Hello

What you need is a CPAN module called POE combined with the POE::Loop::Wx
(the loop for wx that bridges POE and Wx).

It will make it easier for you both to handle the shell command
(POE::Wheel::Run) and to parse the file in non-blocking mode (yield an
event that reads one or several lines at a time until EOF).

You will then have a non blocking Wx application.

You can have a look at the samples included in the POE::Loop::Wx module
and on the http://poe.perl.org website.

It may seem a little difficult at first sight but it's worth.

Thanks
