Thanks, Jan.  I was actually looking at that page, and totally glossed

And don't forget about the registry setting you need in order to turn on 
case sensitivity:

I realize that cygdrive maps all the letter drives, but I'm trying to
cut down on the typed text.

That's OK, I just need case-insensitive file globbing.  I don't want
to mess with the actual case sensitivity in Win 7 cuz who knows
consequences (human or software) can result.  Besides, I don't have
permissions to change the registry, though I appreciate the awareness.

Seems overly complicated for me. My current fstab looks like this:

C:/Users/home   ntfsbinary,posix=1,user 0 0
none/   cygdrivebinary,posix=0,user 0 0

If I remember correctly the cygdrive thing is what automatically maps
all my C:. D:, E:, etc drives to /C, /D, E and so on.

The magic with posix is described here:
https://cygwin.com/cygwin-ug-net/using.html#mount-table

  posix=0   - Switch off case sensitivity for paths under this mount point
 (default for the cygdrive prefix).

  posix=1   - Switch on case sensitivity for paths under this mount point
 (default for all other mount points).

Unwanted case-insensivity in file name globbing

[Paul]

I just replicated my Cygwin setup on Win 7 (64 bits) onto another Win 7 64-
bit machine, including /etc/fstab

   c: /c ntfs binary,posix=0,user,auto
   d: /d ntfs binary,posix=0,user,auto
   e: /e ntfs binary,posix=0,user,auto
   f: /f ntfs binary,posix=0,user,auto
   g: /g ntfs binary,posix=0,user,auto
   i: /i ntfs binary,posix=0,user,auto
   o: /o ntfs binary,posix=0,user,auto
   r: /r ntfs binary,posix=0,user,auto
   s: /s ntfs binary,posix=0,user,auto

So my home directory "~" is "C:\cygwin64\home\My.User.Name".

I noticed that when I issue a command involving a file name pattern, it is 
not case sensitive in that directory.  For example, "ls -d [A-Z]*" will 
return the folder "cat".  Web searching revealed that it could be the bash 
shell option nocaseglob, but I confirmed that in my case, it is not set:

   $ shopt -p nocaseglob

  shopt -u nocaseglob

I am also puzzled by the fact that when I cd to a subdirectory, the 
unwanted case insensivity is no longer present.  I thought that I did 
something wierd in replicating my Cygwin setup, but when I tested my 
original setup on the 1st computer, I found the same selective case 
insensitivity.

What other setting might cause this?  How can I get bonafide Unix behaviour 
in the file name globbing?
