如何通过批处理文件通配符匹配的文件循环 [英] How to loop through files matching wildcard in batch file

问题描述

我有一组基地的文件名，每个名字'F'恰好有两个文件，​​f.in'和'f.out。我想写这遍历所有文件名的批处理文件（在Windows XP），为每一个它应该：

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:

• 显示基本名称'F'


• 执行上'f.in
动作

• 执行上'f.out
其他操作

• Display the base name 'f'
• Perform an action on 'f.in'
• Perform another action on 'f.out'

我没有任何办法列出组基本的文件名，除了搜索*。在（或* .OUT）为例。

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

假设你有两个程序处理两个文件，​​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是一种替代修改，使得f只有一个文件名扩展％。

%%~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.
