NAMERex::Commands::Process − Process management commands
DESCRIPTIONWith 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;
};
psList 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);
};
