EXPORTED FUNCTIONS
cron_entry($name, %option)Manage cron entries. cron_entry "reload−httpd",
ensure => "present",
command => "/etc/init.d/httpd restart",
minute => "1,5",
hour => "11,23",
month => "1,5",
day_of_week => "1,3",
day_of_month => "1,3,5",
user => "root",

# remove an entry
cron_entry "reload−httpd",
ensure => "absent",
command => "/etc/init.d/httpd restart",
minute => "1,5",
hour => "11,23",
month => "1,5",
day_of_week => "1,3",
day_of_month => "1,3,5",
user => "root",
on_change => sub { say "cron removed."; };
cron($action => $user, ...)With this function you can manage cronjobs. List cronjobs. use Rex::Commands::Cron;
use Data::Dumper;
task "listcron", "server1", sub {
my @crons = cron list => "root";
print Dumper(\@crons);
};
Add a cronjob. This example will add a cronjob running on minute 1, 5, 19 and 40. Every hour and every day. use Rex::Commands::Cron;
use Data::Dumper;
task "addcron", "server1", sub {
cron add => "root", {
minute => "1,5,19,40",
command => '/path/to/your/cronjob',
};
};
This example will add a cronjob running on the 1st, 3rd and 5th day of January and May, but only when it's a Monday or Wednesday. On those days, the job will run when the hour is 11 or 23, and the minute is 1 or 5 (in other words at 11:01, 11:05, 23:01 and 23:05). task "addcron", "server1", sub {
cron add => "root", {
minute => "1,5",
hour => "11,23",
month => "1,5",
day_of_week => "1,3",
day_of_month => "1,3,5",
command => '/path/to/your/cronjob',
};
};
Delete a cronjob. This example will delete the 4th cronjob. Counting starts with zero (0). task "delcron", "server1", sub {
cron delete => "root", 3;
};
Managing Environment Variables inside cron. task "mycron", "server1", sub {
cron env => user => add => {
MYVAR => "foo",
};
cron env => user => delete => $index;
cron env => user => delete => 1;
cron env => user => "list";
};
