Can anybody point me to an open source automation tool for the functional testing of a CMD line application.
What does your application do? How does your application work? And what do you intend to test? Is it a client/server app? There are no magic automation "bullets", if you just need to launch your app and various paramters, you can use a batch file.
A good rule of thumb is to never measure with your thumb.
I use batch files to automate command line applications.

most scripting languages (Perl/Python/Ruby) would be great choices.
