In programmer jargon, especially in Unix jargon,/dev/null is known as a bit bucket, or bit-bucket, or a black-hole. This empty device is often used to discard unwanted output streams, or as an empty fi

If you want random data in a Linux/Unix type OS, the standard way to do so is to use/dev/random or/dev/urandom. these devices are special files. they can be read like normal files and the read data is generated via multiple sources of entropy in the system which provide the randomness./Dev/random will block after the entropy pool is exhausted. It will remain bloc
