A.txt内容如下：
a A aa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 b B bb 1 2 c C cc 1 d D dd 1 2 3 4 5
期望输出结果到B.txt如下：
a A aa 1 a A aa 2 a A aa 3 a A aa 4 a A aa 5 a A aa 6 a A aa 7 a A aa 8 a A aa 9 a A aa 10 a A aa 11 a A aa 12 a A aa 13 a A aa 14 a A aa 15 a A aa 16 b B bb 1 b B bb 2 c C cc 1 d D dd 1 d D dd 2 d D dd 3 d D dd 4 d D dd 5

自己写了个笨代码，觉得十分丑陋。。。望达人指点
@echo off&&setlocal enabledelayedexpansion for /f "tokens=1-20 delims= " %%a in (A.txt) do ( >>A_1.txt echo %%a %%b %%c %%d >>A_1.txt echo %%a %%b %%c %%e >>A_1.txt echo %%a %%b %%c %%f >>A_1.txt echo %%a %%b %%c %%g >>A_1.txt echo %%a %%b %%c %%h >>A_1.txt echo %%a %%b %%c %%i >>A_1.txt echo %%a %%b %%c %%j >>A_1.txt echo %%a %%b %%c %%k >>A_1.txt echo %%a %%b %%c %%l >>A_1.txt echo %%a %%b %%c %%m >>A_1.txt echo %%a %%b %%c %%n >>A_1.txt echo %%a %%b %%c %%o >>A_1.txt echo %%a %%b %%c %%p >>A_1.txt echo %%a %%b %%c %%q >>A_1.txt echo %%a %%b %%c %%r >>A_1.txt echo %%a %%b %%c %%s >>A_1.txt echo %%a %%b %%c %%t ) for /f "tokens=1-20 delims= " %%a in (A_1.txt) do ( if "%%d" neq "" >>B.txt echo %%a %%b %%c %%d)

如果每列的字符不含空格：
@echo off (for /f "tokens=1-3,*" %%1 in (a.txt) do ( for %%a in (%%4) do echo %%1 %%2 %%3 %%a ))>b.txt

惭愧，FOR的用法我还是知道的太少了
完美的代码
