codeigniter .cgi files

I want to utilize a .cgi file in a function call within my model:

function execute_shell_command($userID,$clientname){

  $shell_script_to_execute="jobscript.cgi";
  $jobtype="clientjob";

  echo shell_exec("bash '".$shell_script_to_execute."' '".$jobtype."' '".$userID."' '".$clientname."' '".$this->job_command."' '".$this->job_id."' '".$this->servername."开发者_StackOverflow社区'  '".$this->rootaccess."'  ");

}

How do I load this cgi file, right now I don't know where to put it. In my assets folder? Just looking for a good way to do it in codeigniter

File paths in codeigniter are always relative to index.php so if your cgi-bin directory is sitting at the same level as your index.php

$shell_script_to_execute = "./cgi-bin/jobscript.cgi";

should work...
