Ubuntu中修改vim設定檔，更方便於c程式設計

1、使用cd /  轉到檔案系統中；

2、cd/etc/vim 切換到vim目錄內；

3、修改檔案許可權 ：  sudo chmod  777 vimrc ，會提示你輸入密碼，輸入密碼即可；

4、vim vimrc   開啟vim檔案，內容基本如下：

" 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、插入設定檔，設定檔如下：
