A general purpose script that allows me to automate calls to remote systems

spwn.rb

#!/usr/bin/ruby
require 'expect'
require 'pty'
commands = %Q(
/etc/init.d/check_rep status
)

File.foreach('hosts'){|host|
  puts host.strip
  PTY.spawn("ssh -i nso.key #{host}"){|o,i,p|
	#o.sync = true
	#i.sync = true
	$expect_verbose = true  # shows actions on screen
	if o.expect("#")
		i.puts("#{commands}")
		o.expect(/[#$]/)
		i.puts('exit')
	end
	begin
		o.each_line{|k|
			puts k
		}
	rescue Errno::EIO
	ensure
		Process.wait p
	end 
	}  
}
