  这应该工作（测试）

  @echo off
  set "st_line=Tue Aug 19"
  set "end_line=Clear Active on User"
  for /f "delims=:" %%i in ('findstr /inc:"%st_line%" logfile.txt') do (set st_line_ln=%%i)
  for /f "delims=:" %%j in ('findstr /inc:"%end_line%" logfile.txt') do (set end_line_ln=%%j)
  
  findstr /in /c:[a-z] /c:[0-9] /rc:"^$" logfile.txt >logfile_ln.txt
  
  set /a "st_line_ln_temp=%st_line_ln-1"
  
  for /f "skip=%st_line_ln_temp% tokens=1* delims=:" %%a in ('type logfile_ln.txt') do (
   if %%a leq %end_line_ln% (echo.%%b) 
  )
  
  del logfile_ln.txt
  

  样品输出 -

  @ECHO OFF

  我使用了一个名为 q25390541.txt 的文件，其中包含我的测试数据 . 产生 newfile.txt 和 newfile2.txt 取决于哪个是首选 .

  这是一个包含（开始和结束行显示）脚本应该完成这项工作 . 您可以修改它以排除行：

      set /a l_line=%%a
  )
   echo %l_line% -- %f_line%
  
  call :tail_head2 -file=%filename% -begin=%f_line%  -end=%l_line%

  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：

  @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
  

  如果要保留空行，则过程会慢得多 .
