readlink not working when parameters is surrounded with double quote

I'm trying to locate the real path of the running script , but when $0 was in some folders that contains space , readlink would fail , so i surrounded $0 with " , but readlink ceased to work this time.

  RPATH="$(readlink -f \"$0\")"
  echo $RPATH

Thanks , and if bash itself can do this , it's much more better !


Don't escape the inner quotes. As it is, they are handled to readlink as part of the filename (instead of preventing word splitting).
