If you're wanting to run a command and have the output go directly to a file you might want to look at shell?
https://docs.perl6.org/routine/shell You can still get back a Proc object and specify if you want access to the input, output of error handles. So if you wanted to call an external command, pass it some data but have it write out to a file you can do something like this: perl6 -e 'my $p = shell "cat > foo.txt", :in;$p.in.say("test");$p.in.close()' The :in adverb says I want the in handle opened which I then write to and close :) Hope that helps.
