Summary

In this chapter, we’ve looked at getopts, which gives us a cool and easy way to create scripts that recognize Linux and Unix-style option switches that might have their own arguments. We began with a review of what command options and arguments are, and then cleared up a possible point of confusion about getopt and getopts. After a presentation about how to use getopts, we wrapped up with a review of a couple of real-world scripts that use it.

In the next chapter, we’ll look at how shell scripting can be a big help to security professionals. I’ll see you there.
