Re: How to take down a system to the point of requiring a newfs with one line of C (userland)

Purely in the interest of showing off, here is my version. It is 81
bytes shorter than yours, it is valid C99 with POSIX extensions (yours
is not), and it produces 11,450 files in about 0.2% of the time yours
takes to produce 10,000.

#include <unistd.h>
#define b(i,v) for(int v=48;v<127;++v){f[i]=v;
#define a(i) b(i,v##i)
int main(void){char f[5]={'/'};a(1)a(2)a(3)truncate(f,0);}}}}

Two bugs:

1) I forgot to include the correct version of the code

2) the version I had created a few files with '/' in their names; this
slightly nastier creates 10,648 files with only letters.

#include <unistd.h>
#define b(i,v)for(int v=65;v<87;){i[f]=v++;
#define a(i)b(i,v##i)
int main(void){char f[4]={47};a(1)a(2)a(3)truncate(f,0);}}}}
