Daemonise.pl

1. Get list of running peers
2. for ( `ps x` ) { push @peers, [$2,$1,$3] if /^\s*(\d+).+?peerd \((.*):(.*)\)/ }

1. Get status of all running peers

if ( exists $config{ remove } ) { }

1. Install the service
2. - install a shell cmd into init.d and links to it in rc[2-5].d

if ( exists $config{ install } ) {

# check if peer of this name/port not already running

my $icmd = $cmd; my $fn = "$daemon-".lc $peer; $icmd =~ s/install/start/; writeFile my $target = "/etc/init.d/$fn.sh", "#!/bin/sh\n$icmd\n"; symlink $target, "/etc/rc$_.d/S09$fn" for 2..5; }

1. Remove the named service and exit
2. - remove shell script from init.d and links from rc[2-5].d

if ( exists $config{ remove } ) { my $fn = "$daemon-".lc $peer; unlink "/etc/rc$_.d/S09$fn" for 2..5; unlink "/etc/init.d/$fn.sh"; }

1. Start as a daemon
2. - see http://www.webreference.com/perl/tutorial/9 for help on daemons in PERL
