The Linux🐧 commands you should NEVER use.
Disclaimer DON'T🚫 run these commands.

A thread🧵👇

1. Recursive Deletion🔁🗑️
This is one of the most dangerous commands. Once this command is run, it deletes all the content of the root directory forcefully and recursively. Thus, all your directories and subdirectories will be deleted and the data will be lost.

2. Fork Bomb🍴💣

My personal best😄,this is a simple bash recursive function which once executed creates copies of itself which in turn creates another set of copies of itself. This consumes the CPU time and memory. Thus, it runs recursively until the system freezes.
