The Unix/Linux dd command is also known as “disk destroyer” if you swap if and of args even once 😭

Think twice before you hit that enter key and keep verified backups

Why don't Unix or Linux developers add safety nets, such as confirmation prompt to the ⁠dd⁠ command by default? That would save lots of headaches 😅

@nixCraft
you're tired and type
rm -rf /temp

but accidentality hit Enter after /

They changed rm

The --preserve-root flag is a safeguard built into modern versions of the rm command to prevent the deletion of the root directory (/). By default, this option is enabled.
Double-check and explicitly set it for added safety.

When --preserve-root is enabled, rm -rf / is blocked

rm: it is dangerous to operate recursively on ‘/’
rm: use — no-preserve-root to override this failsafe
