Once you uncomment them you have to run the script again. You can
run it by doing:
$ . ./.bashrc
or
$ source ./.bashrc
Then the colouring should work in that shell. Or you can log out
and log back in again and the colouring should work in new shells.
But I like the idea of testing the new .bashrc file before
logging out, so that if a serious mistake is made and the script
bombs, you can fix it before you log out.
If it still doesn't work, post the parts of your .bashrc
and .bash_profile (or /etc/login and /etc/bash.bashrc) files
that deal with coloring, and we'll try to help.
Also send the output of the command
$ echo $SHELL

... a new login shell, after the .bash_profile is changed.

Files get included from scripts with the source or dot commands
as above (the source command can be run from the command line
or in a script).

Another good technique!

It's not a vt100 terminal. I'm not entirely sure, I think you
are working at the "console". It _is_ a "terminal", just not
a vt100 terminal.

The output of top changes every 10 seconds or so (configurable), if
you really want to pore over the output and ensure it adds up,
etc, you want ps. You can pipe ps to the screen, or to a file:
$ ps aux > ps.file.txt
Then you can edit the file ps.file.txt, or cat it through less:
$ cat ps.file.txt | less
And examine the contents to your heart's content.

There are different shells, which take commands in different
syntaxes. Debian Linux uses the bash shell, the Born Again Shell.
Similar shells are: sh, ksh (Korn Shell), Bourne shell. All
these are derived from and mostly compatible with sh.
You want to try to make sure your book isn't using C-shell derived
syntax (actually quite likely). The two are really not compatible.
C-shell derived shells are:
csh, tcsh, zsh? and others.

Great stuff, glad you are productive with some things! Makes
learning a lot more fun.
