Harry,
How do you know when to crtl-c the shell script?
And can you change the shell script to finish gracefully instead?
I don't think fork or system will help as they don't give you the PID of the called script, Fork gives you the PID of the child.
You might try something like this; 
my $rc = fork;
if($rc == 0){
  #child
  system("run_shell_script");
}else{
  #parent
  #decide when to kill shell script by killing child
  #not sure if this won't create a zombie shell script 
  #and system dosen't return a PID
  kill 9, $rc;
}
