about .plan! How to execute programs within the .plan file

I am currently learning LINUX commands and I am wondering how to run commands within the .plan file. For example i want to a message as would be output from the ~st开发者_如何学Cepp/cosway programs. I typed ~stepp/cosway "HELLO" but it didn't work. What is the command for that?

Also how do I set all files in the current directory and all its subdirectories recursively to have a group of admin?

The .plan file is a plain text file that is served by the fingerd daemon. For security reasons, it's not possible to execute commands from that file, unless you modify and recompile fingerd on your machine to do so.

Concerning the second part of your question, use chgrp:

$ chgrp -R admin *
