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.

CD\ takes you back to the root directory.

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

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

If you're serious: I tried cd without arguments in a command window
before I posted, rather than take a chance on my memory (or the
possibility of a change since I last did it, three or four versions
ago).

I just reread your post. My slowness at getting your pun embarrasses
me.

I shall recover, though. Maybe :-)
