Question

基于此answer，我试图找到包含指定字符串的所有目录和子目录。现在我有以下代码，它显示所有目录和子目录（字符串模式未实现，这是我想要的）：

function fileNames = findAllDirectories(directory, wildcardPattern)

    import org.apache.commons.io.filefilter.*;
    import org.apache.commons.io.FileUtils;
    import java.io.File;

    files = FileUtils.listFilesAndDirs( File(directory),...
                                        NotFileFilter(TrueFileFilter.INSTANCE),...
                                        DirectoryFileFilter.DIRECTORY);

    fileNames = cellfun(@(f) char(f.getCanonicalPath()),...
                        cell(files.toArray()),...
                        'uniformOutput', false);
end

如何指定在目录/子目录名称中搜索名称模式？

例如，如果我有以下目录结构：

C:\aaa
C:\aaa\aaa
C:\aaa\bbb
C:\aaa\ccc
C:\aaa\bbb\ccc
C:\aaa\ddd
C:\aaa\ddd\bbb

我打电话给findAllDirectories('C:\aaa','ccc')，结果应为：

C:\aaa\ccc
C:\aaa\bbb\ccc

尝试使用此功能，该功能不使用任何Java库：

function dirPaths = findAllDirectories(baseDirectory, wildcardPattern)

dirPaths = recFindAllDirectories(baseDirectory);

    function matchedDirPaths = recFindAllDirectories(searchPath)
        files = dir(searchPath); % gets a struct array of the files and dirs in the dir.
        files = files(3:end); % removes '.' and '..'
        dirs = files([files.isdir]); % filters the results to directories only.
        dirNames = {dirs.name}; % takes the names of the directories
        matchedNamesIdxs = ~cellfun(@isempty, regexp(dirNames, wildcardPattern)); % applys the pattern search.
        matchedDirPaths = fullfile(searchPath, dirNames(matchedNamesIdxs)); % concats to get a full path to the matched directories.
        for i = 1:length(dirNames)
            currMatchedDirPaths = recFindAllDirectories(fullfile(searchPath, dirNames{i})); % recursively calls the function for the subdirectories.
            matchedDirPaths = [matchedDirPaths currMatchedDirPaths]; % adds the output of the recursive call to the current call's output.
        end
    end

end

使用您的目录结构，同一个调用将输出单元格数组：

＆＃39; C：\ AAA \ CCC＆＃39; ＆＃39; C：\ AAA \ BBB \ CCC＆＃39;

根据名称查找子目录和目录
