It's a bad sign when your programming strategy shows up on The Daily WTF. But then, half of the important things I learned, I learned on TDWTF. Smilie

How about escaping things instead?
Code:
// bashescape.c
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
int safe_system(const char *strin)
{
  int m,pos=0;
  char bufout[512];

  for(m=0; (pos<511)&&(strin[m] != '\0'); m++)
  {
    char c=strin[m];
    if(!(isalnum(c) || isspace(c)))
    {
      bufout[pos++]='\\';
      if(pos >= 510) break;
    }

    bufout[pos++]=c;
  }

  fprintf(stderr,"system(\"%s\")\n",bufout);
  return(system(bufout));
}

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

Code:
# cc bashescape.c -o bashescape
# ./bashescape "echo hello ; world"
system("echo hello \; world")
hello ; world
#
