向文件名添加前导零

Question

我正在尝试修改其他人创建的批处理文件，根据文件第 4 行中找到的数字添加前导零。实际的文件名是第 3 行中的名称和第 4 行中的数字的串联。因此，如果前几行如下所示：

3.1.19
-1
TEST
560

文件名将为 v_TEST00560.TXT。正如您所看到的，文件名中的总位数应为 5。如果第 4 行出现的数字为 8（见下文），则：

3.1.19
-1
TEST
8

文件名将为 v_TEST00008.txt。 我的文件如下：

@Echo Off 

Setlocal EnableDelayedExpansion

REM File: rename5.bat
REM The script will look for and parse one (or more) input files 
REM Input files can containrecords for one or more vessels.
REM This script assumes that each record starts with the "3.1.19" string.

如您所见，它非常复杂，我不知道如何自己进行这些更改。 BAT 运行完美，但零的数量是固定的，并且不会根据已存在的位数生成。任何帮助表示赞赏

Answer 1

我不打算阅读您的所有代码，但我用它来填充零。

第一行是您从文件中读取的数字。
第二行将足够多的零填充到变量的开头。
第三行截掉变量中除最后五个字符之外的所有字符。

Set Number=123

Set Number=00000%Number%
Set Number=%Number:~-5%
