Use a better approach than using readlink -f

It's funny that the moment I start searching for a way to get the name of the script being executed, I end up on the same source from where I learnt about readlink -f: http://tipsarea.com/2013/04/11/how-to-get-the-script-path-name-in-cshtcsh/

Hi @kaushalmodi. Maybe you are looking for this:

SCRIPTPATH=$(cd $(dirname $0); pwd -P) && cd $SCRIPTPATH

@ninrod I do use $0 and dirname but not in the same way. I need to handle the cases where the script is executed as source foo.csh vs ./foo.csh. Also, I wrap the script in a tcsh alias. I need to get the exact physical file name in that case, and that's why I need readlink.
