Re:  Some informal chit-chat about directories
Note:  The (( refer to previous comments by Ned

((~ = home dir (not Home dir)
((. = current dir
((.. = parent dir

((In another note you refer to opening the 
(("login directory" by writing 
((chmod a+x .

= chmod 755 .   <= this is used for directories
and chmod 644 filename <= is used to make file public

Poor choice of words by me.  "chomd a+x ." opens the currently
active directory.  I should have done this:
	chmod a+x ~
Or:
	cd  (go to login dir)
	chmod a+x .  (now that we are in our login, it is safe to do this)
I assumed that the chmod would be done right after logging in, before
any cd'ing had been done.

((Is the login dir and home dir (not Home dir)
((the same thing?  Is it true that . and .. are "relative"
(((depending which dir you happen to be in?)

Yes to both.  These are the same:
	cd ~
	cd
	cd $HOME  (not the same as: "cd ~/Home")

Yes, "." and ".." are relative.  You can see which directory you
are in by doing "pwd" (Pring Working Dir)

P.S. to make a directory
% mkdir Directoryname

To delete a directory
% rmdir Directoryname
