$dirname ??????

Hi, okay, the following command was given to me in a script, but it's not working and there's little to no help on dirname. What is wrong with the following line? I'm just trying to save the current directory to use later in subsequent scripts.
MYAPPDIR=$(dirname $(dirname $0))

$0 is the path and name of the current running script. So if you called it as /full/path/to/app it's that, and if you called it as ./app, it's only that.
Now the first (inner) dirname removes the name of the application, so it's only /full/path/to or . anymore.
With the second dirname, you're shortening it even more, becoming /full/path and . respectively.

What you probably need is a simple MYAPPDIR=$( pwd )
