EXPORTED FUNCTIONS

cron_entry($name, %option) Manage cron entries. cron_entry "reload-httpd", ensure => "present", command => "/etc/init.d/httpd restart", minute => "1,5", hour => "11,23", month => "1,5", day_of_week => "1,3", day_of_month => "1,3,5", user => "root", on_change => sub { say "cron added"; }; # remove an entry cron_entry "reload-httpd", ensure => "absent", command => "/etc/init.d/httpd restart", minute => "1,5", hour => "11,23", month => "1,5", day_of_week => "1,3", day_of_month => "1,3,5", user => "root", on_change => sub { say "cron removed."; }; cron($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"; };
