About/dev/null and/dev/zero

Using/dev/null Think of/dev/null as a "black hole". It is very equivalent to a write-only file. All content written to it is lost forever. And trying to read content from it is nothing.

Sinsing interpretation of/dev/null and/dev/zero

In a Unix-like system,/dev/null is called an empty device, which is a special device file that discards everything written to it, but he reports that the write succeeds and reads it immediately to get an EOF. 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

Random number file/dev/random/dev/urandom in Linux

Random numbers in Linux can be generated from two special files, one/dev/urandom. The other is/dev/random. the principle of generating random numbers is to use the current system's entropy pool to calculate a fixed number of random bits , and then return these bits as a byte stream. entropy Pool is the current system of environmental noise , entropy refers to a system of chaos, system noise can be evaluated

/Dev/random vs/dev/urandom

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
