so @su1 will have 6,7,2 @su2 will have 60,70,20 etc..But I dont know how many such files in mu and su..there might be Su9, su10 etc. Runtime I need to check the number of files, get those values and print to one single file. Once I parse the values from each file, i have to print the values in columnwise. I think the solution given by you does an average (some calculation) of all su values in column 1 .. Can u pls help me. ?? Now I have hard coded the number of files to only 3.
