in thread How to determine the path to the Perl binary that executed your program?

Actually, it doesn't.

$ perl -le'print $^X' /usr/bin/perl $ cp /usr/bin/perl ~/tmp/ $ ./tmp/perl -le'print $^X' /home/rafl/tmp/perl

Cheers, Flo

    according to perldoc perlvar,
    Depending on the host operating system, the value of $^X may be a relative or absolute pathname of the perl program file, or may be the string used to invoke perl but not the pathname of the perl program file.
    and indeed,
    osx% perl -le'print $^X' perl

[choroba]: Why don't they use tire chains?
[perldigious]: First snow, probably not prepared right away choroba.
[stevieb]: it's Quebec... they do weird stuff there :) In the mountains, it is *mandatory* for trucks to use tire chains. Many passenger vehicles do as well (but it's not mandatory for them)
[perldigious]: That stuff can hit fast... like what we just got where I'm at. Saw a few people who had slid OUT of the roundabout I have to drive through to get to work, not used to the ice yet, take awhile to get the hang of it again and make vehicle adjustments.
[stevieb]: man, when the roads are glare ice, I don't even bother going to work or out... unless I absolutely have to, or was already out in the first place
[choroba]: Tire chains are mandatory here in mountains, and the only unprepared each year are gritters
[stevieb]: I have a 3 day winter survival kit in my vehicle in the event I get snowed in in the mountains (which has happened before due to avalanches closing the roads (and once in the summer due to a massive forest fire that trapped us
[perldigious]: a handful of people in my work area did not make it, but I live pretty close and it's flat the whole way, so I didn't have any trouble. The roundabout is the worst thing I have to negotiate.
[thezip]: G'day all!
[perldigious]: Well, that and dodging the people who forget how ice works right away. :-)
