CS631 -- Advanced Programming in the UNIX Environment

Code reading exercise

Summary

The objective of this exercise is for you to get used to read (and understand!) code. To this end, please take a look at the NetBSD source code for programs installed under /bin, pick two programs of your liking and inspect the code. Then, read the corresponding code of the same programs in Linux or Open Solaris Illumos. Compare the different implementations. What do they have in common? What makes them different? What surprises you? Is any one implementation easier to read than another?
