The value of $0 on a Linux system will be the full path to where the
script was found, so 'dirname $0' works.
However, bash runs on other OS's (Solaris for one), and Solaris does not
provide the full path in $0, you only get the name of the script.
So be careful if you're writing code that needs to be portable.
