此程序用来生成<yolo v2中VOC数据生成labels所需的图片文件名文档>train.txt
linux c 读取目录及其子目录下所有.jpg文件的文件名: /xudong-bupt/p/3504442.html
我对其进行了一些小的修改，使得其可以读取目录及子目录中所有.jpg文件的纯文件名，并全部写入一个train.txt中，代码如下：
#include <stdio.h>#include <stdlib.h>#include <string.h>#include <dirent.h>#include <unistd.h>int readFileList(char *basePath,FILE* picname){DIR *dir;struct dirent *ptr;char base[1000];int namelen = 0;if ((dir=opendir(basePath)) == NULL){perror("Open dir error...");exit(1);}while ((ptr=readdir(dir)) != NULL){if(strcmp(ptr->d_name,".")==0 || strcmp(ptr->d_name,"..")==0) ///current dir OR parrent dircontinue;else if(ptr->d_type == 8){namelen = strlen(ptr->d_name);if(ptr->d_name[namelen-4] == '.' && ( ptr->d_name[namelen-3] == 'j' || ptr->d_name[namelen-3] == 'J' ) && ( ptr->d_name[namelen-2] == 'p' || ptr->d_name[namelen-2] == 'P' ) && ( ptr->d_name[namelen-1] == 'g' || ptr->d_name[namelen-1] == 'G' )) ///jpgfile{ptr->d_name[namelen-4] = '\0'; fprintf(picname,"%s\n",ptr->d_name);}}//else if(ptr->d_type == 10) ///link file//printf("d_name:%s/%s\n",basePath,ptr->d_name);else if(ptr->d_type == 4) ///dir{memset(base,'\0',sizeof(base));strcpy(base,basePath);strcat(base,"/");strcat(base,ptr->d_name);readFileList(base,picname);}}closedir(dir);return 1;}int main(){FILE* names;DIR *dir;char basePath[1000];char trainpath[1000];//pause();///get the current absoulte pathmemset(basePath,'\0',sizeof(basePath));getcwd(basePath, 999);printf("the current dir is : %s\n",basePath);strcpy(trainpath,basePath);strcat(trainpath,"/VOCdevkit/VOC/ImageSets/Main/train.txt");strcat(basePath,"/VOCdevkit/VOC/JPEGImages");printf("%s\n",basePath);///get the file list//memset(basePath,'\0',sizeof(basePath));//strncpy(basePath,"./XL",-1);names = fopen(trainpath,"a+");readFileList(basePath,names);fclose(names);return 0;}
使用方法：

creatTrainTxt.out
-VOCdevkit
-Annotations
-ImageSets
-Main
train.txt(this is what you want)
-JPEGImages
-all of pics needed
