Subject: [ruby-talk:19311] how to redirect $sdtout

hi,

I am just trying to convert some perl cookbook examples
to ruby for the pleac project (http://pleac.sourceforge.net)

Now I am stuck with the following from chapter 7.0 of the perl cookbook

$old_fh = select(LOGFILE);                  # switch to LOGFILE for output
print "Countdown initiated ...\n";
select($old_fh);                            # return to original output
print "You have 30 seconds to reach minimum safety distance.\n";

my ruby solution does not work!

logfile = File.new("log.txt", "w+")
old = $stdout.clone
$stdout.reopen(logfile)
print "Countdown initiated ...\n";
$stdout.reopen(old)   
old.close
print "You have 30 seconds to reach minimum safety distance.\n";

both strings are written to stdout and the file log.txt is empty.
can anybody tell me why?? I found something similar
in the mailing list archive, but it just doesn't work

regards
markus
