Linux’s terminal commands are powerful, and Linux won’t ask you for confirmation if you run a command that won’t break your system. It’s not uncommon to see trolls online recommending new Linux users run these commands as a joke.
rm -rf / – Deletes Everything!
The command rm -rf / deletes everything it possible can, including files on your hard drive and files on connected removable media devics. This command is more understandable if it’s broken down:
rm – Remove the following files.
-rf – Run rm recursively (delete all files and folders inside the specified folder) and force-remove all files without prompting you.
/ – Tells rm to start at the root directory, which contains all the files on your computer.
