What command can you use to enable line numbering in Vim?

by EITCA Academy / Saturday, 05 August 2023 / Published in Cybersecurity, EITC/IS/LSA Linux System Administration, Advanced sysadmin in Linux, Vim basics, Examination review

To enable line numbering in Vim, you can make use of the ":set number" command. Vim is a widely used text editor in the Linux environment, known for its versatility and powerful features. By enabling line numbering, you can easily navigate through your code or text files, making it easier to reference specific lines and locate errors or issues.

The ":set number" command is a Vim command that sets the "number" option to enable line numbering. This option displays line numbers on the left side of the Vim editor window. When enabled, each line in the file will be prefixed with its corresponding line number.

To enable line numbering, follow these steps:

1. Open the file in Vim by running the "vim" command followed by the file name. For example, to open a file named "example.txt", you would run:

vim example.txt

2. Once the file is open in Vim, enter the command mode by pressing the ":" key.

3. In command mode, type "set number" (without quotes) and press Enter. This command sets the "number" option to enable line numbering.

:set number

4. After executing the command, you will see line numbers displayed on the left side of the Vim editor window.

Here is an example to illustrate the process:

Suppose you have a file named "my_script.py" containing the following code:

def hello_world():
    print("Hello, world!")

hello_world()

To enable line numbering for this file in Vim, you would follow these steps:

1. Open the file in Vim:

vim my_script.py

2. Enter command mode by pressing ":".

3. Type "set number" and press Enter:

:set number

4. Line numbering will now be enabled, and you will see the line numbers displayed on the left side of the Vim editor window:

1 def hello_world():
2     print("Hello, world!")
3 
4 hello_world()

By enabling line numbering, you can easily reference specific lines in your code or text files, improving your productivity and efficiency while working with Vim.

To enable line numbering in Vim, use the ":set number" command. This command sets the "number" option and displays line numbers on the left side of the Vim editor window. Line numbering can be useful for navigating and referencing specific lines in your code or text files.
