Subject: Re: Redirecting $stdout and $stderr streams

I don't know where you're headed with this, but this is what I use to 
create a logfile when I'm not running from a console:

begin

#Output log
orig_std_out = STDOUT.clone #Make a record of the default console output 
to return to it later
$stdout.reopen("Rubylog.txt", "w") #Create / overwrite logfile
$stdout.sync = true #Allow interception of console output
$stderr.reopen($stdout) #Pass errorserrors to logfile

#Do stuff...
puts "I'm doing stuff!"

rescue

puts %Q|Fatal error occurred:\n#{$!}\n\nDebugging 
Information:\n#{$@}|,"Error" #Logfile output

ensure

STDOUT.reopen(orig_std_out) #Restore output to console

end
