If you have an unwieldy text file that you are trying to process, splitting it in sections can sometimes help processing time, especially if we were going to import a file into a spreadsheet. Or you might want to just retrieve a particular set of lines from a file.

Enter split, wc, tail, cat, and grep. (don't forget sed and awk). Linux contains a rich set of utilities for working with text files on the command line. For our task today we will use split and wc.
