You are given a text fi le with 10,000 lines. The fi le contains two columns of data, and you must change the order of the columns. You can do so quickly and accurately by using the cut and paste commands. Suppose you did not have these commands? Using any other tools at your disposal, how might you accomplish the job? Consider using a text editor, word processor, a spreadsheet program, writing a program of your own, and so on. Is there anything you can think of that is easier than the Unix cut and paste programs? Why is this? What qualities do the programs in this chapter have that make them so useful?
