Humm I just ran the setup. I did a "ls -1 | wc" on both /bin and /usr/bin
and got the same number. I wonder if it is a link.

Yes this was a typo should have been bash-3.1$

Trying to get the email out as my wife calls saying she is downstairs ready
to take me home.

I have a script called test.sh in /local/adminscripts. /local is a directory
that I made. The script is 

	#! /bin/sh
	echo "HELLO WORLD"

in a W2K3 command prompt (DOS) window 

	C:\cywin\bin>     (which is the command prompt prompt)

I type the command

	c:\cygwin\bin\bash -c "/local/adminscripts/test.sh"

It returns

	bash-3.1$

and waiting for input. I then type exit and the script executes. The output
is like this:

bash-3.1$ exit
exit
HELLO WORLD

C:\cywin\bin>   (which is the command prompt prompt)
