如何遍历批处理文件中匹配通配符的文件 [英] How to loop through files matching wildcard in batch file

问题描述

我有一组基本文件名，对于每个名称f"，恰好有两个文件，f.in"和f.out".我想编写一个批处理文件(在 Windows XP 中)，它遍历所有文件名，对于每个文件名:

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'
• 对f.in"执行操作
• 对f.out"执行另一个操作

我没有任何方法可以列出一组基本文件名，只能搜索 *.in(或 *.out).

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，它仅将 %f 扩展为文件名.请参阅 https://technet.microsoft.com/en-us/library 中的其他修饰符/bb490909.aspx(页面中间)或就在下一个答案中.

%%~nf is a substitution modifier, that expands %f to a file name only. See other modifiers in https://technet.microsoft.com/en-us/library/bb490909.aspx (midway down the page) or just in the next answer.
