问题描述

我有一个如下所示的日志文件.

I have a log file like below.

我想提取以"[[Tue Aug 19 10:]"开头的行，直到以"Clear Active on User"开头的行，并使用Windows批处理脚本输出到文件.我尝试了下面的代码.它仅输出最后一行.

I want to extract the line starting with "[Tue Aug 19 10:" until the line that starts with "Clear Active on User" and output to a file using windows batch script. I tried the below code. It only outputs the last line.

@echo off& setlocal enabledelayedexpansion

@echo off & setlocal enabledelayedexpansion

设置Month_Num =％date:〜4,2％

set Month_Num=%date:~4,2%

如果％Month_Num％== 08设置为Month_Name = Aug

if %Month_Num%==08 set Month_Name=Aug

设置日期=％日期:〜0.3％

set Day=%date:~0,3%

设置Today_Date =％date:〜7.2％

set Today_Date=%date:~7,2%

set Search_String = [％Day％％Month_Name％％Today_Date％10:

set Search_String=[%Day% %Month_Name% %Today_Date% 10:

对于/f"tokens = 1 delims = []" %% a in('find/n％Search_String％" ^

for /f "tokens=1 delims=[]" %%a in ('find /n "%Search_String%"^

推荐答案

下面的批处理文件旨在尽可能快地处理大文件.但是，它会从结果中删除空行:

The Batch file below was designed to process as fast as possible a big file; however, it deletes empty lines from result:

@echo off
setlocal EnableDelayedExpansion

set "start=[Tue Aug 19 10:"
set "end=Clear Active on User"

for /F %%a in ("%start%") do set startWord=%%a
for /F %%a in ("%end%") do set endWord=%%a

set "startLine="
set "endLine="
for /F "tokens=1,2 delims=: " %%a in ('findstr /I /N /B /C:"%start%" /C:"%end%" logFile.txt') do (
   if not defined startLine if "%%b" equ "%startWord%" set startLine=%%a
   if not defined endLine if "%%b" equ "%endWord%" set "endLine=%%a" & goto continue0
)
:continue0
set /A skipLines=startLine-1, numLines=endLine-startLine+1
set "skip="
if %skipLines% gtr 0 set skip=skip=%skipLines%

(for /F "%skip% delims=" %%a in (logFile.txt) do (
   echo %%a
   set /A numLines-=1
   if !numLines! equ 0 goto continue1
)) > outFile1.txt
:continue1

rem Previous outFile1.txt contain as many extra lines as empty lines removed, so we need to eliminate they

for /F "delims=:" %%a in ('findstr /I /N /B /C:"%end%" outFile1.txt') do set numLines=%%a
(for /F "delims=" %%a in (outFile1.txt) do (
   echo %%a
   set /A numLines-=1
   if !numLines! equ 0 goto continue2
)) > outFile2.txt
:continue2

del outFile1.txt
TYPE outFile2.txt

如果您要保留空行，则过程会慢很多[em] .

If you want to preserve empty lines, the process would be much slower.
