Getting script location, trouble with spaces

Hi,

I am writing a script and in order to run properly it needs to know
where it is located, in order to be able to find its resources. It
works fine, until the path has a space in it. I having a little
trouble resolving the issue.

#!/bin/sh

cd `dirname "$0"`
pwd
java -cp lib/myjar.jar:lib/icu4j-3_8.jar osj.main.MainClass

If at the route I have two folders:

/Applications
/Applications (Java)

and my script is in the "Applications (Java)" folder, then I always
end up in the Applications folder. At the same time if I call:

dirname "/Applications (Java)/MyApp/myapp.sh"

then this works as should.

Can anyone suggest a solution to my problem?

Andre

Never mind, solved the problem. The issue wasn't with dirname, but
with cd since I was missing some quotes:

#!/bin/sh

cd "`dirname "$0"`"
pwd
java -cp lib/myjar.jar:lib/icu4j-3_8.jar osj.main.MainClass

Beware!

#! /path/to/the/posix/sh --
or
nothing at all.

As on some systems, the POSIX sh is not in /bin and /bin/sh is
the deprecated Bourne shell.

cd -P -- "$(dirname -- "$0")"

It still won't work if the dirname of $0 ends in newline
characters because of a flaw in shells design.
