1. 创建~/.vimrc文件

2. 写入如下内容：

map <F4> ms:call TitleDet()<cr>'s

function AddTitle()
    call append(0,"##############################################")
    call append(1,"#")
    call append(2,"# Author: WANG Zizhe  - 344593137@qq.com")
    call append(3,"#")
    call append(4,"# QQ : 344593137")
    call append(5,"#")
    call append(6,"# Last modified: ".strftime("%Y-%m-%d %H:%M"))
    call append(7,"#")
    call append(8,"# Filename: ".expand("%:t"))
    call append(9,"##############################################")
    call append(10,"# Description: ")
    call append(11,"#!/bin/bash")
    echohl WarningMsg | echo "Successful in adding the copyright." | echohl None

endfunction

function UpdateTitle()

    normal m'
    execute '/# *Last modified:/s@:.*$@\=strftime(":\t%Y-%m-%d %H:%M")@'
    normal ''
    normal mk
    execute '/# *Filename:/s@:.*$@\=":\t\t".expand("%:t")@'
    execute "noh"
    normal 'k
    echohl WarningMsg | echo "Successful in updating the copy right." | echohl None

endfunction

function TitleDet()

    let n=1
    while n < 10
        let line = getline(n)
        if line =~ '^\#\s*\S*Last\smodified:\S*.*$'
            call UpdateTitle()
            return
        endif
        let n = n + 1
    endwhile
    call AddTitle()
endfunction
