How to get a pathname of executable at run-time in Common Lisp

It's NOT a load-time and compile-file-time pathname. It's equal to dirname $0 in shell scripting.

SBCL

(make-pathname :name nil :type nil
               :defaults sb-ext:*runtime-pathname*)

CCL

(truename (make-pathname :host "ccl"))

ECL

(truename (make-pathname :host "sys"))
