OMG use Gufw

You could ask it to pause or sleep, but it would be simpler to just use GUFW.

no but if they ask for status to see if its on or not i wanted the shell to show the status, i thought the shell wouldn't close till the user either pressed ctrl-z or enter, didnt know it required something to stay open while it showed the status

With this code, it will keep going until they type "quit". If you want it to exit after any of the options, just add exit or break to said option.

#!/bin/bash

echo 'Your chance to turn your fire wall on/off or check status
================================================== ========================

Please type on/off or status'


while true; do

	read x

	case "$x" in
		on)
			sudo ufw -enable
		;;
		off)
			sudo ufw -disable	
		;;
		status)
			sudo ufw -status
		;;
		quit)
			echo "Bye!"
			exit
		;;
		*)
			echo "Invalid option"
		;;
        esac

done

I don't get how Rice's sig works.

while true; do echo -n "RiceMonster "; done

While what is true? How does the script run if there is no value that is true?

while true is true (i.e this is always going to happen) write his name to the screen, this program will continue looping until it is killed.

It's possible n pretty much every language, and it means the loop will run until either the loop is broken out of, or the program is killed. like XBehave said, true will always be true.

i did have to remove the dash's in front of enable, disable and status to get it to work in case anyone else tries that code, spot on other than that

Sorry, I'm not familiar with ufw, so I didn't know the exact syntax. My mistake.

no worries, you did do everything else for me, i don't mind have to take out a dash after that
