I guess one might ask why you're throwing away all of the debugging data you have collected whenever your script is invoked with the first operand set to pre?

I guess one might ask why you don't include any timestamps in your debugging output?

I guess one might ask why you don't include a set -vx command at the start of your script and save the diagnostic information that would produce in a log file?
Nothing appears in ]/tmp/systemd_suspend_test.txt. Because if it did, the script would be working. :-)

As to your 1st guess, I have no idea how to implement what you are asking. i.e. The reason for my post.

Same with your 2nd and 3rd guesses.

The script use two parameters:

Nothing new happened.

My code is a modification of what is here.

AIRPORT2-PORTINSPECTOR(1)				      General Commands Manual					 AIRPORT2-PORTINSPECTOR(1)

NAME

       airport2-portinspector - Port maps inspector for the Apple AirPort Extreme Base Station ("Snow")

SYNOPSIS

       airport2-portinspector

DESCRIPTION

       airport2-portinspector allows you to inspect the port maps used by the hosts associated with your base station.

OPTIONS

       airport2-portinspector  accepts	no  command-line options. airport2-portinspector is a wrapper script around the PortInspector.jar jar file
       located in /usr/share/java/airport-utils.

       You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG  environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The  full  path  to  the	Java  Virtual  Machine	to  use.  By  default,	the  wrapper  uses JAVACMD; if it is not set, it looks for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
