How to delete content of directory using ftw

Question

We can delete non-empty directory using ftw using FTW_DEPTH. But I want to delete content of directory but not directory itself some thing similar to rm -rf dir/*.

How to achieve this using nftp/ftw ?

Answer 1

You can try this (WARNING, no confirm are required) :

#include <stdio.h>
#include <ftw.h>
#include <iostream>

using namespace std;
int list(const char *name, const struct stat *status, int type);

int main(int argc, char *argv[])
{
  ftw(argv[1], list, 1);
  return 0;
}

int list(const char *name, const struct stat *status, int type) {
  if(type != FTW_D) {
    cout << "Deleting " << name << endl;
    remove( name );
  }
return 0;
}

And call your app :

./main path_to_delete
