Properly visualizing a file can help us debugging scripts, code or configuration files, in this article, I will explain how to configure VI with this objective.
First, we check the available themes:
ls -la /usr/local/share/vim/vim90/colors/
total 247
drwxr-xr-x 4 root wheel 30 Jul 7 22:24 .
drwxr-xr-x 19 root wheel 37 Jul 7 22:24 ..
-rw-r--r-- 1 root wheel 4694 Jul 2 09:48 README.txt

drwxr-xr-x 2 root wheel 3 Jul 7 22:24 tools
-rw-r--r-- 1 root wheel 20093 Jul 2 09:48 torte.vim
-rw-r--r-- 1 root wheel 40572 Jul 2 09:48 wildcharm.vim
-rw-r--r-- 1 root wheel 23986 Jul 2 09:48 zaibatsu.vim
-rw-r--r-- 1 root wheel 19519 Jul 2 09:48 zellner.vim
We must instruct to load the theme. I am showing the entire configuration as it is valid in FreeBSD and can be very useful:
vi .vimrc
set nocompatible
set mouse=
set backspace=indent,eol,start
set termguicolors
set t_Co=256
syntax on
colorscheme torte
We can see how the scripts look like:
