328 CHAPTER 18 INTRODUCING DARWIN AND THE SHELL a good base to build upon where you see fit. I will be using the info in this chapter to build upon in various upcoming parts of this book, beginning with the next chapter where we will take a quick look at adding to the abilities of Darwin by creating our own simple scripts and adding new programs from other sources.
Extending the Power of Darwin After the previous chapter, we hope you are at least somewhat comfortable working in Darwin. In this chapter, we’ll move on and show how to extend the power of Darwin by covering the following: • An introduction to shell scripting • An overview of Perl, Python, and Ruby, which are three powerful scripting languages included with Leopard • How to find and install a range of additional applications using MacPorts and Fink • How to custom compile a Darwin application from the source code Getting Started with Shell Scripting CHAPTER 19 Shell scripting has been a staple in Unix since the first shell. A shell script allows you to add a series of shell commands to a file so that these commands can be easily run over and over. You can see an example of the value of this by examining the start-up process of Leopard. During the start-up, the shell script /etc/rc is started; this file begins a series of processes that effectively start up, configure, and maintain many of the necessary OS and networking functions that occur during start-up. NOTE It’s not recommended that you edit this /etc/rc since it’s possible that your system will not start up correctly if you make a mistake; however, you’ll see that toward the bottom of this script there is a check for the existence of /etc/rc.local. If this file exists, it will include it and execute any scripting contained in it. If you want to include your own scripts that will execute every time you boot the OS, this file should be created if it doesn’t exist (which by default it doesn’t), and your additional start-up scripts should be added to it. Writing a shell script can be as easy as just listing a series of any of the commands you may enter at the command line; however, shell scripts can also accept external variables and may contain simple if...then logic and loops. I’ll briefly explain all of these things, but first let’s take a look at a sample shell script (the line numbers are for reference and shouldn’t be typed into your script): 329
