Faceless LiveCode App for CLI on Mac OS X and Windows 7

[Bob Cole]

I am looking for an example of how to create a utility program in LC to process a text file on Mac OS X and Windows 7.
I want to put it in a faceless processing stream perhaps with pipes or redirection or options. Such as:
    ...
    cat textfile1 | myLCprogram | more
    ...
or
    ...
    myLCprogram < textfile1 > textfile2
    ...
or 
    ...
    myLCprogram -f textfile1 -o textfile2
    ...

I have read the dictionary about open process and open file but I don't know how to save the LC program without triggering the ui.
What I need is an example of how myLCprogram is structured or wrapped in a shell script that can be used as cli command.  
    Do I need to use -ui somewhere?  
    Do I save myLCprogram as an .app/.exe and run it in a shell like a cgi with a shebang (#! livecode -ui)? 
    Does this only work with LiveCode Server? 
I am a bit confused by it.  A simple example would help tremendously.
Thanks in advance.
