Rex::Commands::Process - Process management commands

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.

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

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;
 };

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;
 };

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.

Renice a process identified by $pid with the priority $level.

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