Deeply understand the working mode of Vim under Linux

In the Linux operating system, Vim is a very powerful text editor and is widely used by programmers, system administrators and Linux user groups. Vim has multiple working modes, including normal mode, insert mode, command line mode, etc. Each mode has different functions and operation methods. In this article, we will provide an in-depth understanding of the working modes of Vim under Linux and provide specific code examples to help readers better master these modes.

1. Normal mode

In Vim, when the user opens a file, it enters the normal mode by default. In normal mode, users can browse file contents, move the cursor, copy and paste text, and other operations. In addition, users can also switch Vim to other modes through commands, such as insert mode and command line mode.

The following is a specific operation example in normal mode:

  1. Move the cursor: Use the direction keys or shortcut keys (h, j, k, l) to move the cursor.
  2. Copy text: Press "yy" to copy the current line, and press "p" to paste the copied content.
  3. Search text: Press "/" to search for specified content in the current file.
  4. Delete text: Press "x" to delete the character at the cursor position.

2. Insert mode

In Vim, the user can enter the insert mode by pressing the "i" or "Insert" key. At this time, the user can enter the insert mode as in a normal editor. Enter text as usual. In insert mode, the user can exit insert mode and return to normal mode through the "Esc" key.

The following is a specific operation example in insert mode:

  1. Insert text: Press "i" to enter insert mode and enter text at the cursor.
  2. Save the file: Press ":w" to save the file, and press ":q" to exit Vim.

3. Command line mode

In Vim, the user can enter the command line mode by pressing the ":" key. The user can execute various commands in this mode. Such as saving files, exiting Vim, etc.

The following is a specific operation example in command line mode:

  1. Save the file: Enter ":w" in the command line to save the file.
  2. Exit Vim: Enter ":q" in the command line to exit Vim.
  3. Force saving: Enter ":w!" in the command line to force save the file.

To sum up, to deeply understand the working mode of Vim under Linux, you need to be familiar with the normal mode, insert mode and command line mode, and master the switching methods and specific operations between them. Through the code examples provided in this article, I believe readers will have a clearer understanding of Vim's working mode, thereby improving their text editing capabilities in the Linux environment.

How Debian improves Hadoop data processing speedHow Debian improves Hadoop data processing speedApr 13, 2025 am 11:54 AM

This article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file
