Sounds like a typo.  (It is easy to change a volume name.)

Launch the disk utility (Applications/Utilities/Disk Utility) and see  
what it shows.
The files imply that it is/was a user account, or something that  
someone was playing with.

The "normal" top level files for a volume should be:
Desktop DB
Desktop DF

bin, cores and sbin imply that somebody was "playing" ... installing  
something "non-apple."

Yes, the default shell is bash.
Keep in mind that the default path is NOT DEFINED.

Yes, OSX is VERY BSD/OSF  like, but with LOTS of Apple modifications.

The default profile for terminal is defined in a directory, you will  
have to create in your home directory.

The file in that is called: environment.plist

Plists are basically xml files. (gone are the days of flat files...  
sigh). You can handcraft it or use plist editor,
which unless you have the Developer CD installed, you won't have...


This is my:      .MacOSX/environment.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd 
<plist version="1.0">

 From the sounds of things, I would strongly recommend that you find  
the original OSX CDs, wipe the disk and re-install.
There is nothing worse than trying to learn from something that is  
brain-dead  because someone else has lobotomized it
to begin with... and yes, there ARE significant differences between  
10.4 or earlier and the current 10.5 , aka Leopard.
