data.
addr should be set to 0 for commands having no addressing information (for example, group 0 READ command for sequential access devices).
othr_cdb_data should be additional CDB data for Group 4 commands; otherwise, it should be set to 0.
scsi_setup_cdb() function does not set the LUN bits in CDB[1] as the makecom(9F) functions do. Also, the fixed bit for sequential access
device commands is not set.
RETURN VALUES
scsi_setup_cdb() returns:
1 Upon success.
0 Upon failure.
CONTEXT
These functions can be called from a user or interrupt context.
