Thanks for the corrections.

But bash is clearly doing something right, as:

bash-3.00$ ls -l /cygdrive/c/oracle/product/10.1.0/db_1/bin | grep -i 
exp.exe
----------+ 1 shankar        None     405776 Mar  8  2004 EXP.EXE
bash-3.00$ which exp
/cygdrive/c/oracle/product/10.1.0/db_1/bin/exp
bash-3.00$ which exp.exe
/cygdrive/c/oracle/product/10.1.0/db_1/bin/exp.exe
bash-3.00$ which EXP
/cygdrive/c/oracle/product/10.1.0/db_1/bin/EXP
bash-3.00$ which EXP.EXE
/cygdrive/c/oracle/product/10.1.0/db_1/bin/EXP.EXE

And it's able to run the program using any of those 4 unqualified names 
(exp, exp.exe, EXP, EXP.EXE).

But tcsh is lost:

EXP.EXE: Command not found.

Huh? But:

 > exp

 > exp.exe
exp.exe: Command not found.
 > EXP
... output from Oracle EXP
 > EXP.EXE
... output from Oracle EXP


I wonder if tcsh can pick up some lessons from bash...

Oh, I'm running cygwin1-20050914.dll (on top of cygwin 1.5.18-1), and 
tcsh 6.14.00-5.
