-[[[START AT HOME - Slide 28]]]
+Whenever you start up a terminal, you will start in a special
+directory called the *home* directory. Every user has their own home
+directory where they have full access to do whatever they want. In
+this case, the `pwd` command tells us that we are in the `/home/thw`
+directory. This is the home directory for the `thw` user. That is our
+user name. You can always find out your user name by entering the
+command `whoami`.

-[[[FILE TYPES - Slide 29]]]
+When you enter the `ls` command lists the contents of the current
+directory. There are several items in the home directory, notice that
+they are all colored blue. This tells us that all of these items are
+directories as opposed to files.
+
+Lets create an empty file using the `touch` command. Enter the
+command:
+
+    touch testfile
+
+Then list the contents of the directory again. You should see that a
+new entry, called `testfile`, exists. It is colored white meaning that
+it is a file, as opposed to a directory. The `touch` command just
+creates an empty file. 
+
+Some terminals will not color the directory entries in this very
+convenient way. In those terminals, use `ls -F` instead of `ls`. The
+`-F` argument modifies the results so that a slash is placed at the
+end of directories. If the file is *executable* meaning that it can be
+run like a program, then a star fill be placed of the file name.
+
+You can also use the command `ls -l` to see whether items in a
+directory are files or directories. `ls -l` gives a lot more
+information too, such as the size of the file and information about
+the owner. If the entry is a directory, then the first letter will be
+a "d". The fifth column shows you the size of the entries in
+bytes. Notice that `testfile` has a size of zero.
+
+Now, let's get rid of `testfile`. To remove a file, just enter the
+command:
+
+    rm testfile
+
+The `rm` command can be used to remove files. If you enter `ls` again,
+you will see that `testfile` is gone.

+Now, let's move to a different directory. The command `cd` (change
+directory) is used to move around. Let's move into the `UofCSCBC2012`
+directory. Enter the following command:
+
+    cd UofCSCBC2012
+
+Now use the `ls` command to see what is inside this directory. You
+will see that there is an entry which is green. This means that this
+is an executable. If you use `ls -F` you will see that this file ends
+with a star.
+
+This directory contains all of the material for this boot camp. Now
+move to the directory containing the data for the shell tutorial:
+
+    cd 1-Shell
+
+If you enter the `cd` command by itself, you will return to the home
+directory. Try this, and then navigate back to the `1-Shell`
+directory.
