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 don't have a clue where to start. Any suggestion is very appreciated.
