Question

I’ve tried this:

if (argc > 2) {
  int i;
  for(i = 0; i < argc; i++) {
    if(i != 0) {
      rename_file(argv[i]);
    }
  }
}

if I pass in two file names only the first is renamed, whats wrong with this loop?

EDIT: Heres the rename_file function (it should work I think)

void rename_file(char const *filename) {
  struct tm *clock;
  struct stat attrib;
  const char *dot = strrchr(filename, '.');
  const char *ext = NULL;
  if (dot && *dot) {
      ext = dot + 1;
  }

  stat(filename, &attrib);

  clock = gmtime(&(attrib.st_mtime));

  char newname[250];
  if (!ext) {
    printf("ERROR: No File Extenstion");
  } else {
    sprintf(newname, "%02d_%02d_%02d.%s", clock->tm_mday, clock->tm_mon, clock->tm_year + 1900, ext);
  }

  rename(filename, newname);
}

Try this:

if (argc > 2) {
  for(int i = 1; i < argc; i++) {
      rename_file(argv[i]);
  }
}
