Le,
Although you don't say it, I assume you're using one or both of the
"--include" "--exclude" options to grep/egrep.
The "check_case:level" CYGWIN environment variable option might be relevant
and the options it provides might be helpful to you. Check it out in the
"using-cygwinenv.html" page of the Cygwin User Guide, from which I excerpt
here:
* check_case:level - Controls the behaviour of Cygwin when a user tries to
open or create a file using a case different from the case of the path as
asved on the disk. level is one of relaxed, adjust and strict.
- "relaxed" which is the default behavior simply ignores case. That's
the default for native Windows applications as well.
- "adjust" behaves mostly invisible. The POSIX input path is internally
adjusted in case, so that the resulting DOS path uses the correct case
throughout. You can see the result when changing the directory using a
wrong case and calling /bin/pwd afterwards.
- "strict" results in a error message if the case isn't correct. Trying
to open a file Foo while a file fOo exists results in a "no such file or
directory" error. Trying to create a file BAR while a file Bar exists
results in a "Filename exists with different case" error.

Grep is case sensitive with respect to Windows 2000 file names. This
causes a problem across various directories, e.g., -r.
I found a discussion back in '97 on this topic - no visible action
resulted. Has there been no decision to TOUPPER() filenames in the
Windows implementation, or has another work around been implemented that
I'm not seeing?
