Hi, I am working with files containing 2 columns in which i need to come up with the frequency/count of values in col. 2 falling within specifics binned values of col. 1. the contents of a sample file is shown below:
15 12.5
15 11.2
16 0.2
16 1.4
17 1.6
18 4.5
17 5.6

Hi All,
I have the following time stamp data in 2 columns
Date TimeStamp(also with milliseconds)
05/23/2012 08:30:11.250

Hi, I wanted to calculate cumulative frequency distribution of my data that involves several arithmetic calls. I did things in excel but its taking me forever. this is what I want to do:
var1.txt contains n observations which I have to compute for frequency which is given by 1/n and subsequently... (7 Replies)
I wanted to know the Red Hat Linux command for cumulative disk space usage and the free space as df -h gives used and free space individually for the drives. Or, a command to check free space on the server would also be fine.
I hope, my question is clear.

Hello all,
I got some time duration data like below and I want to compute the cumulative elapsed time. The data is in MM:SS.SS format. I got struck with logic on what to do when it changes from 59:59.ss to 00:00.ss.
59:59.4
59:59.6
59:59.9
00:00.1
00:00.4

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)
I have a file has thousands of rows and each row has a number and the number can be positive or negative. I want to do the cumulative sum from the first row. How can I find out the maximum cumulative value when I do the sum work row by row. Here is the example:

fmscan - scan FM band for radio stations
SYNOPSIS
fm [ -h ] [ -d device ] [ -t tuner ] [ -s freq ] [ -e freq ] [ -i freq ] [ -q ]
DESCRIPTION
fmscan is a program to scan a frequency band for radio stations, using the video4linux interface introduced in 2.1.x series Linux kernels.
It shows which ones have a accumulated signal strength of 50% or higher.
OPTIONS
-h Print a usage message to standard output, and exit.
-d device
Sets device as the device to tune. The default is /dev/radio0.
-t tuner
Sets tuner as the tuner on the selected device to adjust. The default is tuner 0. Most radio devices have only a single tuner.
-s freq
Starting frequency for scan, in MHz. Default: 87.9.
-e freq
Ending frequency for scan, in MHz. Default: 107.9.
-i freq
Increment between scanned channels, in MHz. Default: 0.2.
-t percent
Signal strength threshold to consider a channel. Default: 50%.
-q Quiet mode. Suppresses progress output.
BUGS
This process can take a while, and results vary greatly depending on the radio card in use. If your card's hardware cannot report signal
strength, it will not produce useful results.
This program may not do much if your radio card's driver doesn't support fine tuning in 1/16000 MHz offsets. By default, V4L2 assumes 1/16
MHz tuning units, which introduces evil rounding errors on many frequencies.
Supports only tuner 0 on any given device.
