importing text file, removing data and outputting new text file
I have a 800 mb text file that is TAB DELIMITED. It has 25 columns of data.
I only want columns 4,5,13 & 24.
How could I read this file in line by line, remove the other columns
and then write out the included columns to a different text file name
with only 4 columns of data?
Thanks in advance
Pal
