The server knows you’re piping.

A server can tell you’re piping something directly into bash or sh and change the script it’s sending in realtime to something malicious because it knows you’re not looking at it first:

Make executable just for your user:

Good practice is only making a file executable for your user unless every user needs executable rights:

chmod u+x /path/to/file # Make executable for just your user
chmod +x /path/to/file # Make executable for all users

Better terminal options to Disk Destroyer:

dd may be the official “Disk Destroyer” but cat, tee, pv, tail, ect can all destroy (sorry) clone or write partitions usually better than dd. ‘dd’'s sort of been grandfathered in as THE standard but it’s options and defaults are antiquated and designed for old disks which makes it needlessly confusing and slower when stuff like buffer size really should be automated.

Example using cat:

lsblk # Triple check you're choosing a partition you don't mind destroying.
sudo cat /dev/sdX > myclone.iso # Clone a drive
sudo cat myclone.iso > /dev/sdX # Restore from clone (or write any iso)

To get a progress bar, install pv and use it with it’s -p option, example:

sudo apt install pv
sudo pv -p ./ubuntu-22.04-desktop-amd64.iso > /dev/sdX
# Example Output: [>>>>>>>        ]  50%

Now you can accidentally wipe your main partition the modern way.

So what you’re saying is I should remove

alias neofetch='curl -sSL https://github.com/dylanaraps/neofetch/raw/master/neofetch | /bin/bash'

from my .bashrc?

Simple and fun pranks especially for someone using a dock, or a tower where they can’t see all their USB ports easily, plug a wireless mouse dongle in where they can’t see the dongle and wiggle their mouse in annoying ways. (This works best if you can see their screen)
