Daemonise.pl

1. Install the service into init.d and rc2-5.d

if ( exists $config{ install } ) { # todo: check if peer of this name/port not already running my $fn = "$::daemon-".lc $::peer; writeFile my $target = "/etc/init.d/$fn.sh", "#!/bin/sh\n/usr/bin/perl $::dir/$::daemon $::peer --start --dir=$::dir/ --port=$::port\n"; symlink $target, "/etc/rc$_.d/S99$fn" for 2..5; chmod 0755, "$fn.sh"; logAdd "$fn.sh added to /etc/init.d"; }

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/S99$fn" for 2..5; unlink "/etc/init.d/$fn.sh"; logAdd "$fn.sh removed from /etc/init.d"; }

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