實現(xiàn)兩個文本同行交替輸出的批處理代碼

更新時間：2010年10月11日 07:46:47 作者：

用批處理讀取兩個文本文件的內(nèi)容，并相同的行數(shù)交替輸出。

有兩個文本如下(實際中并不知道兩文本各有多少行)：

文本1.txt

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
ccccccccccccccccccccccccccccccccccccccc
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
ggggggggggggggggggggggggggggggggggggggg
wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

文本2.txt

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj

要求用批處理輸出如下(兩文本交替輸出)：

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
ccccccccccccccccccccccccccccccccccccccc
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
ggggggggggggggggggggggggggggggggggggggg

wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

復(fù)制代碼代碼如下:

 
@echo off 
setlocal enabledelayedexpansion 
for /f "delims=" %%a in ('type 11.txt') do ( 
set /a m+=1 
set "home!m!=%%a" 
) 
for /f "delims=" %%b in ('type 12.txt') do ( 
set /a n+=1 
set "bat!n!=%%b" 
) 
if %m% gtr %n% ( 
for /l %%c in (1 1 %m%) do ( 
if not "!home%%c!"=="" echo !home%%c! 
if not "!bat%%c!"=="" echo !bat%%c! 
) 
) else ( 
for /l %%d in (1 1 %n%) do ( 
if not "!home%%d!"=="" echo !home%%d! 
if not "!bat%%d!"=="" echo !bat%%d! 
) 
) 
pause
