This isn't necessarily a Mac-specific question, but I've gotten rusty
and I'm having a brain fart here.
How can a Perl script reliably, portably resolve the path inside which
it is running? Not the PWD of the caller, mind you, but the actual
current full path of the script itself?
$0 That's a zero. Has always worked for me to produce a full path
to a running perl script.
$ENV{PWD} is, as you say the working directory when perl, or the
script as an executable with a shebang line
There is a module "cwd" I think which will keep $ENV{PWD} correct as
you change directories around within a script..
As for portability to other than *NIX, I donno.
