So as I was learning about the filesystem and familiarizing myself, I came upon this interesting tidbit about /dev and how /dev/dsp can be particularly utilized.
/dev/dsp is essentially your speaker.
Take a command like so: [code]cat /etc/host.conf > /dev/dsp[/code]
You will hear something.
What was that?
It was your host.conf file!
Hopefully I wasn't the only one who didn't know this :rolleyes:
Ahaha that's pretty cool :). What happens if you do that with a sound file? Surely it wouldn't work since it's encoded.

Nah, it wouldn't work with mp3 and the likes, but raw audio files (unsigned wav?) may work, except they'd probably sound much quicker as it's ignoring the samplerate.
Also,
cat /dev/kmem > /dev/dsp - play the kernel memory!
sudo tcpdump -l -a -vv > /dev/dsp - play network traffic
cat /dev/fb0 > /dev/dsp - play what's currently on your screen (framebuffer)
cat /dev/sda > /dev/dsp - play your first hard drive (usually).
Distros using ALSA can supplement "> /dev/dsp" with "| aplay", and with Ubuntu, "| paplay" (if you're using PulseAudio).
Oh, thanks - I like the network traffic one.
Listen to intertubes!
Ran that in the terminal and didn't hear anything? Just an endlessly growing line of "~~~~~~~~~~~~~"
Did I do something wrong? On Linux Mint 32-bit GNOME.
Internet goes RRRRRRRRRRRRRRRRRRRRRRRRRRR.
Its horrible then I just exited the terminal forgot to stop it and I had to restart.
Ran a random tar file sounded like white noise with a Ping every once in awhile.
