pretty print to a file in ruby

Question

I am trying to pretty print a hash to a file.

I tried unix redirects [added different flags to it incrementally] :

`echo #{pp  mymap} | tee summary.out          


        

Answer 1

Doing something similar to what Edu suggested and How do I redirect stderr and stdout to file for a Ruby script? helped.

Here is how the new code is similar to:

$stdout.reopen(@dir_+"/my_file.out",'w+')
puts "All metrics are:"
pp final_map
$stdout=STDOUT

Would still be interested to know why redirection operators > , and 2>&1 in back-ticks doesn't work
