How to Delete Multiple Lines in Vim
Want to delete multiple lines or all lines or all empty lines in Vim? Here are a few tips to know about line deletion in Vim.
We all make mistakes. Making mistakes is human. Improving upon it is also important.
If you make a mistake in Vim, you can delete a word by using dw in normal mode. You type dd and it deletes the current line.
If you want to delete multiple lines in Vim, you can use the same dd Vim command by adding the number of lines to it.
So, 10dd will delete 10 lines from the bottom of the cursor (including the line that the cursor is at).
Let's take a detailed look at how you can delete one or more lines in an editor that is famous for its efficiency.
Delete single line
Below are the steps on deleting a single line of text in Vim:
- Enter the Normal mode by pressing the Escape (Esc) key
- Make sure that your cursor is on the line that you want to delete.
- Quickly press
dd
That will delete the entire line that your cursor is on.
As you can see in the gif, I am on the first line and running the dd command deleted only the first line.
Specify number of lines to delete
Before you use the dd command to delete a line, you can specify a number before it to delete several lines at once in Vim.
Below is the syntax:
:[num]ddWhen you specify number in place of num, Vim will start deleting lines. You can think of this as Vim is performing the dd command for num times.
As evident from the gif, I ran the command 12dd (it appears in the bottom-right corner) and it deleted the block of 12 lines.
Specify a range of lines to delete
Instead of specifying how many lines to delete from the current line to bottom, you can just tell Vim from which line it should start deleting and up to which line.
It will work better if you have enabled line number display in Vim.
Below is the syntax to delete a range of lines:
:[begin],[end]dLet's break this syntax down...
:(colon) indicates that it is a Vim command.begintells Vim what line to begin fromendtells Vim what the last line to delete isdthe delete command in Vim
Moreover, below are the characters used to specify the range (used for 'begin' and 'end):
.(current line)$(last line in file)%(all lines)
To learn from a few examples, let's take a look at them.
:10,45d- Delete from 10th line to 45th line:.,$d- Delete from current line till the last line:.,1d- Delete from current line to beginning of the file:dgg- Delete from current line to beginning of the file
As you can see in this gif, even though I am on line 31, and I typed :10,29d and it deleted lines from 10 to 29.
Delete all lines
As mentioned earlier, the % symbol is used to specify the range from beginning to the end of file, essentially all lines.
This means, to delete all lines of a file in Vim, you need to use :%d command.
Delete lines that match a certain pattern
Apart from all these Vim wizardry, did you know that you could delete lines that matched a particular pattern?
Well, you can, and here is the syntax.
:g/PATTERN/dTo do the opposite of this, deleting the lines that do not match the specified pattern, you can use the syntax specified down below.
:g!/PATTERN/dBreaking this down, we get the following elements:
g- search globally (i.e. the entire file)!- reverse matchPATTERN- the pattern to matchd- delete command
If you run the following command in Vim, it will remove all the lines that have "extern crate" pattern in the line.
:g/extern\ crate/d
Delete all empty lines
To delete empty lines, it is necessary to use regex for pattern matching. Below is the command for perform deletion of empty lines:
:g/^$/dIn regex, the ^$ pattern means any line that starts with a newline, essentially an empty line.
