回复 1# 2359123467
写一个不太成熟的代码吧，凑合能使：

@echo off
set n=0
setlocal enabledelayedexpansion
(for /f "delims=" %%a in (test.txt) do (
    set /a n+=1
    if !n! leq 12 (
        set str=!str!%%a
    ) else (
        echo,!str!
        set str=%%a
        set n=1
    )
)
echo,!str!)>a.txt
pause
复制代码

下载 gawk.exe 和下面的 test.bat 脚本以及你的txt文件放在同一个目录下：

@echo off
gawk "NR%%12{printf $0;next}1" "a.txt" > "b.txt"
复制代码

双击执行 test.bat

见识了，原来set /p可以这样玩。谢谢！
应当和你的帖子http://www.bathome.net/viewthrea ... &from=favorites的用法相仿。

仔细想了想，好像觉得两者差距很大。前者给变量没有赋值（<nul），后者是将文本文件（.log）中的各行依次赋给变量。但是前者如果没有赋值，又如何实现拼接的呢？
