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-

raid Introduction: RAID (Redundant array of inexpensive Disks) is called a redundant array of inexpensive disks. The basic principle of RAID is to put multiple inexpensive small disks RAID level description; generally used RAID class, Are RAID 0, RAID1, RAID 2, RAID 3, RAID 4, and RAID 5, plus two-in-one raid 0+1 or RAID 1+

, we only use * (p + 4) to view the content, but it does not change the point of P. P still refers to the first address, so the printed string starts with the first character.If we add the following two sentences to the Code:Printf ("% C \ n", * P ++ );Printf ("% s \ n", P );The first execution result is to print the first character 'B', and then P moves back one character. Therefore, the following print string starts with the second character and returns rucelee.CONCLUSION: (* P + 4) This metho

RAID (Redundant Array of Independent Disk Independent Redundant Disk Array) technology was proposed by the University of California at Berkeley in 1987, initially to combine small cheap disks to replace large expensive disks, at the same time, we hope that when the disk fails, data access will not be damaged and a certain level of data protection technology will be de

This presentation is a simple file upload and download, in theory the ID should be stored as the field of the action table after uploading, here only the presentation file is uploaded to the document object

In the previous section, the flowchart we drew, remember? Judging the part we will, the difference cycle, below I will introduce three kinds of commonly used loops.Loop structure while loop (when looping, at least my C language teacher calls it)Let's introduce the syntax, as follows while (conditional expression) { // Here is the loop body, when the above condition expression is true, the loop body is executed, otherwise exits }While followed by a conditional expression, the loop is executed
Python 0-basic entry-5 string formatting and built-in functions of sequences first of all, let's briefly talk about tuples. tuples joke about sequences with shackles, this is because tuples do not perform a series of operations on their elements as they do in sequence. Once a tuples are defined, the elements in the tuples cannot be changed at will.
Definition of tuples: Names of tuples = (,,,,,,)
