Here is my problem:
I have different data files each with several columns and row of data.
datafile1 , datafile2, ...
Now I need to do some simple math procedure of this data files, Lets say I need to add the 3rd column of datafile1 to the 2nd column of the datafile2.
I was thinking to write a shell script that does so, but I am not sure where to start.
I think I need to first open up data files and then take different columns from each of them. I don't know what commands should I use or search for.
Any suggestion is very appreciated.
