Shutdown server when network inactive

I was referring script to shutdown server from local interface ubuntuforums.org/archive/index.php/t-2017336.html. This is scheduled in CRON. It will run every 20 minutes
and check for inactivity. It compares the RX and TX packets from 20 minutes ago to detect if they significantly increased. If they haven't, it will force the system to sleep.But in my case its not working properly.
I wanted to know what below expression does.
if [ $rx -le $t_rx ] || [ $tx -le $t_tx ]; then ## If network packets have not changed that much
echo "Powering off ..." >> $log

LEARN ABOUT PHP

exit

EXIT(3) 								 1								   EXIT(3)

exit - Output a message and terminate the current script

SYNOPSIS

       void exit ([string  $status])

DESCRIPTION

       void exit (int  $status)

	Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called.

       exit is a language construct and it can be called without parentheses if no $status is passed.

PARAMETERS

	      o $status
		- If $status is a string, this function prints the $status just before exiting.  If $status is an integer, that value will be used
		as the exit status and not printed. Exit statuses should be in the range 0 to 254, the exit status 255	is  reserved  by  PHP  and
		shall not be used. The status 0 is used to terminate the program successfully.

	      Note

		      PHP >= 4.2.0 does NOT print the $status if it is an integer.

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      exit example

	      <?php

	      $filename = '/path/to/data-file';
	      $file = fopen($filename, 'r')
		  or exit("unable to open file ($filename)");

	      ?>

       Example #2

	      exit status example

	      <?php

	      //exit program normally
	      exit;
	      exit();
	      exit(0);

	      //exit with an error code
	      exit(1);
	      exit(0376); //octal

	      ?>

       Example #3

	      Shutdown functions and destructors run regardless

	      <?php
	      class Foo
	      {
		  public function __destruct()
		  {
		      echo 'Destruct: ' . __METHOD__ . '()' . PHP_EOL;
		  }
	      }

	      function shutdown()
	      {
		  echo 'Shutdown: ' . __FUNCTION__ . '()' . PHP_EOL;
	      }

	      $foo = new Foo();
	      register_shutdown_function('shutdown');

	      exit();
	      echo 'This will not be output.';
	      ?>

	      The above example will output:

	      Shutdown: shutdown()
	       Destruct: Foo::__destruct()

NOTES

       Note

	      Because this is a language construct and not a function, it cannot be called using variable functions.

       Note

	       This language construct is equivalent to die(3).
