Imagine your file is penned up in a steel chamber, with a tiny amount of radioactive substance. In the course of your typing scat there is a probability that a small radioactive burst causes a bit in memory to flip, but also equal probability that no bits flip. If such a bit flips, the counter tube in a Geiger Counter discharges and releases a hammer that shatters a small flask of sudo rm -f. One would say that the file exists if no atom has decayed. The psi-function of the entire system would express this by having your file in the saved and deleted state!
scat $FILENAME
That's hard to say
Just add scat to your PATH.
