How can I return a value from a thread in Ruby?

Question

If I have the following code :

threads = []
(1..5).each do |i|
  threads << Thread.new { `process x#{i}.bin` } 
end
threads.each do |t|
  t.join
  # i\'d l         


        

Answer 1

Just use Thread#value:

threads = (1..5).collect do |i|
  Thread.new { `echo x#{i}.bin` }
end
threads.each do |t|
  puts t.value
end
