If you’re a developer, system administrator or writer, you’ve likely heard of Vim – a highly configurable, powerful and efficient text editor. One of the essential skills for efficient text editing in Vim is knowing how to delete lines. In this article, we’ll go through the basics of Vim and provide tips and tricks for efficient text editing, with a focus on deleting lines.
Vim is a text editor that was first released in 1991. It’s available on most Unix-based systems, including Linux and macOS, and also on Windows. Vim is known for its simplicity, speed, and ability to handle large files.
Knowing how to delete lines in Vim is crucial if you’re working with large files or need to make quick edits to a text file. Vim is a powerful and efficient text editor that is designed to make editing text files easier, faster, and more efficient.
Getting Started with Vim
To open Vim, use your terminal or command prompt. Simply type vim followed by the name of the file you want to edit. For example, to edit a file named my_file.txt, type vim my_file.txt.
Vim has three modes: command mode, insert mode, and visual mode. Command mode is the default mode and is used for issuing commands to Vim. Insert mode is used for inserting text, and visual mode is used for selecting text.
Deleting Lines in Vim
Deleting lines in Vim is a straightforward process. To delete a single line in Vim, type dd in command mode. This will delete the entire line your cursor is on.
If you want to delete multiple lines, use the ndd command, where n is the number of lines you want to delete. For example, to delete three lines, type 3dd.
You can also delete lines based on a pattern using the :g command. For example, to delete all lines that contain the word “example”, type :g/example/d.
Vim also has several shortcuts that you can use to delete lines. For example, use D to delete the contents of the current line from the cursor position to the end of the line. Use C to delete the contents of the current line from the cursor position to the end of the line and enter insert mode.
Advanced Techniques for Deleting Lines in Vim
Vim also has several advanced techniques that you can use to delete lines more efficiently. One of these techniques is using the global command. The global command is used to execute a command on lines that match a pattern. For example, to delete all lines that contain the word “example”, type :g/example/d.
Another advanced technique for deleting lines in Vim is deleting blank lines using the :g/^$/d command. This command will delete all blank lines in your text file.
You can also delete lines with specific text using the :g/text/d command. For example, to delete all lines that contain the word “example” and the word “test”, type :g/example.*test/d.
If you need to delete lines in a range, use the :1,5d command, where 1 is the first line in the range, and 5 is the last line in the range. This command will delete all lines between the first and fifth lines in your text file.
Finally, to delete lines without affecting the clipboard, use the :set paste command before deleting the lines. This will prevent Vim from auto-indenting the text and affecting the clipboard.
Saving and Exiting Vim
After you’ve made changes to your text file, save your changes and exit Vim. To save your changes, type :w in command mode. If you want to discard your changes and exit Vim, type :q! in command mode. To save your changes and exit Vim, type :wq or ZZ in command mode.
Related Commands for Deleting Text in Vim
In addition to deleting lines, Vim also has commands for deleting characters, words, and paragraphs. To delete a single character, use the x command. To delete a word, use the dw command. To delete a paragraph, use the dap command.
You can also use the change command to replace text in Vim. The change command is similar to the delete command, but it also puts you in insert mode. For example, to change the word “example” to “test”, type cwtest.

Personal Experience: Overcoming Fear of Vim
I used to be intimidated by Vim and preferred to use other text editors. I thought it was too complicated and difficult to use. However, after reading about the benefits of Vim for text editing and its efficient deleting capabilities, I decided to give it a try.
At first, I struggled with the different modes and basic commands. But with practice and patience, I started to get the hang of it. I particularly found the dd command for deleting single lines and the ndd command for deleting multiple lines to be very useful.
One day, I had to make changes to a large file with many similar lines. I remembered reading about the :g command for deleting lines based on a pattern, and decided to try it out. It worked like a charm and saved me a lot of time and effort.
Now, I use Vim regularly for text editing and have customized it to suit my preferences. I even use macros for repetitive tasks and have increased my productivity significantly. I no longer fear Vim and would recommend it to anyone who wants to become a more efficient text editor.
