Subject: Writing A Ruby Shell

Hello all,

    I'm writing a Ruby shell for Ubuntu Linux 7.04. I would like my 
shell to take commands from the user, run the command, output the result 
to the command line, and log the result in a file. But I am having 
trouble getting the Ruby shell to output the result to the command line, 
and log the command. I've tried everything I can think of - using the 
backticks method (``), exec(), system(), and IO.popen, strange 
combinations of the mentioned and eval(), but nothing satisfies both of 
my requirements. Sometimes the shell will output the command result to 
the shell, but it won't log it. Sometimes it will log the command 
result, but it won't output it to the shell. Sometimes it does one or 
both things, but it only outputs or logs some of the command result. I 
would appreciate any help that I could get on ways to make this work.

Thanks,
Philip W.
