我想列出目录中的档案,它可以正常工作。问题是如果我在"。"我想在" ./ hello"中列出te文件。因为"。",(ls -l hello)例如。问题是,我不知道如何添加统计完整路径,任何人都可以帮助我吗?我有这段代码:
else if(strcmp(O->argv[1], "-l")==0){
if(O->argv[2]==NULL){
dir=getcwd(buffer,256);
printf("%s \n",dir);
}
else {
dir=getcwd(buffer,256);
strcat(dir,"/");
strcat(dir,O->argv[2]);
printf("%s \n",dir);
}
if ((pdirectorio=opendir(dir)) == NULL) //abrir directorio
printf("Error al abrir el directorio\n");
else {
while((directorio=readdir(pdirectorio))!= NULL){
if((stat(directorio->d_name,&info)) == -1)
printf("Fin de directorio.\n");
else {...}

只需将从readdir()获取的文件名连接到您正在遍历的目录名称即可。以下内容:
#include <stdio.h>
#include <string.h>
#include <dirent.h>
#include <sys/stat.h>
#define PATH_MAX 1024
int main(int argc, char **argv) {
DIR *d;
struct dirent *e;
char fullpath[PATH_MAX];
struct stat st;
if(argc > 1) {
if((d = opendir(argv[1])) == NULL) return 1;
} else
return 2;
while ((e = readdir(d)) != NULL) {
snprintf(fullpath, PATH_MAX, "%s/%s", argv[1], e->d_name);
if((stat(fullpath, &st)) == 0)
printf("Did stat(%s) and got block count %u.\n",
fullpath, st.st_blocks);
}
}
