OK, That worked. Your comment, "It sets the special variable to undef", is not yet clear to me. I will have to research this. I greatly appreciate you help. I understand the concept of $_, just not how local $/ modifies it.

    It doesn't modify the behavior of $_, but of <INFILE> (for any handle).

    Perl has a bunch of special variables that change the behavior of perl. $/ Is one of them, it changes what string readline, and thus <INFILE>, searches for as a line terminator, to read a whole line at once. When undef, it'll just make it slurp in the rest of the file.

    OK, that makes sense now. Thanks again.

[marto]: Eily you can't remote connect the physical device via USB ;)
[Corion]: Eily: Sure, that's what I do, but some things you need to do on the Android device directly, like when navigating the bootloader :-)
[Eily]: marto you just need a longer cable :P
[Corion]: marto: Yeah, but I'm somewhat wary of installing random USB drivers downloaded from , Google Drive or whatever, so Linux wins there due to there being no conflicts and me just having to edit one text file in the worst case, to add the USB vendor
[hippo]: Long USB cable FTW.
[Corion]: Eily: I've thought of that, but I don't like running long cables through the appartment because sooner or later I'll trip over it, pulling at least one device off its stand :)
[marto]: hmm, may have to patch CPAN::Meta to move from search.cpan to metacpan in the META.json/yml files
[Corion]: marto: Heh - it seems that they plan to keep the links alive for a long time. But still, I plan on moving PM to use/generate the new links
[Corion]: And I think it's better to generate links to the new world instead of keeping the older links alive by generating new versions of them ;)
[marto]: yeah, I guess it's supposed to be a permanent redirect, but better to make the move where possible
