OS users: 
users = File.new("/etc/passwd").collect{|x| x.split(':')[0]}

puts %x[ls|wc].split(/\s+/)[1]
Network interfaces: 
inet = Hash.new{|h,k| h[k.split(/\s/)[0]] = k.scan(/addr:(\d+\.\d+\.\d+\.\d+)/)[0].to_s}

%x[ifconfig].to_s.split("\n\n").collect{|x| inet[x]}

# dump the structure: puts inet.inspect
