Why not use LWP rather than wget to make it a little more flexible - someone may want to run it on a machine that doesn't have /usr/local/bin/wget - also seeing breakout to shell like this imho best avoided - especially when the alternative is only a couple extra line. Also I would tend to drop a couple extra lines to allow it to be called as a cgi by writing a content header if suitable $ENV values are seen. That way you save the need to to filesystem but if that is what you wanted you could still run from command line and direct to file.
