我自己的vim配置：

set number    "显示行号"
set tabstop=4    "Tab键的宽度"
set softtabstop=4
set shiftwidth=4
set mouse=a
syntax on    "语法高亮"
set autoindent
set showcmd  "输入的命令显示出来，看的清楚些" 
set cindent
set nobackup

autocmd BufNewFile *.cpp,*.[ch],*.sh,*.java exec ":call SetTitle()" 
"定义函数SetTitle，自动插入文件头"
func SetTitle() 
    "如果文件类型为.sh文件" 
    if &filetype == 'sh' 
        call setline(1,"\#########################################################################") 
        call append(line("."), "\# File Name    : ".expand("%")) 
    call append(line(".")+1, "\# Description  : ")  
        call append(line(".")+2, "\# Author       : Qreal") 
        call append(line(".")+3, "\# Mail         : 1336529610@qq.com") 
        call append(line(".")+4, "\# Created Time : ".strftime("%Y-%m-%d %H:%M:%S"))   
        call append(line(".")+5, "\# Last modified: ".strftime("%Y-%m-%d %H:%M:%s"))  
        call append(line(".")+6, "\#########################################################################") 
        call append(line(".")+7, "\#!/bin/bash") 
        call append(line(".")+8, "") 
    else 
        call setline(1, "/*************************************************************************") 
        call append(line("."), "    > File Name    : ".expand("%")) 
        call append(line(".")+1, "    > Description  : ")  
        call append(line(".")+2, "    > Author       : Qreal") 
        call append(line(".")+3, "    > Mail         : 1336529610@qq.com ") 
        call append(line(".")+4, "    > Created Time : ".strftime("%Y-%m-%d %X"))   
        call append(line(".")+5, "    > Last modified: ".strftime("%Y-%m-%d %X"))  
        call append(line(".")+6, " ************************************************************************/") 
        call append(line(".")+7, "")
    endif
    if &filetype == 'cpp'
        call append(line(".")+8, "#include<iostream>")
        call append(line(".")+9, "using namespace std;")
        call append(line(".")+10, "")
    endif
    if &filetype == 'c'
        call append(line(".")+8, "#include<stdio.h>")
        call append(line(".")+9, "")
    endif
    "新建文件后，自动定位到文件末尾"
    autocmd BufNewFile * normal G
endfunc

"""""""""""""""""""""""""""""""""""""""""  
"实现上面函数中的，Last modified功能"  
"""""""""""""""""""""""""""""""""""""""""  
autocmd BufWrite,BufWritePre,FileWritePre  *.c    ks|call LastModified()|'s    
func LastModified()  
    if line("$") > 20  
        let l = 20  
    else   
        let l = line("$")  
    endif  
    exe "1,".l."g/Last modified: /s/Last modified: .*/Last modified:".  
            \strftime(" %Y-%m-%d %X" ) . "/e"  
endfunc

在网上搜索了很多内容，参考了论坛上的一些代码，给配置了一个，用着觉得还不错。
