Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,

I. The role of "#if 0/#if 1 ... #endif" 1 code is defined in a number of debug version codes, this time the code is completely ignored by the compiler. If you want code to take effect, just change #if 0 to #if 1. 2 #if 0 There i

The RAND function requires a system-supplied seed to generate a sequence of pseudo-random numbers before generating a random number, and Rand produces a series of random numbers based on the value of the seed. If the seed provided by the system does not change, the sequence of pseudo-random numbers generated by each call to the RAND function is the same. Srand (unsigned seed) alters the seed value provided by the system through the parameter seed, which allows the sequence of pseudo-random numbe

Os._exit () and Sys.exit ()Os._exit () vs Sys.exit ()OverviewPython's program has two exit methods: Os._exit (), Sys.exit (). This article describes the differences and choices between the two approaches.Os._exit () will terminate the Python program directly, and all subsequent code will not continue to execute.Sys.exit () throws an exception: Systemexit, if the exception is not captured, the Python interpreter exits. If there is code to catch this exception, the code will still execute. Catchin

What is a programming language?To give an example:If we do not speak English, and a foreigner who can not speak Chinese, how to do? Find a translator.Computers only know the machine language consisting of 0 and 1. Use 0 and 1 to tell the computer to work very tired, human language easy to understand, learning fast, hig

This article describes the PHP greedy algorithm to solve the 0-1 knapsack problem method. Share to everyone for your reference. The specific analysis is as follows: The greedy algorithm solves 0-1 knapsack problem, and the global optimal solution is obtained by local optimal solution. More flexible than dynamic planni

The process of doing a project often has a random selection process. This note mainly gives two methods of randomly generating n different random numbers, and then simply introduces the function Srand,rand and time used in the random numbers in C + +. In the end, a simple example is given, which is to randomly select K images from a folder containing n images to be stored in another folder.A: A method of generating n different random numbers#include II: Introduction to Srand,rand and time functi

It's all the same, it's quitting, just returning this 0 and 1 is the error or the correct code to return to the operating system.Exit 1 refers to the return value that the script runs to indicate success or failure, and the reason for the failure.Exit 0 indicates success, exit 1
