我有一个大文本文件（大约 30,000 行长），我需要从（行号 5-30）中删除一系列行，这可以使用批处理吗？
非常感谢

批处理可以做到这一点，但会有性能损失，并且有毒字符可能是一个问题 - 文件的构成可能很重要。
下载 GnuSed 并运行以下命令：
sed 5,30d "file.txt" >"file2.txt"

如果你想要一种简单的方法，你可以使用我的例程，就像编写一个命令一样简单：
Call :TEXTMAN SR RANGE_A RANGE_B "Test.txt"
PS：我为你添加了 GetRange 函数 :)
编辑：使用 300.000 行的文本文件进行测试，不到一秒钟即可获得结果。

现在它接受空行，除非 c+ c- 函数。

更新：
您只需要使用我的例程中的这部分代码：
@Echo OFF
Call :TEXTMAN 5 30 "TextFile.txt"
Pause&Exit
:TEXTMAN
(SET /A "A=0", "LINE=0", "TOTAL_LINES=0") & (CALL :%~1 %* || (ECHO Parametro incorrecto & Exit /B 1)) & (GOTO:EOF)
:GR
(For /F "tokens=1* delims=]" %%A in ('type "%~4" ^| find /n /v ""') DO (Call Set /A "LINE+=1" && (CMD /C "(IF "%%LINE%%" GEQ "%~2" IF "%%LINE%%" LEQ "%~3" (if "%%B" EQU "" (Echo+>> "%~4.NEW") ELSE ((Echo %%B)>> "%~4.NEW"))) && (IF "%%LINE%%" EQU "%~3" Exit /B 1)" || ((CALL :RENAMER "%~4") & (GOTO:EOF)))))
:RENAMER
(REN "%~1" "%~nx1.BAK") & (MOVE /Y "%~1.BAK" "%TEMP%\" >NUL) & (REN "%~1.NEW" "%~nx1") & (GOTO:EOF)
或者你可以一步一步做：
如果我们想要 X 到 Y 的范围（例如 5 到 10），那么......
1 - 将文本文件写入剪切前 5 行的 TempFile：
2 - 在 TempFile 中执行循环以开始将行写入另一个文本文件，然后在到达“Y”行时停止。
