In the Linux environment, the Vim editor is a powerful text editing tool that is widely used in the work of programmers and system administrators. Vim has multiple working modes, such as normal mode, insert mode, command mode, etc. Each mode has its specific functions and usage. This article will explain the working mode of the Vim editor and attach specific code examples.
1. Normal mode
In Vim, the default mode is normal mode, also called command mode. In this mode, users can enter commands through the keyboard to perform various editing operations, such as moving the cursor, copying and pasting, deleting text, etc. The following are some commonly used operations in normal mode:
- Cursor movement:
- h: Move one character to the left
- j: Move one line down
- k: Move up one line
- l: Move one character to the right
- 0: Move to the beginning of the current line
- $: Move to the end of the current line End of line
- gg: Move to the beginning of the document
- G: Move to the end of the document
- Copy and paste:
- yy: Copy the current line
- p: Paste the copied content
- Delete text:
- x: Delete the character at the cursor
- dd: Delete the current line
2. Insert mode
In normal mode, press the "i" key to enter insert mode, at which time the user can enter text content. Normal mode command operations are not supported in insert mode, and only text can be entered. Press the "Esc" key to return from insert mode to normal mode.
3. Command mode
In normal mode, the user can press the ":" key to enter the command mode. In this mode, various Vim commands can be executed, such as saving files and exiting. Editor etc. The following are some commonly used command mode instructions:
- Save file:
- :w: Save the current file
- :wq: Save and exit
- :q: Exit the editor
- :q!: Force quit the editor (without saving)
- Find text:
- /keyword: Search for keyword
The following is a specific code example that demonstrates how to find the keyword "example" in Vim and replace it with "example":
- Enter the Vim editor and press Press the ":" key to enter the command mode
- Enter "/example" to search for keywords
- Press the "Enter" key to search
- Enter ":s/example/example /g"Replace the keyword with "example"
- Press the "Enter" key to complete the replacement operation
Through the above example, you can see the working mode of the Vim editor and its Specific steps. Proficient in Vim's various modes and operating instructions can improve text editing efficiency and bring convenience to programming and system management.

How to use Docker Desktop? Docker Desktop is a tool for running Docker containers on local machines. The steps to use include: 1. Install Docker Desktop; 2. Start Docker Desktop; 3. Create Docker image (using Dockerfile); 4. Build Docker image (using docker build); 5. Run Docker container (using docker run).

The key differences between CentOS and Ubuntu are: origin (CentOS originates from Red Hat, for enterprises; Ubuntu originates from Debian, for individuals), package management (CentOS uses yum, focusing on stability; Ubuntu uses apt, for high update frequency), support cycle (CentOS provides 10 years of support, Ubuntu provides 5 years of LTS support), community support (CentOS focuses on stability, Ubuntu provides a wide range of tutorials and documents), uses (CentOS is biased towards servers, Ubuntu is suitable for servers and desktops), other differences include installation simplicity (CentOS is thin)

Troubleshooting steps for failed Docker image build: Check Dockerfile syntax and dependency version. Check if the build context contains the required source code and dependencies. View the build log for error details. Use the --target option to build a hierarchical phase to identify failure points. Make sure to use the latest version of Docker engine. Build the image with --t [image-name]:debug mode to debug the problem. Check disk space and make sure it is sufficient. Disable SELinux to prevent interference with the build process. Ask community platforms for help, provide Dockerfiles and build log descriptions for more specific suggestions.

Docker process viewing method: 1. Docker CLI command: docker ps; 2. Systemd CLI command: systemctl status docker; 3. Docker Compose CLI command: docker-compose ps; 4. Process Explorer (Windows); 5. /proc directory (Linux).

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.
