Todd, I see that you’re frequently running commands in your code like me. I was looking for a reliable reusable approach for commands for a long time. I’m still learning & not quite ready to step up to contribute to the ecosystem yet (https://docs.perl6.org/language/modules.html). After reading Perl 6 Fundamentals (Moritz Lenz), I cobbled together a reusable Command.pm6 for myself based on his examples. Method ‘run’ for a single async command, or methods ‘sow’+‘reap’ for multiple async (possibly all different) commands, with all returns collected in Command::Result objects.
https://github.com/markldevine/perl6-Command Now whenever I need any general-purpose external command, I ‘use Command;’ and it has never failed me (I.e. curl, , ssh, etc.). Because it’s not in the ecosystem, git clone it into a directory and set PERL6LIB=<dir > or ‘use lib <dir>’ internally. Docs are internal POD. If any of the Perl 6 big brains are reading this and would provide some welcome criticism resulting in something that should be published, I would upload as per the instructions it or hand it off to someone more capable of maintaining it. If you give it a try, I think that you might find it helpful.

Yes, that's what I was addressing: you can tell run() to do that, keeping stderr separate with :err(). qxx does that internally.

Hi Brandon, I adore the run command. In this particular instance (curl's progress meter, which is written to STDERR), I want STDERR to write to the shell, but want to collect STDIN and the return code. curl xxxx; echo $? will send both to STDIN, which I can easily deal with. -T -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com<mailto:allber...@gmail.com> ballb...@sinenomine.net<mailto:ballb...@sinenomine.net> unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
