Copy and paste programming in Linux VI editor

In Linux systems, the VI editor is a powerful text editing tool. Not only can it edit text, it can also perform copy and paste operations, allowing programmers to write code more efficiently. This article will introduce in detail how to copy and paste operations in the VI editor and provide corresponding source code examples.

The copy operation copies the selected content to the clipboard so that it can be pasted later. In the VI editor, we can use the following steps to perform a copy operation:

1. First, go into the VI editor and open the file you want to edit.

2. Use the cursor keys to move to the starting position where you want to copy.

3. Press vthe key to enter visual mode. At this point, you will see the text highlighted.

4. Use the cursor keys to move to where you want the copy to end.

5. Press ythe key to copy the selected text to the clipboard.

Now you have successfully copied the selected text to the clipboard. Next, we will introduce how to perform the paste operation.

The paste operation inserts the contents of the clipboard into the text at a specified location. In the VI editor, we can use the following steps to perform the paste operation:

1. Use the cursor keys to move to where you want to paste.

2. Press pthe key to paste the contents of the clipboard after the cursor position.

Now, you have successfully pasted the contents of the clipboard to the specified location.

Here is a simple example that demonstrates how to copy and paste in the VI editor:

Let's say we have a example.txtfile called with the following content:

Hello, World!

We want to copy this line of text twice and paste it at the end of the file. Following the above steps, we can do the following:
