I am pretty new to the Rasperry Pi (and linux in general). I am currently using it as an irc bouncer. I have set a `cron` entry to make it check to see if [`znc`](http://wiki.znc.in/ZNC) is running every 10 mins.

```
*/10 * * * *  /usr/bin/znc >/dev/null 2>&1

```

Everything seems to be working fine. But I noticed that there is no `null` folder in `dev`. Does this need to be created?
