处理大文件还是效率有问题

@echo off&setlocal enabledelayedexpansion
for %%i in (abc 123 456) do set _%%i=i
for /f "tokens=2 delims=:" %%i in ('findstr /n .* "1.txt"') do (
   set "str="
   for %%a in (%%i) do if defined str (set str=!str! %%a)else set str=%%a
       if defined str (
          for %%a in ("!str:~,3!") do if not defined _%%~a echo !str!&set k=
        ) else if not defined k echo;&set "k=k"
    )
pause

我上面应该是保留一行的啊

对于 忽略以abc或123或456开头的行 是直接删除呢 还是不处理连续空格但不删除呢

@echo off&setlocal enabledelayedexpansion
for %%i in (abc 123 456) do set _%%i=i
for /f "tokens=1* delims=:" %%i in ('findstr /n .* "1.txt"') do (
   set str=
   for %%a in (%%j) do if defined str (set str=!str! %%a) else set str=%%a
       if defined str (
          for %%a in ("!str:~,3!") do if not defined _%%~a (echo !str!)else echo %%j
          set "k="
        ) else if not defined k echo;&set "k=k"
    )
pause
