Ah, those were the days! In dos, "cd" meant change directory. Wish I
could use some of the dos commands in Vista.

The period is shorthand for the current directory. Normally in Windows it
isn't used. In *nix it's used a lot.

'cd' is 'change directory'.
'cd' changes to home directory.
'cd .' changes to the current directory - i.e. where you alread are - not
very useful.
'cd ..' changes to the parent directory - i.e. one level up.

"cd" is "change directory". "." means the current directory, and ".."
means the parent directory. So "cd ." means "change to the current
directory". Since you're already there, that means you've told the
machine to do nothing and that's what it's doing.

That's Unix (and presumably Linux) behavior. Those systems have the
concept of a home directory for each user. Windows doesn't have that
concept, and AFAIK, using CD without any destination does nothing.

CD and CD. do nothing on Linux, either.

Actually, using CD on *nix generally generates a 'command not found'
error.

Well, to be pedantic, yes it does!

CD\ takes you back to the root directory.

Sure, because \ is the name of the root directory.

Almost missed that one. Unix systems are case sensitive, you have to
type the command in lower case.

cd

cd , cd ., cd, do nothing on windows [vista]
cd.., cd .. steps backwards up the path tree by one directory.
cd\ all the way to the root.

Displays the name of or changes the current directory.

CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]

.. Specifies that you want to change to the parent directory.

Type CD drive: to display the current directory in the specified drive.
Type CD without parameters to display the current drive and directory.

Use the /D switch to change current drive in addition to changing current
directory for a drive.

If Command Extensions are enabled CHDIR changes as follows:

The current directory string is converted to use the same case as
the on disk names. So CD C:\TEMP would actually set the current
directory to C:\Temp if that is the case on disk.

CHDIR command does not treat spaces as delimiters, so it is possible to
CD into a subdirectory name that contains a space without surrounding
the name with quotes. For example:

cd \winnt\profiles\username\programs\start menu

is the same as:

cd "\winnt\profiles\username\programs\start menu"

which is what you would have to type if extensions were disabled.

cd without arguments prints the current directory path.

You can't post in here without starting an argument
