vim配置文件备份

1、/usr/share/vim/vimrc 的内容如下 ：

set showmatch
set incsearch
set mouse=a
set cindent
set hlsearch
set tabstop=4
set softtabstop=4
set shiftwidth=4
set nu
set tags=tags;
set autochdir

let Tlist_Show_One_File = 1			" -------只允许taglist显示一个文件的信息  
let Tlist_Exit_OnlyWindow = 1			" ---------当显示taglist信息的窗口是最后一个时，退出vim  
let Tlist_Process_File_Always = 1		" -----时时更新taglist  
let Tlist_Auto_Open = 1

"cscope插件热键
nmap cs :cs find s <C-R>=expand("<cword>")<CR><CR> 
nmap cg :cs find g <C-R>=expand("<cword>")<CR><CR> 
nmap cc :cs find c <C-R>=expand("<cword>")<CR><CR> 
nmap cd :cs find d <C-R>=expand("<cword>")<CR><CR> 
nmap ct :cs find t <C-R>=expand("<cword>")<CR><CR>

nmap cf :cs find f <C-R>=expand("<cfile>")<CR><CR> 
nmap ci :cs find i ^<C-R>=expand("<cfile>")<CR><CR>

" add any cscope database in current directory
if has("cscope")
	set cscopetag
	set csto=0
	if filereadable("cscope.out") " 若当前目录下存在cscope数据库，添加该数据库到vim
		cs add cscope.out
	elseif $CSCOPE_DB != "" " 否则只要环境变量CSCOPE_DB不为空，则添加其指定的数据库到vim
		cs add $CSCOPE_DB
	endif
endif

2、/bin/cscope.sh 的内容如下：（在源码要目录下执行“source /bin/cscope.sh”即可生成cscope需要的索引，参考：cscope的快速初始化和使用技巧）

#!/bin/bash

DIR=`pwd`
update=1
change=0
while getopts "d:uc" opt;
do
    case $opt in
        d)
            DIR=$OPTARG
			;;
		u)
			update=1
			;;
		c)
			change=1
			;;
		?)
			echo "invaild option!"
			exit 1
	esac
done

cd ${DIR}

if [ 1 -eq ${change} ]; then
	echo "change project cscope database!"
	res=$(find ${DIR} -name cscope.out)
	if [ "x"${res} = "x" ]; then
		echo "Not found cscope database, generate cscope database!"
		find ${DIR} -name "*.[h|c|cc|cpp|hh]" > cscope.files
		cscope -bkq -i cscope.files 
		#ctags -R *
		export CSCOPE_DB=${DIR}/cscope.out
	else
		echo "Found cscope database:${res}, just change CSCOPE_DB env!"
		export CSCOPE_DB=${res}
	fi
elif [ 1 -eq ${update} ]; then
	echo "udpate project cscope database!"
	find ${DIR} -name "*.[h|c|cc|cpp|hh]" > cscope.files
	cscope -bkq -i cscope.files
	#ctags -R *
	export CSCOPE_DB=${DIR}/cscope.out
fi

echo CSCOPE_DB_PATH=${CSCOPE_DB}
