Schedule::Cron never returns to main script

I am trying to run a Perl script (test.pl) once every minute without using crontab. Since I will not have access to write cron jobs into /etc/cron.d/, I am using the Perl module Schedule::Cron.

I have included the code for test.pl in a script that is running continuously and given code like:

my $cron = new Schedule::Cron(sub {}); 
$cron->add_entry("* * * * *",\&test_function); 
$cron->run(nofork=>1)

The issue is that the line

$cron->run(nofork=>1)

never returns back to the main script, and it is not executing any code that are given after that.

I need a solution for this to run cron in the background (using Schedule::Cron) and then return back to the main script for executing the remaining script.

Solution

  • Change:

    $cron->run(nofork=>1)

    to:

    $cron->run(detach=>1)

    This returns immediately to the main script. From Schedule::Cron (detach):

    If set to a true value the scheduler process is detached from the current process (UNIX only).
