- How to detect and solve memory leaks under Linux
- A memory leak refers to the phenomenon that a program applies for memory space but does not release it in time during the running process, causing more and more memory to be occupied, and even causing the system to crash. Memory leak is a common software defect, and it is also a problem that cannot be ignored for Linux systems. So, how to find and fix memory leaks under Linux? What tools can help us detect and analyze memory leaks? This article will introduce you to several commonly used memory leak tools under Linux, allowing you to better manage and optimize memory resources under Linux. Memory leaks can be divided into the following categories: 1. Frequent memory leaks. Code with memory leaks will be executed multiple times, causing a memory leak every time it is executed. 2. I

- Exploring the mysterious world of background operations in Linux
- Let us explore a mysterious world in the Linux operating system - background running. In daily use, we often need to use background running to let tasks execute silently in the background without affecting our current work. So, how to implement background operation in Linux? When thinking about it, you must first consider a question. Why does the background program exit when you directly close the terminal? That is because when you close the terminal directly, the terminal will send a SIGHUP signal to the background tasks started in the current environment, causing the running program to hang. Then just ignore the SIGHUP. The most commonly used command for nohup is [nohup]. From the name, you can tell whether to suspend the running command, close the terminal or log out of an account, and the process will continue to run. At the same time,

- Detailed explanation of Linux device model (6)_Bus
- 1. Overview In the Linux device model, Bus is a special type of device. It is a channel that connects the processor and other devices. In order to facilitate the implementation of the device model, the kernel stipulates that each device in the system must be connected to a Bus. This Bus can be an internal Bus, a virtual Bus, or a PlatformBus. The kernel abstracts the Bus through the structure structbus_type, which is defined in include/linux/device.h. This article will focus on this structure to describe the functions of Bus in the Linux kernel and the related implementation logic. Finally, we will briefly introduce some standard Bus (such as P

- Linux file permission settings: symbolic representation VS numerical representation, which one do you prefer?
- File permission settings are very critical, directly affecting the rights to access, modify, and execute files. Here I will introduce to you two different setting methods as well as my personal experience and opinions on how to set permissions on files in Linux. I hope I can give you some suggestions for your reference. Allow us to start with a warm review of the basics of Linux file permissions. Every file has three basic permissions: read (r), write (w) and execute (x). These permissions can be assigned appropriately to the owner, group and remaining users. Allow me to give you a brief introduction to symbolic notation. When using this method, we need to remember: "r" means read-only, "w" means writable, and "x" means it has execute permission. Besides that, we

- Make your Linux file management easier - upgrade to exa tool
- In Linux systems, file management is a very important operation, but the traditional ls command cannot meet the user's needs for file list display. At this time, a more powerful and easy-to-use tool is needed. Today, we will introduce a tool called exa, which can make your Linux file management simpler and more efficient. Introduction to the exa command exa is a command line tool that can list directories and files in the specified path (if not specified, the current directory). This may sound familiar because that's what the ls command does. exa is seen as a modern replacement for the ancient ls command from the old days of UNIX. As claimed, it has more features and better default behavior than the ls command

- Examples to explain the creation of hard links and soft links in Linux systems
- There are two types of Linux links, one is called a hard link and the other is called a symbolic link. By default, the ln command generates hard links. The difference between hard links and soft links fundamentally starts with the inode node. The following are examples of creating hard links and soft links in Linux systems to see the differences between the two types of links in Linux. First of all, we must understand that in the Linux system, the kernel allocates an Inode (index node) to each newly created file, and each file has a unique inode number. File attributes are stored in the index node. When accessing the file, the index node is copied to the memory, thereby achieving fast access to the file. A link is a

- With one machine in hand, Linux commands are worry-free - master the skills of using multiple commands in the terminal
- As Linux users, we often need to execute multiple commands at the same time in the terminal to improve efficiency and convenience. For beginners, however, the process can be very tedious and confusing. Today, we will introduce you to some techniques for using multiple commands in the Linux terminal, so that you can handle various tasks easily and happily. Running two or more commands in one line can save a lot of time and increase efficiency in Linux. In Linux, there are three ways to run multiple commands in one line:;Command1;Command2 first runs Command1, then runs Command2&&Command1&&Command2. When Command1 runs successfully and ends, then
