NAME

       Rex::Commands::Process - Process management commands

DESCRIPTION

       With this module you can manage processes. List, Kill, and so on.

       Version <= 1.0: All these functions will not be reported.

       All these functions are not idempotent.

SYNOPSIS

        kill $pid;
        killall "apache2";
        nice($pid, $level);

EXPORTED FUNCTIONS

   kill($pid, $sig)
       Will kill the given process id. If $sig is specified it will kill with the given signal.

        task "kill", "server01", sub {
          kill 9931;
          kill 9931, -9;
        };

   killall($name, $sig)
       Will kill the given process. If $sig is specified it will kill with the given signal.

        task "kill-apaches", "server01", sub {
          killall "apache2";
          killall "apache2", -9;
        };

   ps
       List all processes on a system. Will return all fields of a ps aux.

        task "ps", "server01", sub {
          for my $process (ps()) {
           say "command  > " . $process->{"command"};
           say "pid    > " . $process->{"pid"};
           say "cpu-usage> " . $process->{"cpu"};
          }
        };

       On most operating systems it is also possible to define custom parameters for ps()
       function.

        task "ps", "server01", sub {
          my @list = grep { $_->{"ni"} == -5 } ps("command","ni");
        };

       This example would contain all processes with a nice of -5.

   nice($pid, $level)
       Renice a process identified by $pid with the priority $level.

        task "renice", "server01", sub {
          nice (153, -5);
        };
