我在vimrc中添加了如下内容。执行了source /etc/vimrc。但是没有效果

auto BufNewFile *.py,*.sh, exec ":call SetTitle()"

let $author_name = ”Tianlianhao“

let $author_emal ="214520626@qq.com"

func SetTile()

if &filetype == 'sh'

call setline(1,"\#####################################################")

call append (line("."),"\#File Nme:".expand("%"))

call append(line(".")+1,"\#Author:".$author_name)

call append(line(".")+2,"\#mail:".$author_email)

call append(line(".")+3,"\#Created Time:".strftime("%c"))

call append(line(".")+4,"\#==============================================")

call append(line(".")+5,"\#!/bin/bash")

call append(line(".")+6,"")

else

call setline(1,"\#######################################################")

call append(line("."),"#\#File Name:".expand("%"))

call append(line(".")+1,"\#Author:".$author_name)

call append(line(".")+2,"\#mail:".$author_email)

call append(line(".")+3,"\Created Time:".Strftime("%c"))

call append(line(".")+4,"\#================================================")

call append(line(".")+5,"\#!/usr/bin/python")

call append(line)("."+6,""))
