如何在批处理文件中循环匹配通配符的文件 [英] How to loop through files matching wildcard in batch file

问题描述

我有一组基本文件名，对于每个名字'f'有正好两个文件'f.in'和'f.out'。我想写一个批处理文件（在Windows XP中），它遍历所有文件名，每个文件名应该：

I have a set of base filenames, for each name 'f' there are exactly two files, 'f.in' and 'f.out'. I want to write a batch file (in Windows XP) which goes through all the filenames, for each one it should:

• 显示基础name'f'


• 对'f.in'执行操作


• 对'f.out'执行另一个操作

我没有办法列出基本文件名的集合，除了搜索* .in（或* .out）例如。 / p>

I don't have any way to list the set of base filenames, other than to search for *.in (or *.out) for example.

推荐答案

假设您有两个程序来处理这两个文件：process_in.exe和process_out.exe：

Assuming you have two programs that process the two files, process_in.exe and process_out.exe:

    for %%f in (*.in) do (

            echo %%~nf
            process_in "%%~nf.in"
            process_out "%%~nf.out"
    )

%%〜nf是一个替换修饰符，它将％f扩展为文件名。
请参阅 https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/batch.mspx?mfr=true （页面中间）或刚才下一个答案。

%%~nf is a substitution modifier, that expands %f to a file name only. See other modifiers in https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/batch.mspx?mfr=true (midway down the page) or just in the next answer.
