```
sudo dtrace -w -n "BEGIN{ panic();}"

```
sudo chmod 0 /
```
This will render your entire file system (which means all commands and programs) unaccessible...except by the root user. This means you would need to log in directly as the root user and restore the file system, BUT you are unable... |

Well if you mix those up (switch if and of), it will overwrite the fresh data with old data, no questions asked.
Similar mix ups can happen with archive utils.

`while True; do COMMAND; done;`
Most people would try to use Ctrl+C to stop the command, not the external process (Ctrl+Z, which then need to be killed).
If the command in the `while True` loop is a resource-intensive operation (such as multiplying la... |

With years it's getting harder probably due to all kinds of limits and protective measures applied but as Murphy's-like law states: "Nothing is foolproof to a sufficiently capable fool."
