IIRC, /dev/urandom will provide continuous random data as long as a process
attempts to read from it. Basically it is a never ending file of gibberish
(if you tried to open it in a text editor or at it to the screen). So dd
would attempt to just keep pumping that data into /dev/null, and since that
just discards the data, you would never run out of file space, and hence,
the process would run indefinitely.
So if you *did* start the process. You could probably just stop it by a
<Ctrl>-C on the same console you issued the command, or on a separate
console, use ps to find the process number of that dd command, and then
issue a kill [process number]. Nice and simple. Or even easier, you could
probably get away with "killall dd".
