Hello everyone

I urgently some help with this code. I am trying to implement the
following pipeline and i keep getting this error Erro:ENOENT
can anybody please help me to get this code working


 #input is the command line
def handleCommandLine(input)
      # it splits the pipeline into an array
      command = input.split('|').map{|c|word_list(c)}
       i = 0
       while i< command.length
    commands = command.at(i)
          execute(commands)
    i +=1
     end
     end

   def execute(commands)
    rd, wr = IO.pipe
    if fork.nil?
    # child
    rd.close
    $stdout.reopen(wr)
    wr.close
    exec(*commands)
    exit
    else
    # parent
     wr.close
    $stdin.reopen(rd)
     rd.close
                 end
  end
