I have a file that has about 65000 lines and three columns. I need to read in the first 2 columns until line 112960. I then need to write the 12960 lines of 2 columns to a file.
This needs to be repeated for about 600 files...
I then need to graph the final file values against the index of the file (the file names go from xxx1.txt to xxx600.txt) as a line graph.
How can I go about doing this? I've been toying with one file, but it doesnt seem to work.
