void printdir(char *dir, int depth){
DIR *dp;
struct dirent *entry;
struct stat statbuf;
if((dp = opendir(dir)) == NULL){
fprintf(stderr,"cannot open directory: %s\n",dir);
return;
}
chdir(dir);
while((entry = readdir(dp)) != NULL){
lstat(entry->d_name,&statbuf);
if(S_ISDIR(statbuf.st_mode)){
if(strcmp("..",entry->d_name) == 0||
strcmp(".",entry->d_name) == 0)
continue;
printf("%*s%s/\n",depth,"",entry->d_name);
printdir(entry->d_name,depth+4);
}
else printf("%*s%s\n",depth,"",entry->d_name);
}
chdir("..");
closedir(dp);
}
int main(){
printdir("/bin",0);
