[文本处理] 【已解决】BAT合并文本之间怎样就能空一行？

思想之翼

下述代码合并多个文本，中间不空行，怎样才能空一行？望指点。

@echo off
setlocal enabledelayedexpansion
for /f %%i in ('dir/b/on *.txt') do (
set/a n+=1
set m=
for /f "tokens=*" %%j in ('type "%%i"') do (
set/a m+=1
set #!n!!m!=%%j))
(for /l %%i in (1,1,%m%) do (
for /l %%j in (1,1,%n%) do (
call echo !#%%j%%i!)))>a.txt
start a.txt

set #!n!!m!=%%j 不能准确判定n和m值的吧？除非n、m值都不超过10
