批处理脚本循环 [英] Batch script loop

问题描述

我要执行命令100-200倍，到目前为止，我的研究表明，我要么必须复制/粘贴此命令的100个拷贝，或使用为循环，但 环路期望的项目清单，因此我需要200个文件进行操作，或200项列表，从而击败了点。

I need to execute a command 100-200 times, and so far my research indicates that I would either have to copy/paste 100 copies of this command, OR use a for loop, but the for loop expects a list of items, hence I would need 200 files to operate on, or a list of 200 items, hence defeating the point.

我宁可不要写一个C程序，并通过记录的长度，为什么我不得不写另一个程序来执行用于测试目的，我的计划。我的程序本身的修改也是不是一个选项。

I would rather not have to write a C program and go through the length of documenting why I had to write another program to execute my program for test purposes. Modification of my program itself is also not an option.

所以，对于一个命令，＆LT;一>，我将如何通过批处理脚本执行了N次

So, given a command, <a>, how would I execute it N times via a batch script?

推荐答案

为/ L 是您的朋友：

for /l %x in (1, 1, 100) do echo %x

由一个从1开始，步骤，并在100结束。

Starts at 1, steps by one, and finishes at 100.

使用两个％■如果它在一个批处理文件

Use two %s if it's in a batch file

for /l %%x in (1, 1, 100) do echo %%x

（这是我真的真的很讨厌有关Windows脚本的事情之一）

(which is one of the things I really really hate about windows scripting)

如果您有循环的每个迭代多个命令，这样做：

If you have multiple commands for each iteration of the loop, do this:

for /l %x in (1, 1, 100) do (
   echo %x
   copy %x.txt z:\whatever\etc
)

或批处理文件中的

or in a batch file

for /l %%x in (1, 1, 100) do (
   echo %%x
   copy %%x.txt z:\whatever\etc
)
