How to keep log messages to a file in JCShell?

I am executing some commands in JCShell (init-update, auth-ext, etc) to communicate with a SmartCard. I would like to address all those log messages to a file, so then I could manipulate them.

What is the command/method to do this?

Thanks

I found the answer:

• Create a file in called e.g. log.txt
• In JCShell: > 3 '<path>\log.txt'

That's all! From now all messages showed in JCShell terminal will be redirected to log.txt file too.
