I’m curious how you got a permission denied error in your home directory??

  1. touch grass
  2. chmod 000 grass
  3. touch grass # gets error
  4. Post meme $$$

Yes with one caveat

I don't remember when I made or chmodded this grass file in my home

I just saw it in the directory listing, went "why did I do that", then chuckled and said "I'll post this stupid thing on the internet"

you should have followed the basic linux guide and remove french language with rm -fr / then you wouldn't have any problem

I miss the old days when you could do
ls -R / | aplay

There's no sudo, so it's perfectly safe!!

There was a thing you could do with cat /dev/random into aplay, and get some fun "Music" but you needed some other parameters to get anything other than brown noise.

Mine is basically the same, but since it pipes your filesystem layout into aplay instead of random bits, it's not just brown noise.
It plays you the song of your system.
(also, it can damage your speakers, headphones and/or ears)

Can't vouch for any other distro, but aplay is alive and well on Mint. The package that contains it — alsa-utils — seems to be a core dependency for Cinnamon, even.

So basically, your example runs fine on my machine, screechy sounds and everything.

Toca Raul!

A barreira de linguagem torna um pedido por um tipo específico de musica em uma sugestão imprópria envolvendo o Raul.
