Shell Programming and Scripting
awk based script to print the "mode(statistics term)" for each column in a data file

Hi ks_reddy,
you can do two things here..
1) for getting number of columns you can get the number columns from the file and use this as variable as you have suggested.
2) For getting the output in one line better you redirect the output to one file and then you can perform any operation on it.
3) For many number of files just do this one while loop and redirect the output the file which name is appended by the original file.
and length of code doesn't matter too much if we are getting our work done..
