My Vim configuration (with comments)

My Vim configuration (with annotations) is relatively simple and practical, and will be updated continuously in the future based on the function addition.

If you need to copy the following content to the. vimrc file in the user's home directory, restart vim. For example, if the current Linux user name is Andy, the default home directory is/home/Andy. You can also use CD ~ in the command line ~ Command to enter; 2. the. vimrc file is a hidden file, which can be viewed through the LS-l command in the home directory.
