Need help to run a bash script

Hi Dip ??

I tried emailing you but I don’t know if you received it, I really would have liked your help customizing the function to run a bash script with parameters.

So far I have something like this (I’m not familiar with the code, please don’t laugh ?? ):

add_filter('wcra_wcra_test_callback', 'wcra_wcra_test_callback_handler');

function wcra_wcra_test_callback_handler($param)
{
	//$param = All GET/POST values will be received from endpoint
	//do your stuff here
  $param_1 = $param['P_ONE'];
  $param_2 = $param['P_TWO'];
  $param_3 = $param['P_THREE'];
  $param_4 = $param['P_FOUR'];
  echo shell_exec('/bin/bash /path/to/mybashscript.sh $param_1 $param_2 $param_3 $param_4');

}

Thank you for your help ??
