in reply to Pipe Question

On my Unix system, scripts are not executable from the current directory without preappending "./" to the filename.

Your scripts works fine when I replace your open statement with:

open (P, "| ./from.pl");

    It shouldn't, unless you're writing to P. See my response below.

    What you're probably seeing is from.pl writing to stdout, and you're not getting a count of 4 underneath the words.
      You're correct about the placement of the pipe (and not getting a count without its correct placement).

      But on my system this works:

      open (P, "./from.pl |");

      and this does not work:

      open (P, "from.pl |");

      From the shell I must always specify a script's path, unless the path is defined in PATH.

[Corion]: Meh. I need to find myself a better "programming" feed than r/programming (which is just HackerNews reposts and advertisements, very little code). Maybe I should select a list of links that I liked on r/programming and then google for ...
[Corion]: ... an aggregator site that also listed (ideally) all of these links once. And maybe also have an exclude list to blacklist some of the most spammy links that the site may have never mentioned at all
[marto]: I gave up reading HN at all, and feel much better for it :P
[Corion]: Now, how to best automate that Google search ... :-)
[Corion]: marto: Yeah, I'm also short of not reading it at all. I already stopped reading it in the morning because it gave me a foul mood.
[Corion]: The good posts on HN are the non-computing posts. Most of the other stuff is maybe relevant to you if you are 20 and live in Silicon Valley...
[Corion]: Two attributes that don't describe me.
[Corion]: Maybe I should also write a curator for HN or simply not read it anymore, like you do.
