Top Forums Programming Trying to write a program to fill up my harddrive (Linux/C) Post 302356629 by jim mcnamara on Saturday 26th of September 2009 12:50:40 PM

Code:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
    
    char cmd2[100]={0x0};
    char cmd1[256]={0x0};
    int i=1;
    sprintf(cmd2, "df -h");

while (i<=5)
{ 
    sprintf(cmd1, "dd if=/dev/zero of=/pagefile-%i bs=1024 count=100000", i++);
    system(cmd1);
    system(cmd2);
    
  }
   return 0;
}

You do realize this is a bad idea. You may "freeze" your system
if you are doing this on the root filesystem/partition.

Other than filling a disk what are you trying to accomplish?
