Re: Re: Find the full path of the script at run time

Thanks. I think this is what I will be going for.

I also found This thread, and was considering FindBin, but apparently FindBin is broken.

I'd still be interested in other options. If my script is invoked as ..\..\script.pl, won't that set $0 to ..\..\script.pl ?

Cheers,
ibanix

$ echo '$0 & $0 &' > foo; chmod a+x foo; foo;

FindBin

Anyway, to answer your question: yes, $0 would be set to ..\..\script.pl. That's where tye's solution, rel2abs, would again come to the rescue. A demo of a full solution, as tye merely mentioned the function name:

use File::Spec::Functions 'rel2abs';
print rel2abs($0);

update: Oh dear, it doesn't. The double dots are still in the created path. For Unix, that is the safest, as you never know which "directory" is actually just a link to another directory, so by following "foo/.." you could end up in an entirely different directory from where you started from.

It doesn't look as neat, but it works just as well.
