Thanks Paul, both for your initial reply, and your follow-up.
In this case it's not a matter case sensitivity.
I've verified that, in one of the example cases, there are both *.pdf and *.PDF
files in the subject directory.
Both 'ls *.pdf' and 'ls *.PDF' produce the "ls: cannot access '*.whatever': No
such file or directory" error.
(Nor, to the other respondent's question, as I pointed out in my original post,
is it ACLs, as I did check CACLS before posting).
I also tried copying (using Windows CMD "COPY") *.pdf (so being under Windows,
not Cygwin, it matches all cases) from a subject directory to a new test
directory.
In the resulting copy in the new test directory, the Cygwin shell expansion
problem persists.
Here's an interesting twist:
C:> cd c:\bin\cygwin64\bin
C:> ln gnufind.exe find.exe # I do this to allow me to differentiate between
Windows' built-in very limited FIND command, and GNU/Cygwin's far superior find
command.
C:> cd \my\test\directory
C:> gnufind . -name *.pdf -print
[ successfully returns all *.pdf {lower case only} files in the subject
directory ]
C:> gnufind . -name *.PDF -print
[ successfully returns all *.pdf {upper case only} files in the subject
directory ]
I'm pretty sure that Cygwin 'find' does NOT try to emulate shell globbing the
way 'ls' does, so it makes sense that this works, and it supports the theory
that something weird is going on between how Cygwin does shell expansion when
under Windows CMD vs. when fully within the Cygwin environment (under bash
where of course bash is doing the shell expansion, and ls or other Cygwin
commands don't have to).
Does any of this help pinpoint the problem further?
thanks again,
-Jay

Subject: Re: shell expansion produces e.g. "ls: cannot access '*.pdf': No such
file or directory" in Windows CMD shell, but works okay in bash
Is this because cygwin globbing is (by default) case sensitive? You could set
the CYGWIN environment variable to "glob:ignorecase" to get case-insensitive
behaviour.
