我想要在蓝色字体的2行冒号以后的数字不显示，其他所有的输出到comparelog中去，写了如下命令：
for /f "delims=: tokens=17" %%i in (log.txt) do echo %%i > comparelog.txt
但是没有comparelog文件生成，是我命令用法不对吗？谢谢！
我倒是有另一种办法能达到同样目的
setlocal ENABLEDELAYEDEXPANSION
set STR1=Rows transferred: 41
SET STR2=Rows transferred:
for /f "tokens=* delims=" %%a in (log.txt) do (
set n=%%a
set n=!n:%STR1%=%STR2%!
echo !n!>>comparelog

谢谢！学习下！作者: Lumiere 时间: 2009-4-2 11:21
鉴于文本中有数字41的的行就是蓝色字体部分的两行，所以用字符串替换就可以。
setlocal enabledelayedexpansion
for /f "delims=" %%a in (log.txt) do set var=%%a&echo !var:41=!>>logcompare.txt
pause
