This worked for me. I used 'apt' instead:
#!/usr/bin/perl
use strict;
use warnings;
use Daemon::Generic;
my $sleeptime = 1
newdaemon(
progname => 'apt',
pidfile => '/var/run/apt.conf.pid',
configfile => '/etc/apt.conf',
);
sub gd_preconfig
{
my ($self) = @_;
open(CONFIG, "</etc/apt.conf")
while <CONFIG>;
close(CONFIG);
return ();
}
sub gd_run
{ while (1) {
sleep($sleeptime);
print scalar(localtime(time))."\n";
}
}
Note: I didn't use foreground. It went into an infinite loop. Use:
perl myscript.pl start, then
perl myscript.pl check. It'll give a pid number.
