Determine FULL name of current script

Hi everyone,

Is there a slick way to determine the FULL name of a script that is running?

The variable

${0}

just gives the relative path name.

I guess I could just do the following:

FULL_SCRIPT_NAME=${PWD}${0}

Although that's pretty simple is there another way that I am missing?

Thanks a lot.

Mike

Hi vgersh99,

I meant to specify that I am using the bash shell. A quick web search seems to indicate that whence is a ksh function, and whence ls does not work on my system. Am I correct about that? Any other suggestions?

If you're running bash, you may be on linux, and may thus have the general purpose command 'realpath'.

#!/bin/bash
#set -x

progpath=$(
  progpath=$0
  case $0 in
    (*/*) ;; (*)
      [ -e "$progpath" ] || progpath=$(command -v -- "$progpath") || exit
  esac
  cd -P -- "$(dirname -- "$progpath")" && pwd -P || exit
) || exit
progpath=$progpath/$(basename "$0")
echo "${progpath}"
