The docs of IPC::Run 0.96 say kill_kill()
Returns a 1 if the "TERM" was sufficient, or a 0 if "KILL" was
required.
but running the code it is undef and 1 respectively. Sample program
below. The first TERM suffices, the second ignores TERM and needs KILL.
use strict;
use IPC::Run;
foreach my $sh ('sleep 10',
'trap "" TERM; sleep 10') {
my $ipc = IPC::Run::start(['sh','-c',$sh]);
sleep 1;
my $ret = $ipc->kill_kill(grace=>1);
print defined $ret ? $ret : "[undef]", "\n";
}
