@EliahKagan I read a very good answer from you but reading it i couldn't help myself but laugh a lot. This one. Why i had to laugh a lot you might ask. Well the word penner has in german the meaning bum.

haha :)

I do sometimes try to inject some levity into my answers, but I assure you it was unintentional here. In the case of that answer, it's the OP's username (as well, it seems, as his surname), why I used it.

I know hehehe

but that works both ways tbh, the german word dick is such an example which has a different meaning in english, but would be translated from german to enlish as fat,thick, bulky, corpulent

the risks of multiligual environments :) I remember I apparently managed to say something terrible in a language I don't know at all by trying to write a dialect poem from my region phonetically

yes :)

I'm distracted by an even weirder problem.

Which as far as I know has nothing to do with Ubuntu.

But this is the Island so what the heck.

whats the problem?

That answer reports that a "relatively recent version of Perl" is needed to run this script. The script doesn't show any sign of relying on new features, and on Ubuntu 16.04 LTS it does work with old versions of perl such as 5.6.2 and perl 5.8.9 (installed through perlbrew).

But it does not work on Mac OS X 10.4.11 Tiger, which has perl 5.8.6, and the reason is that perl on that system thinks m is not in the character class [@-~]. Locale doesn't seem to affect this; I am testing mainly with the "C" locale. However, grep on that system does know m is in [@-~]!

I don't know if this is the same reason the OP had to install a new version of perl on their much more recent macOS system, nor am I sure they did actually have to do that, but this is an moderately interesting and extremely vexing problem of its own that is getting in the way of me posting what I had thought was my almost finished answer to their question.

no clue here sorry

The next step would normally be for me to install a newer version of perl on that system and see if the problem goes away. But the system is so old. Also it is not connected to the Internet. Also it hasn't received security updates for more than seven years.

@EliahKagan that seems very odd

I don't even know how one is supposed to install software on MacOS

Maybe perlbrew.pl will work that far back. But I would still need to connect the machine to the Internet.

:S

Well I have an idea. Maybe.

anyone any ideas here [askubuntu.com/questions/973448/…) im out of my wits

utterly irrelevantly... I got a tax refund \o/
