CHAPTER 18 INTRODUCING DARWIN AND THE SHELL
Oops, first we need to remove any files in there:
Leopard:~/Documents/Shakespeare scott$ rm Macbeth/*
Leopard:~/Documents/Shakespeare scott$ rmdir Macbeth
Leopard:~/Documents/Shakespeare scott$ ls
tomorrow
Next, we can create an empty file with touch:
Leopard:~/Documents/Shakespeare scott$ touch nothing
Leopard:~/Documents/Shakespeare scott$ ls
nothing tomorrow
Leopard:~/Documents/Shakespeare scott$ cat nothing
Leopard:~/Documents/Shakespeare scott$
More Essential Commands
There are literally hundreds of commands available at the command line, and it would take far
more space than we have in this book to cover them all; however, as you progress through the
rest of the book, you will learn a number of new commands when they are applicable to the
topic at hand. In the meantime, there are a number of essential, or at least very useful, commands
that you may want to know about that don’t fit nicely in a future discussion in this book. They
are covered here.
man
The man command is the command that will explain all others. If you want to learn more about
the ls command, enter man ls, and your terminal will open into a special mode (called a pager)
for reading man pages, which will look something like this:

displayed first; directory and nondirectory operands are sorted separately
and in lexicographical order.
