首先谢谢大家！
数据格式如下，有三万多行，现在的问题是：
如何从庞大的数据中找出Total不等于0的酒店，然后把ARRIVALS这一行的酒店名称提取出来。老婆每个月都要处理这样的数据，工作得很辛苦，请大家帮帮忙，写个批处理，鄙人在这里鞠躬了。

ARRIVALS: 10005 - Five Rams City Hotel Guangzhou

Arr Date Name #Nt #Rm Room Description Rate Plan Rate Resv Num
---------- ---------------- --- --- -------------------- --------- ------- --------
Total: 0

假设你的数据库文件为hotel.txt，在命令行执行下面的代码
gawk "{if($0~/*ARRIVALS:/)result=$0;if($0~/^Total:.*/)if($2!=0)print result}" hotel.txt

其中 Gawk 是个外部工具，Gawk 下载地址：

没有考虑用批处理来处理是因为文件有3万多行，太大了，用批处理来处理太慢了。

　　用纯批处理测试了一下3W多行的数据，发现速度还过得去：
@echo off :: 如果要去掉酒店编号及短横线，请把 echo !str!>>list.txt 换成 echo !str:*-!>>list.txt set bg=%time% cd.>list.txt setlocal enabledelayedexpansion for /f "tokens=1*" %%i in (test.txt) do ( if /i "%%i"=="ARRIVALS:" set str=%%j if /i "%%i"=="Total:" if %%j neq 0 echo !str!>>list.txt ) echo %bg% %time% pause
