win = RUBY\_PLATFORM =~ /(ms|cyg)win|mingw/  
flags = ’ -h now’  
flags = ’ -t 0’ if win  
system “#{‘sudo’ unless win} shutdown #{flags}”

or something like that…

system ‘shutdown -h now’

And you need to be sudo which might be a problem. But that is Ubuntu  
problem now.

Vamsi K.,  
Any command/combination you use in your shell, you can use from ruby too

system “the command”  
or  
return\_value = `the_command`

There are more ways, but system is the easiest one.
