From `ri Net::SSH`

       Net::SSH.start("host", "user", :password => "password") do |ssh|
         result = ssh.exec!("ls -l")
         puts result
       end


Sample of my own stuff...
require 'rubygems'
require 'net/ssh'

server = "acid"
user = "jayeola"
Net::SSH.start(server, user) do |x|
  cmd2 = x.exec!("test -d /proc && echo \"OK\"").strip
  p cmd2
  if cmd2 != "OK"
    p "no proc found"
  else
    p "got proc"
  end
  
  cmd3 = x.exec!("test -f /proc/partitions && echo \"OK\"")
  cmd4 = x.exec!("test -f /proc/diskstats && echo \"OK\"")  
end


I'm using this library and it doesn't give me a prompt at all but runs
the code as required. How are you using it?
