PowerShell execute command with arguments safely

In my opinion this is the best way for executing external commands from PowerShell with arguments in a safe manner - via the use of an array to hold the arguments.

Consider this one a PowerShell gem to keep in the toolbox.

Note

The example below makes use of EchoArgs.exe - a small utility that simply echoes back arguments passed to it. Utility is part of the PowerShell Community Extensions, or the exe alone can be downloaded at https://ss64.com/ps/EchoArgs.exe.

	#include <Wire.h>

	#define disk1 0x50 //Address of 24LC256 eeprom chip

	void setup(void)
	{
	Serial.begin(9600);
	Wire.begin();

	unsigned int address = 0;

	import socket

	UDP_IP = "::1" # localhost
	UDP_PORT = 5005
	MESSAGE = "Hello, World!"

	print "UDP target IP:", UDP_IP
	print "UDP target port:", UDP_PORT
	print "message:", MESSAGE
