One utility that can simplify life in key situations is sed. There are so many different utilities, in fact, that it is next to impossible to know and understand all of them. There are also fun things to try, hardware, free programming books and tutorials, and much more.One of the best things about the Linux operating system is that it is crammed full of utilities.
