Subject: IO.popen   exit the program when it failed

i have been trying to recieved the output of a command with IO.popen and
it works great but if i place a unknown command to the system the ruby
program terminates.

def comando ( inputcmd )
  f = IO.popen(inputcmd)
  output = f.readlines
  return output
end


#########################################################
there is a loop calling the method like this:
#########################################################


      cliente.puts "Escriba el comando a ejecutar por cmd.exe: "
      inputcmd = cliente.gets
      cliente.puts comando( inputcmd )


any help will be appreciated!!

Thank you!
