我有一系列日志文件。
我用findstr解析这些日志文件以确定文本字符串的第一个实例，然后返回文件名和找到匹配的行木材作为变量。
然后我使用findstr来解析找到匹配的文件以获取另一个文本字符串。我将匹配的行号作为变量返回。
我现在有了文件，起始和结束行号。
我需要在行号之间返回文本块。
所有输出都被重定向到由变量casenotes
表示的文本文件这是我的代码：
:test
echo: >> %casenotes%
echo: test >> %casenotes%
for /f "tokens=1,2* delims=:" %%a in ('findstr /N /C:"Optimize ThreadPools" *_MAGT_*.txt') do set startline=%%b & set filefoundin=%%a & goto part2
:part2
for /f "tokens=1,2* delims=:" %%a in ('findstr /N /C:"After optimization" %filefoundin%') do set endline=%%a & goto part3
:part3
echo: >> %casenotes%
echo: filefound in: %filefoundin% >> %casenotes%
echo: startline is: %startline% >> %casenotes%
echo: endline is: %endline% >> %casenotes%
echo: >> %casenotes%
echo: now do something magic to read everything between lines %startline% and %endline% from %filefoundin% and redirect that output to %casenotes%

试试这个： @echo off
set file_to_read=read.txt
set /a start_line=1
set /a end_line=6
set outfile=outfile
set counter=1
break > %outfile%
setlocal ENABLEDELAYEDEXPANSION
for /f "delims=*" %%A in (%file_to_read%) do (
if !counter! GEQ !start_line! (
echo %%A
echo %%A >> !outfile!
)
set /A counter=!counter!+1
if !counter! GEQ !end_line! (
goto :endLoop
)
)
:endLoop
这不会计算空行。

@Echo OFF
Set "File=Test.txt"
Set /A "Start_Line=3"
Set /A "End_Line=6"
For /F "Tokens=*" %%# In ('Type "%FILE%"') DO (
Call Set /A "Line+=1"
CMD /C "IF %%LINE%% GEQ %Start_Line% IF %%LINE%% LEQ %END_Line% (Echo %%#>>"Output.txt")"
)

具有相同准确度的另一种方式
@Echo OFF
Set "File=Test.txt"
Set /A "Start_Line=3"
Set /A "End_Line=6"
For /F "Tokens=* delims=" %%# In ('Type "%FILE%"') DO (
Set /A "Line+=1"
CALL :READ_LINES "%%#"
)
:READ_LINES
(IF %LINE% GEQ %Start_Line% IF %LINE% LEQ %END_Line% (Echo %*>>"Output.txt") ELSE (GOTO:END)) & GOTO:EOF
:END
Pause&Exit
对于任何其他类型的文本操作，您可以在下次使用我的TEXTMAN子例程（西班牙语中的注释行，抱歉）：

下面的批处理文件是最快的方法，特别是如果文件很大。
echo: read everything between lines %startline% and %endline% from %filefoundin% and redirect that output to %casenotes%
setlocal EnableDelayedExpansion
set skip=
set /A skiplines=startline-1, numlines=endline-startline+1
if %skiplines% gtr 0 set skip=skip=%skiplines%
(for /F "%skip% delims=" %%a in (%filefoundin%) do (
echo %%a
set /A numlines-=1
if !numlines! equ 0 goto part4
)) > %casenotes%
:part4
如果文件包含感叹号，则需要进行少量修改以避免延迟扩展。如果您需要，请提出要求。
请注意，此解决方案会忽略文件中的空行。如果需要，也可以解决这个细节。
