如何做循环批处理？ [英] how to do loop in Batch?

问题描述

我要创建这样的事情

dup.bat infile outfile times

例如用法是

dup.bat a.txt a5.txt 5

它会创建文件a5.txt有A.TXT重复内容的5倍

at it would create file a5.txt that has the content of a.txt repeated 5 times

但我不知道如何为循环批量做，该怎么办呢？

however I do not know how to do for loop in batch, how to do it?

推荐答案

您可以做循环是这样的：

You can do the loop like this:

SET infile=%1
SET outfile=%2
SET times=%3

FOR /L %%i IN (1,1,%times%) DO (
    REM do what you need here
    ECHO %infile%
    ECHO %outfile%
)

然后把输入文件，重复它，你可以使用更多与重定向到输入文件的内容附加到输出文件。注意这是假定这些是文本文件。

Then to take the input file and repeat it, you could use MORE with redirection to append the contents of the input file to the output file. Note this assumes these are text files.

@ECHO off
SET infile=%1
SET outfile=%2
SET times=%3

IF EXIST %outfile% DEL %outfile%
FOR /L %%i IN (1,1,%times%) DO (
    MORE %infile% >> %outfile%
)
