I think you can only use it online.

This is like several of your other threads, where you post without telling us what you've done/tried on your own, and leave out details. "Calculate on a column" can mean different things, but you don't provide ANY samples of the data. You also don't tell us what language you're writing in, or what you're trying to accomplish.

You said in a previous thread of yours that you already write scripts in R...why can't this be done in what you already know? You could put the data into Libreoffice spreadsheet, and 'calculate' from there. You can write a bash script to read the numbers and add them up...and you can also use perl, ruby, python, or any number of other languages.

Show us the sample input data, and what you're trying to accomplish, and what you've done/written on your own so far, and we can try to help.

I am looking for a way to calculate gini index uder linux - bash script will be the best..

Right now i am using CRAN package "ineq" for this calculation and the use is very simple, but i would prefer to not use R/perl/python in this script, because i dont have R in all the machines i want to use this.

I found many solution also with perl/python just by google it.

The kind of input that i have is vectors of numbers, each number in different line,usually 600 lines.
For example:
111
222
333
223
124
....

Ok, so again...post what you have written/tried on your own so far, and tell us where you're stuck.

If you found many solutions using perl/python, why not use those instead of the R scripts, since you don't have R installed on all your machines?

There are lots of examples about how to perform mathematical operations in bash, like this one:

Again, please post what you've written/tried of your own, and tell us where you're stuck.
