Ubuntu中修改vim配置文件，更方便于c程序设计
1、使用cd / 转到文件系统中；
2、cd/etc/vim 切换到vim目录内；
3、修改文件权限 ： sudo chmod 777 vimrc ，会提示你输入密码，输入密码即可；
4、vim vimrc 打开vim文件，内容基本如下：
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/debian.vim) and sourced by the call to :runtime
" you can find below. If you wish to change any of those settings, you should
" do it in this file (/etc/vim/vimrc), since debian.vim will be overwritten
" everytime an upgrade of the vim packages is performed. It is recommended to
" make changes after sourcing debian.vim since it alters the value of the
" 'compatible' option.
" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.
runtime! debian.vim
" Uncomment the next line to make Vim more Vi-compatible
" NOTE: debian.vim sets 'nocompatible'. Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
"set compatible
" Vim5 and later versions support syntax highlighting. Uncommenting the
" following enables syntax highlighting by default.
if has("syntax")
syntax on
endif
" If using a dark background within the editing area and syntax highlighting
" turn on this option as well
"set background=dark
" Uncomment the following to have Vim jump to the last position when
" reopening a file
"if has("autocmd")
" au BufReadPost * if line("'/"") > 1 && line("'/"") <= line("$") | exe "normal! g'/"" | endif
"endif
" Uncomment the following to have Vim load indentation rules and plugins
" according to the detected filetype.
"if has("autocmd")
" filetype plugin indent on
"endif
" The following are commented out as they cause vim to behave a lot
" differently from regular Vi. They are highly recommended though.
"set showcmd " Show (partial) command in status line.
"set showmatch " Show matching brackets.
"set ignorecase " Do case insensitive matching
"set smartcase " Do smart case matching
"set incsearch " Incremental search
"set autowrite " Automatically save before commands like :next and :make
"set hidden " Hide buffers when they are abandoned
"set mouse=a " Enable mouse usage (all modes)
" Source a global configuration file if available
if filereadable("/etc/vim/vimrc.local")
source /etc/vim/vimrc.local
endif
5、插入配置文件，配置文件如下：

""""""""""""""""""""""""""""""""""""""
"开启语法高亮

syntax on

:set nocompatible
其插入位置在倒数第5行，为了和以前内容区别，插入内容前后多打些空格

7、保存。保存方法：按ESC键后，输入：wq，回车，即可。
8、至此，配置文件修改成功。
