1./dev/null/Dev/null is equivalent to a black hole, and the data written into it will be lost forever. No data can be read from it.In general,/dev/null is used to block shell error output../Myshell. Sh 2>/dev/nullThe preceding command is used to execute a custom shell. If an error message is displayed during execution,

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

There are two installation failures that are caused by dependent library version issues:1, because the source needs to be updated, the following actions:Libssl-dev: dependent: libssl0.9.8 (= 0.9.8o-1ubuntu4) But 0.9.8o-1ubuntu4.4 is about to be installed workaroundGo to Settings, Update Manager, System Management, Systems Manager, select the Updates tab in the pop-up Software Sources dialog box, and check the four check boxes under Ubuntu update to tu

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

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

Linux is a file-based system, and all hardware, such as software, will have a corresponding file representation under the directory. For Dev This directory, we know the file below it, which represents the Linux device. In Windows systems, devices are well understood, like hard disks, which refer to real hardware. Under Linux for file systems, there are files associated with these devices. Access to them can be put into the actual hardware, think or Li
