T'is easy with a thread:

#! perl -slw use strict; use threads; use threads::shared; $|++; our $N ||= 11; my $TIMEOUT = 10; my $extApp = q[ perl -lwe"$|++; print $_ and sleep 1 for 1 .. $ARGV[0] +" ]; my @results :shared; my $pid :shared; async { $pid = open my $fh, "$extApp $N |" or die "$!, $^E"; @results = <$fh>; }->detach; kill 0, $pid while sleep 1 and $TIMEOUT--; kill 3, $pid and warn 'Command timed out' if $TIMEOUT; print "command return \n'@results'"; __END__ c:\test>junk6 -N=8 command return '1 2 3 4 5 6 7 8 ' c:\test>junk6 -N=10 command return '1 2 3 4 5 6 7 8 9 10 ' c:\test>junk6 -N=12 Command timed out at c:\test\ line 21. command return '1 2 3 4 5 6 7 8 9 10 11 '

Wrapping that into a sub is left as an exercise.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

      Should cpanminus be part of the standard Perl release?
