Looks like no one read Hannu's email, including Hannu! ;-)
The output included clearly shows that his Cygwin installation
contains the default path setting from /etc/profile. Cygwin paths
are first. There override the Windows path. The Windows 'find'
*is* hidden by the Cygwin version (see below). So are other like
named facilities. That's why the Cygwin installation constructs
the path this way. While Hannu prescribes this as a viable option,
it would appear that he didn't recognize that this was the option
being used before posting, since his email states that Cygwin does
exactly the oppposite with the path. It does not.

Subject: Re: DOS <-> Bash interaction...
Umm, I don't think this is dependent on the Windows version... My
(mostly standard, slightly edited) /etc/profile *prepends*
"/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/X11R6/bin" to the
PATH... Yours probably does too. Thus, /bin/find.exe should hide
/cygdrive/c/WINDOWS/COMMAND/find.exe (which your cygcheck output snippet
confirms).
You can always check which program will be invoked by typing "type -a
programname" in bash. For "find.exe" you should get something like:
$ type -a find.exe
find.exe is /usr/bin/find.exe
find.exe is /bin/find.exe
find.exe is /cygdrive/c/WINDOWS/COMMAND/find.exe
If you get something different as the first entry, your /etc/profile does
*append* the standard paths to the contents of $PATH. This means you've
probably changed it at some point in the past. Change it back.
