Your apt to get more help if you try to do it on your own and post your code. I don't think you're going to find anyone to do the whole thing for you, but I'm sure plenty of people would be glad to help.

Sounds like some programming homework to me.
A

/* sample program to illustrate the opendir(), readdir() and stat()
system calls

it lists all files in the given directory, and adds an asterisk
to each one which is a subdirectory */

#include <sys/types.h>
#include <sys/stat.h>
#include <sys/dir.h>

#define MAX_CHARS 200

int CharsRead,Tmp; /* number of characters read from a directory entry */
struct direct *DirEntryPtr; /* pointer to a directory entry */
DIR *DirPtr; /* pointer to the directory */
struct stat Stat;
char Path[MAX_CHARS];

main(argc,argv)
int argc; char **argv;

{ DirPtr = opendir(argv[1]);
while (1) {
DirEntryPtr = readdir(DirPtr);
if (DirEntryPtr == 0) break; /* reached end of directory entries */
/* process file (other than . and ..) */
if (strcmp(DirEntryPtr->d_name,".") != 0 &&
strcmp(DirEntryPtr->d_name,"..") != 0) {
/* print file name */
printf("%s",DirEntryPtr->d_name);
/* build full path name of the file, for stat() */
Path[0] = 0;
strcat(Path,argv[1]);
strcat(Path,"/");
strcat(Path,DirEntryPtr->d_name);
Tmp = stat(Path,&Stat);
/* Stat now contains lots of info about the file,
e.g. its size, though we are not interested in
most of that info here */
if (S_ISDIR(Stat.st_mode)) printf("*");
printf("\n");
}
}
}

This is my trying ,,, but its so bad because there are some errors ,, If any body help me I willl thank ful for him ,,,

Here's a fixed-up version of your code:

Code:

#include <stdio.h>

#include <sys/types.h>

#include <sys/stat.h>

#include <sys/dir.h>



#define MAX_CHARS 200 // Should probably not have this and just use MAX_PATH



int CharsRead,Tmp; /* number of characters read from a directory entry */

struct direct *DirEntryPtr; /* pointer to a directory entry */

DIR *DirPtr; /* pointer to the directory */

struct stat Stat;

char Path[MAX_CHARS];

char WorkingDir[MAX_CHARS];



int main(int argc, char **argv)

{

  if(argc < 2)

    strcpy(WorkingDir, ".");

  else

    strcpy(WorkingDir, argv[1]);



  DirPtr = opendir(WorkingDir);



  while((DirEntryPtr = readdir(DirPtr)))

  {

    /* process file (other than . and ..) */

    if(strcmp(DirEntryPtr->d_name,".") && strcmp(DirEntryPtr->d_name,".."))

    {

      /* print file name */

      printf("%s", DirEntryPtr->d_name);



      /* build full path name of the file, for stat() */

      sprintf(Path, "%s/%s", WorkingDir, DirEntryPtr->d_name);



      Tmp = stat(Path, &Stat);

      /* Stat now contains lots of info about the file,

      e.g. its size, though we are not interested in

      most of that info here */

      if(S_ISDIR(Stat.st_mode))

        printf("*");

      printf("\n");

    }

  }



  return 0;

}

You had it mostly right. Only a few things.
