Whether you are a beginner or an advanced user, this guide will help you master line numbering in Vim and improve your coding productivity.
Enabling Line Numbers in Vim
Line numbers are a crucial tool for navigating a file and keeping track of your code. In Vim, enabling line numbers is a straightforward process that can significantly enhance your workflow. The following instructions are necessary:
- Open Vim in the terminal by typing
vim
and pressing Enter. - Press the
Esc
key to switch to command mode. - Type
:set number
and press Enter. - On the editor’s left side, line numbers will appear.
The :set number
command tells Vim to display line numbers. You can turn off line numbers by typing :set nonumber
in command mode.
It’s worth noting that you can also enable line numbers in Vim for all files by adding the set number
command to your Vimrc file. As a result, whenever you open Vim, line numbers will always be enabled.

III. Locating Line numbers in Vim Is Not Effective
Disable Line Numbers in Vim
Even though line numbers can be a useful tool in Vim, there may be times when you want to turn them off. The presence of line numbers, for instance, can make it challenging to read and navigate through a file that has a lot of lines. We’ll walk you through the procedures in this section to turn off line numbers in Vim.
Simply remove the command from the Vimrc file to turn off line numbers in Vim. Follow the instructions listed below to accomplish this:
- Open the Vimrc file by typing
vim ~/.vimrc
in your terminal. - Locate the line of code that reads
set number
. - Remove the line of code by typing
dd
. - Save the changes and exit the file by typing
:wq
.
Alternatively, you can disable line numbers temporarily by using the :set nonumber
command in command mode. Follow the instructions listed below to accomplish this:
- Vim files should be opened.
- Enter command mode by pressing the
Esc
key. - Type
:set nonumber
and press Enter. - On the editor’s left side, line numbers will stop appearing.

You can quickly eliminate line numbers in Vim to suit your preferences and needs by using either of these methods.
Customizing Line Numbers in Vim
Your productivity can be increased and code can be easier to navigate by customizing the appearance of line numbers. To change the line numbers, follow the following steps:
- Open Vim in the terminal by typing
vim
and pressing Enter. - Press the
Esc
key to switch to command mode. - Type
:set number
and press Enter to display line numbers. - To change the color of the line numbers, type
:highlight LineNr ctermfg=<color-code>
and press Enter. For example, to change the line number color to blue, you can use:highlight LineNr ctermfg=blue
. - To change the width of the line numbers, type
:set numberwidth=<value>
and press Enter. For example, to set the width to 3, you can use:set numberwidth=3
. - To change the format of the line numbers, type
:set formatoptions+=<option>
and press Enter. For example, to display line numbers with leading zeros, you can use:set formatoptions+=l
. - You can also customize the background color of the line numbers by using the
:highlight
command. For example, to set the background color to gray, you can use:highlight LineNr ctermbg=gray
.
In the example above, the highlight
command is used to change the color of the line numbers to white. You can use any color code you like by changing the ctermfg
value.

You can modify the appearance of line numbers in Vim to suit your preferences and needs by following these steps. To find what works best for you, experiment with various hues, widths, and formats.
Setting Line Numbers in Vimrc
The configuration file known as the Vimrc is used by Vim. You can set Vim to automatically display line numbers by adding a straightforward command to this file. In Vimrc, line numbers can be set in the following manner:
- Open the terminal and type
vim ~/.vimrc
and press Enter. - To enable line numbers, scroll down to the bottom of the file and add the following line of code:
set number, which
The line numbers will appear in the left-hand column of the Vim editor as a result.
- By adding the following line of code, you can also modify the line numbers to begin at a particular value:
[start_value] set number
Replace [start_value]
with the number at which you want the line numbers to start.
- Save the file by pressing
Esc
and typing:wq
and press Enter.

After finishing these steps, Vim will display line numbers in the editor’s left-hand column for all files and sessions.
Other Line Numbering Options in Vim
Vim offers a number of additional line numbering options in addition to the standard line numbering option that can be useful in various circumstances.
Relative Line Numbering
In relation to the current line, relative line numbering displays the line numbers. For instance, if the current line is line 10, the line below it will be -1, and so forth. This can be useful for quickly navigating through a file and figuring out where lines are in relation.
Follow these instructions to enable relative line numbering in Vim:
- Open Vim in the terminal by typing
vim
and pressing Enter. - Press the
Esc
key to switch to command mode. - Type
:set relativenumber
and press Enter. - The line numbers will now be compared to the line at hand.

Hybrid Line Numbering
Combining absolute and relative line numbering is known as hybrid line numbering. The current line has an absolute line number, and the other lines have comparisons to the current line. This can be useful for locating lines and navigating a file quickly.
Follow these steps to make hybrid line numbering possible in Vim:
- Open Vim in the terminal by typing
vim
and pressing Enter. - Press the
Esc
key to switch to command mode. - Type
:set relativenumber number
and press Enter. - The line numbers will now be displayed, with the current line having an absolute line number and the other lines showing up in relation to the previous line.

Users can alter line numbers’ appearance and behavior to suit their preferences thanks to their customizable relative and hybrid line numbering options.
VII. How to Fix Line Number Problems in Vim
Troubleshooting Line Numbers in Vim
Even though Vim is an effective tool for displaying line numbers in the editor, occasionally problems can arise. In this section, we’ll go over some typical problems that users might run into when using line numbers in Vim and offer solutions and troubleshooting advice for each problem.
Line Number Overlap
In Vim, line numbers frequently show up on top of the file’s content, making it challenging to read. When using a unique color scheme, this might occur. To fix this issue, you can try changing the color scheme to the default one by typing :colorscheme default
in command mode.
Incorrect Numbering
Incorrect numbering, where line numbers do not accurately match the actual lines in the file, is another frequent problem with line numbers in Vim. This may be brought on by a number of things, such as plugin conflicts or hidden characters. Try disabling any plugins you’ve installed to see if that fixes this problem. You can try reformatting the file or removing any hidden characters if this does not resolve the issue.
Other Issues
Users may encounter other issues when working with line numbers in Vim in addition to the ones mentioned above. Some of these problems might call for more complex troubleshooting, like checking your Vim configuration or resetting your preferences. If you run into any other problems with line numbers in Vim, try looking in online forums and communities for solutions or look into the Vim documentation for more details.
