Whew! This tutorial sure has covered a lot of ground, sweeping you through a whirlwind tour of many basic shell programming concepts. While taking this tutorial, you learned many core concepts of shell programming: continuous loops, inline input, reading keyboard input, base conversion, and subshell execution. You also learned how shell code snippets can be run as one-liners right from a shell prompt and how to put them together in a file as an executable script. These are some of the most important shell scripting concepts you can learn. If you use what you learned in this tutorial along with what you learned in the previous tutorials in this series, you're well on your way to becoming a UNIX pro.
