批处理文件的文件夹检测 [英] Batch File folder detection

问题描述

是的，我知道我需要双击了一个％是一个%%在批处理文件中使用时。 ;）

Yes, I know I need to double-up the %a to be %%a when used in a batch file. ;)

这工作，但不给我我想要的结果 - 这仅仅是太多了。

This works, but does not give me the results I want - this is just too much..

FOR /f %a IN ('dir "D:\tomcat*" /ad /b ')  DO FOR /f %b IN ('dir "D:\%a\webapps" /ad /b ') DO ECHO D:\%a\webapps\%b

我真的很想做的是：

What I would really like to do is:

FOR /f %a IN ('dir "D:\tomcat*\webapps" /ad /b ')  DO ECHO %a

不过，我得到的结果错误：

But, I get the resulting error:

文件名，目录名或卷标语法不正确。

The filename, directory name, or volume label syntax is incorrect.

我想做到这一点，因为我有一个需要检测的文件夹中都有Tomcat和可以是任何如下：

I would like to do this as I have a need to detect which folders have tomcat in them and could be any of the following:

D:\tomcat
D:\tomcat1
D:\tomcat2
D:\tomcat_1
etc.

谢谢！

推荐答案

通配符（？和 * ）可用只有在使用的的最后的路径的项目，所以你必须要解决的。

Wildcards (? and *) can only be used in the last item of a path, so you will have to work around that.

至于嵌套的为的替代方法循环您正在使用，你也可以做到以下几点：

As an alternative method to the nested for loops you are using, you could also do the following:

for /F "eol=| delims=" %A in ('dir /A:D /B "D:\tomcat*"') do (> nul 2>&1 dir /A:D "%~A\webapps" && echo "%~A")

这个输出的名称中包含的tomcat 在其名称中的和所有文件夹的已经得到了一个名为的子目录的webapps 。

This outputs all folders whose names contain tomcat in their names and have got a subdirectory called webapps.

您需要提供选项字符串EOL = | delims =为 FOR / F ;这也适用于与两个嵌套为循环变体。

You need to provide the option string "eol=| delims=" for for /F; this also applies to the variant with the two nested for loops.
