@Ram chandra Giri: I recall back from college the Linux distro Suicide Linux, where every wrong command was interpreted as the following:
rm -rf /
I assume someone here knows exactly what the command does. 😂😎😂
We use to joke around that we would replace the campus' Linux machines OS with this, and let the madness unfold. But our manager said while funny, he might get thrown under the bus, and then he'd fire us.
