Executable cygwin script in windows

Hello,
I have a cygwin command/bash script that I want to run on a group of txt files in a folder in windows. Basically, I want to make a .bat file that can be copied into the folder containing my files, and can be double clicked to open a cygwin window that will run the script from within the folder and stay open to show the output.
So if my folder is c:/stuff, I copy the bat file to c:/stuff, then double click the bat file to open a cygwin bash shell at /cygdrive/c/stuff which runs myscript on the txt files contained therein. Is this possible? and how may it be achieved.

Whenever i make a bat file in notepad containing the line c://cygwin/bin/bash.exe mycommand it opens a bash shell within that working directory but doesnt run the script, and none of the commands work.

Below is a copy of a script I use to
"start" an X-window session.

The script is called startx.bat, and
I invoke it by double clicking its shortcut on my desktop.

You will notice that the commands in the
script are primarily "Windows" commands...
...Including invoking "bash"...
The trick is specifying the -C argument to bash, which tells it to "run this command".

@echo off

C:
chdir C:\cygwin\bin

bash -c "PATH=$PATH:/bin:/usr/bin;XWin -clipboard -logverbose 3 -ac -query cdcxvd0559.con-way.com -fp \"tcp/cdcxvd0559.con-way.com:8000,/usr/share/fonts/100dpi/,/usr/share/fonts/75dpi/,/usr/share/fonts/Type1/\" "

HTH,

Thanks that really worked. Is there a way of compiling a shell script so it produces a standalone windows executable for friends who dont have cygwin?
