EXPORTED FUNCTIONS

21   kill($pid, $sig)
22       Will kill the given process id. If $sig is specified it will kill with
23       the given signal.
24
25        task "kill", "server01", sub {
26          kill 9931;
27          kill 9931, -9;
28        };
29
30   killall($name, $sig)
31       Will kill the given process. If $sig is specified it will kill with the
32       given signal.
33
34        task "kill-apaches", "server01", sub {
35          killall "apache2";
36          killall "apache2", -9;
37        };
38
39   ps
40       List all processes on a system. Will return all fields of a ps aux.
41
42        task "ps", "server01", sub {
43          for my $process (ps()) {
44           say "command  > " . $process->{"command"};
45           say "pid    > " . $process->{"pid"};
46           say "cpu-usage> " . $process->{"cpu"};
47          }
48        };
49
50       On most operating systems it is also possible to define custom
51       parameters for ps() function.
52
53        task "ps", "server01", sub {
54          my @list = grep { $_->{"ni"} == -5 } ps("command","ni");
55        };
56
57       This example would contain all processes with a nice of -5.
58
59   nice($pid, $level)
60       Renice a process identified by $pid with the priority $level.
61
62        task "renice", "server01", sub {
63          nice (153, -5);
64        };
