's' case with getopt dosent print out the active files - c

Question

This certain getopt case is supposed to be used as an ls (the unix/linux command) alternative that returns the active files but once compiled and ran nothing is returned in the terminal.
Here is the full code:
#include <errno.h>
#include <getopt.h>
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <dirent.h>
#define DATA_SIZE 1000
void print_help(void)
{
printf("Help\n");
printf("> cast -d (deletes file)\n");
printf("> cast -r (renames file)\n");
printf("> cast -c (create new file)\n");
printf("> cast -s (searches contents of file)\n");
printf("________________________________________\n");
printf("Find an error or a bug? please submit it in the issues section on github\n");
}
case 's': {
int main(void)
{
DIR *directory;
struct dirent *entry;
directory = opendir(".");
if (directory == NULL)
{
printf("Error reading directory\n");
return 1;
}
while ((entry = readdir(directory)) != NULL)
if (entry->d_type == DT_REG)
{
printf("file: %s\n", entry->d_name);
}
}
if (closedir(directory) == -1)
{
printf("Error closing directory\n");
return 1;
}
return 0;
}
}
int main(int argc, char **argv)
{
int option_val = 0;
int opt_delete = 0;
int opt_help = 0;
int opt_rename = 0;
int opt_create = 0;
int opt_search = 0;
while ((option_val = getopt(argc, argv, "dhrcs")) != -1) {
switch (option_val) {
case 'd': {
char filename[65]; //Hope your filename isnt bigger than this
printf("Filename or path to file: ");
scanf("%s", filename); // checks to see if your filename isnt bigger than specified
if (remove(filename) != 0)
{
fprintf(stderr, "Errno: %d\n", errno);
perror("Error msg");
} else printf("%s, deleted.\n", filename);
opt_delete = 1;
break;
case 'r': {
char file[65], new[65];
printf("File: ");
scanf("%s", file);
printf("New name: ");
scanf("%s", new);
if (rename(file, new) != 0)
{
fprintf(stderr, "Errno: %d\n", errno);
perror("Error msg");
} else printf("%s --> %s", file, new);
opt_rename = 1;
break;
case 'c': {
FILE *f = fopen("Castdocument.txt", "w+");
fprintf(f, "Finished with maybe no errors? Rename this file to whatever you would like and change the filename extension with ""cast -r""");
printf("File created! (Check your home directory for ""Castdocument.txt"" file and modify that to fit your needs)");
fclose(f);
opt_create = 1;
case 'h': {
print_help();
opt_help = 1;
break;
default:; /* '?' */
//print_help();
}
if (opt_delete) {
printf("\n");
} if (opt_rename) {
printf("\n");
} if (opt_help) {
print_help();
} if (opt_search) {
printf("\n");
} if (opt_create) {
printf("\n");
}
}
}
}
}
}
}
and here is the 's' case:
case 's': {
int main(void)
{
DIR *directory;
struct dirent *entry;
directory = opendir(".");
if (directory == NULL)
{
printf("Error reading directory\n");
return 1;
}
while ((entry = readdir(directory)) != NULL)
if (entry->d_type == DT_REG)
{
printf("file: %s\n", entry->d_name);
}
}
if (closedir(directory) == -1)
{
printf("Error closing directory\n");
return 1;
}
return 0;
}
}
I attempted to move the case out of the switch statement but to no avail.
