Initial Settings : Vim Settings2019/09/25
 
There are many cases to use text editor on CUI terminal, so it's more convenient to install editors with advanced features like Vim.
[1] Install Vim in this example.
[root@dlp ~]#
dnf -y install vim-enhanced

[2] Set command alias for your own environment.
But for users that has UID 201 or higher, Alias is already set by [/etc/profile.d/vim.sh] file that is included in [vim-enhanced] package.
[root@dlp ~]#
vi ~/.bashrc
# add alias to the end

alias vi='vim'
# apply changes

[root@dlp ~]#
source ~/.bashrc
[3] Configure Vim for your own environment. (common settings for all users are in [/etc/vimrc])
[root@dlp ~]#
vi ~/.vimrc
