.BAT文件循环编号 - 需要添加0到小于10的数字 [英] .BAT file to loop through numbers - Need to add 0 to numbers less than 10

问题描述

我有一些.bat文件正在打开一个程序，并找到一个每天运行的特定实例。这个实例有时间戳，每天都会改变。所以我有.bat文件运行通过everynumber查找该实例。格式是YYYYMMDDHHMMSS。

从这个网站我已经有一个.bat文件，发现前一个工作日。我甚至有循环的数字

问题是如果数字小于10，它需要在它前面有一个0：
01 ，02,03,04 etc ...
.bat文件吐出来的方式是1,2,3等...

这里是我已经到目前为止的代码：

 对于/ L %% G IN（3,1,9）DO （
 For / L %% H IN（0,1,59）DO（
如果%% H LSS 10 SET %% H = 0 %% H 
 ECHO％prevbusday％0％ ％G %% H 
）
）
超时/ t 60 
  

第一行循环遍历小时（3至9）

嵌套公式循环遍历分钟（0至59）

解决方案

你不能直接修改 %% H 。您必须设置variable = %% H，并使用延迟扩展来检索！variable！。只要你设置另一个变量，只要使用可变的子字符串。预先设置为零，然后使用最右边的两位数字。

$ b

setlocal enabledelayedexpansion

对于/ L %% G IN（3,1,9）DO（
For / L %% H IN（0,1,59）DO（
seth = 0 %% H
ECHO％prevbusday％0 %% G！h：〜-2！
）
）
timeout / t 60


I have a number of .bat files that are opening a program and finding a specific instance that is ran everyday. This instance is timestamped and changes everyday. So I am having the .bat file run through everynumber looking for that instance. The format is YYYYMMDDHHMMSS.

From this site I already have a .bat file that finds the previous business day. I even have it looping through the numbers

The problem is if the number is less than 10, it needs to have a 0 in front of it: 01,02,03,04 etc... The way the .bat file spits it out, though, is 1,2,3 etc...

Here is the code I have so far:

For /L %%G IN (3,1,9) DO (
    For /L %%H IN (0,1,59) DO (
        If %%H LSS 10 SET %%H=0%%H
            ECHO %prevbusday%0%%G%%H
    )
)
timeout /t 60

The first line loops through the hours (3 to 9)
The nested formula then loops through the minutes (0 to 59)

解决方案

You can't modify %%H directly. You have to set "variable=%%H" and use delayed expansion to retrieve !variable!. As long as you're setting another variable anyway, just use variable substrings. Prepend a zero to everything, then use the rightmost two digits.

setlocal enabledelayedexpansion

For /L %%G IN (3,1,9) DO (
    For /L %%H IN (0,1,59) DO (
        set "h=0%%H"
        ECHO %prevbusday%0%%G!h:~-2!
    )
)
timeout /t 60
