The documentation has a nice example showing how to run an external program and how to get its output or even its standard error. https://docs.perl6.org/type/Proc
However it looks a lot more complex than the plain backtick Perl 5 has and more complex than the capture function of Capture::Tiny. IMHO it is way too much code. I wrote a simple function wrapping it: sub capture(*@args) { my $p = run @args, :out, :err; my $output = $p.out.slurp: :close; my $error = $p.err.slurp: :close; my $exit = $p.exitcode; return { out => $output, err => $error, exit => $exit; }; } It can be used as: my $res = capture($*EXECUTABLE, 'bin/create_db.pl6'); say $res<out>; or even say capture($*EXECUTABLE, 'bin/create_db.pl6')<out>; I wonder if I have just invented something that already exist in Rakudo or if it is not there, then wouldn't it be a good idea to add such a simple way to run external commands? regards Gabor ps. Backtick actually expected a single string and not a list of parameters and supporting that mode, even if it is less secure, might be also a good idea.
