程序在linux上查找文件/文件夹

Question

我写了一个程序来查找linux上的文件/文件夹。

我遇到了问题，因为它只搜索主目录（用户提供的目录），并且不会进入其他文件夹并进一步开启。

如何解决这些家伙？这样它就能按预期工作。

#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <dirent.h>
#include <time.h>
#include <pwd.h>
#include <string.h>
char *kom;
void fileInfo(char *path)
{
    struct tm *time;
    struct stat bufor;
    struct passwd *p;
    struct dirent *wpis;
    stat(path,&bufor);
            time = gmtime(&bufor.st_mtime);
            p = getpwuid(bufor.st_uid);
time = gmtime(&bufor.st_mtime);
                p = getpwuid(bufor.st_uid);
                if(S_ISREG(bufor.st_mode)) printf("-");
                if(S_ISDIR(bufor.st_mode)) printf("d");
                if(S_ISLNK(bufor.st_mode)) printf("l");
                if(S_ISFIFO(bufor.st_mode))printf("p");
                if(bufor.st_mode &S_IRUSR) printf("r");
                else printf("-");

                       time->tm_mon+1,time->tm_mday,time->tm_hour,time->tm_min,
                       path);
