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,1: single-user mode,2: Multi-

One, object-oriented characteristics Three basic features: encapsulation, inheritance, and polymorphism. 1, packagingThe core idea of object-oriented programming this is to encapsulate the data with the operations of the data. By abstraction, that is, extracting common properties from concrete instances to form general concepts, such as class concepts. 2. InheritInheritance embodies an advanced programming pattern. Subclasses can inherit the properties and functionality of the parent class, whic

There are many formulas for calculating pi pai in history, in which Gregory and Leibniz found the following formula: Pai = 4* (1-1/3+1/5-1/7 ...) The formula is simple and graceful, but in a bad way, it converges too slowly. If we rounded to keep its two decimal digits, then: Cumulative 1 items and are: 4.00 Cumulative 2 items and are: 2.67 Cumulative 3 ite
