Linux C 读取文件夹下所有文件（包括子文件夹）的文件名
#include <stdio.h>#include <stdlib.h>#include <string.h>#include <dirent.h>#include <unistd.h>int readFileList(char *basePath){DIR *dir;struct dirent *ptr;char base[1000];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) ///fileprintf("d_name:%s/%s\n",basePath,ptr->d_name);else if(ptr->d_type == 10) ///link fileprintf("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);}}closedir(dir);return 1;}int main(void){DIR *dir;char basePath[1000];///get the current absoulte pathmemset(basePath,'\0',sizeof(basePath));getcwd(basePath, 999);printf("the current dir is : %s\n",basePath);///get the file listmemset(basePath,'\0',sizeof(basePath));strcpy(basePath,"./XL");readFileList(basePath);return 0;}
个人推荐使用1的方法，因为解析的很清楚

网上看到好多这下面这段遍历文件夹下所有文件的c程序，这其实是windows下的，所以在linux下是编译不通过的，切记
#include <stdio.h>#include <io.h>int main (void){_finddata_t fileDir;long lfDir;if((lfDir = _findfirst(dir,&fileDir))==-1l)printf("No file is found\n");else{printf("file list:\n");do{printf("%s\n",fileDir.name);}while( _findnext( lfDir, &fileDir ) == 0 );}_findclose(lfDir);return 0;}
