PuTTYCS is a small windows application that is intended to be used along with multiple instances of PuTTY (including PuTTYtel, TuTTY, and PieTTY). It's purpose is to send the same command to each PuTTY window. It is can be useful for copying files, starting and stopping processes, and examining logs on multiple servers.
