将前导零添加到文件名

Question

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

3.1.19
-1
TEST
560

文件名是 v_TEST00560.TXT。如您所见，文件名中的总位数应该是 5。如果出现在第 4 行的数字是 8（见下文），那么：

3.1.19
-1
TEST
8

文件名为 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，但零的数量如果固定，并且不会根据已经存在的位数生成。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任何数字。
第二行在变量的开头填充了足够多的零。
第三行从变量中截断除了最后五个字符之外的所有字符。

Set Number=123

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