To reload the .vimrc file without restarting Vim on Linux or Unix, you can use the :source command in Vim.
To reload the .vimrc file, open Vim and enter the following command:
:source ~/.vimrc
This will reload the .vimrc file and apply any changes to the current Vim session.
You can also create a custom command in your .vimrc file to reload the .vimrc file. For example, you can add the following line to your .vimrc file:
command! ReloadVimrc source ~/.vimrc
This will create a custom command ReloadVimrc that you can use to reload the .vimrc file. To use the command, enter the following in Vim:
:ReloadVimrc
