Thank you.

The "./boo" worked. But I thought "./" was implied.

I thought by default "./boo" = "boo".

Now, I can move on to the next section. Guess I will use "./" when I am a superuser mode.

So, how do I go back to my home directory.

On the command prompt is says I am at:

root@ubuntu:/home/bun/bin

When I "ls" in that directory I see all my files and also "boo".
But when I type "boo" in the command prompt I still get:

boo: command not found

I am stuck, think I am missing something very simple.

Hi, I am new.

I have a simple question.

On Ubuntu, I made a script:

#!/bin/bash



if [ "$(id -u)" = "0" ]; then

        echo "superuser"



else 

	        echo "no"

fi

I called the file "boo".

When I run "boo" as a regular user it says "no". But when I sudo su it, it says "boo" is not a command. So, how do I make it output "superuser".

Hope this make sense.
