Here's an improved version.

#! 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"; push @results, $_ while <$fh>; }->detach; sleep 1 until $pid; sleep 1 while kill 0, $pid and $TIMEOUT--; kill 3, $pid and warn 'Command timed out' if $TIMEOUT; print "command return \n'@results'"; __END__ C:\test>timeoutcmd -N=1 command return '1 ' C:\test>timeoutcmd -N=10 command return '1 2 3 4 5 6 7 8 9 10 ' C:\test>timeoutcmd -N=11 Command timed out at C:\test\timeoutcmd.pl line 21. command return '1 2 3 4 5 6 7 8 9 10 11 '
