Playing with tor in command lines

torloop.rb

#!/usr/bin/env ruby

# Usage: ./torloop <command>
#
# Runs a command over and over again with
# a new tor identity each time.
#
# The command should use the tor network
# under socks5 proxy on port 9050.
# 
# If you want tor output, `tail -f tmp/out`

# Kill process on 9050 port
