Technical requirements

All you need for this chapter is a Linux computer with GCC and Make installed, preferably via one of the meta-packages or group installs mentioned in Chapter 1, Getting the Necessary Tools and Writing Our First Linux Programs. It's also preferable if you use the Bash shell for optimal compatibility. Most of the examples will work with other shells as well, but there's no guarantee that everything will work the same way on every possible shell out there. You can check which shell you are using by running echo $SHELL in your terminal. If you are using Bash, it will say /bin/bash.

You can download all the code for this chapter from https://github.com/PacktPublishing/Linux-System-Programming-Techniques/tree/master/ch2.
