Bash find where the current execution is located

Question

I have a shell program in a directory (ie dir1/dothis.sh) - works fine when I cd to that directory and ./dothis.sh

if I created a ln to that directoy with a new name - dir2 and do dir2/dothis.sh it would execute but it thinks the current execution path is the new dir where dir2 is pointing to at

in dothis.sh - how do I find where dothis.sh actually located? The problem I have is that the dir1/dothis.sh can be relocated from system to system so there is no warranty where dir1/dothis.sh can be hard code

Use the bash built-in

#!/bin/bash
echo "Current path: $PWD"

echo $a
b=$a"/"$0
echo `dirname $b`

How about

dirname $(readlink -f $0)

It will also resolve symbolic link if any...
