    	int n, i;
    	char pathname[100];
    	getcwd(pathname);
    	n = scandir(pathname, &namelist, 0, alphasort);
    	if (n < 0) {
    		perror("scandir");
    	}
    	else {
    		for (i = 0; i < n; i++) {
    			if (namelist[i]->d_name[0] != '.') {
    				printf("%s \n", namelist[i]->d_name);
    			}
