If you want to compile and run the shell from Part II/III of the tutorial, you can do so by navigating to the subdirectory and then running gcc:

cd part2-3/
gcc -o shell main.c source.c scanner.c parser.c node.c executor.c prompt.c

If you want to compile Parts IV and above, navigate to the subdirectory and run make:

cd part4/
make

Now you can run the shell by invoking:

./shell
