魂影影子

bat批处理提取多个文本文件的第三行并输出保存到ok.txt

什么写

魂影影子

@echo off
setlocal enabledelayedexpansion
(for %%i in (*.txt) do (
    set "var="
    (for /l %%j in (1 1 3) do set /p var=)<"%%i"
    echo;!var!
))>ok.txt


老大说的对，多使用论坛搜索，已解决，谢谢各位

tl的用法，
提取文本文件filename的第n行到第m行

tl [filename] [n] [m]
复制代码

只提取第n行

tl [filename] [n] 
复制代码

提取倒数第3行

tl [filename] -3 
复制代码

提取第5行到文件结束

tl [filename] 5 -1 
复制代码

基础版tl只支持utf8和ansi编码，我还是不会判断无bom的utf8，显示utf8不会乱码，且几十兆上百兆的txt也轻松在一两秒内解决掉。是more和type的替代品。速度快，体积只有3K。用base64加权压缩了。
