    <p>Well - it's better if you could state what this daemon is supposed to do. As there are specialized frameworks/libraries for various tasks.</p> <p>For simplest daemon that does nothing, just exists, you can easily do this:</p> <pre><code>#!/usr/bin/perl use strict; use warnings; use Carp; use POSIX qw( setsid ); daemonize(); do_your_daemon_stuff(); exit; sub daemonize { chdir '/' or croak "Can't chdir to /: $!"; open STDIN, '/dev/null' or croak "Can't read /dev/null: $!"; open STDOUT, '&gt;/dev/null' or croak "Can't write to /dev/null: $!"; defined(my $pid = fork) or croak "Can't fork: $!"; exit if $pid; setsid or croak "Can't start a new session: $!"; open STDERR, '&gt;&amp;STDOUT' or croak "Can't dup stdout: $!"; } </code></pre> <p>sub daemonize() was liften from <a href="http://perldoc.perl.org/perlipc.html#Complete-Dissociation-of-Child-from-Parent" rel="nofollow noreferrer">perldoc perlipc</a> (with minor change).</p> <p>That's all - the code now properly daemonizes, and can do anything you want.</p> <p>I just read your edit, that you want TCP server.</p> <p>OK. Here is simplistic code:</p> <pre><code>#!/usr/bin/perl use strict; use warnings; use Carp; use POSIX qw( setsid ); use IO::Socket; my $server_port = get_server_port(); daemonize(); handle_connections( $server_port ); exit; sub daemonize { chdir '/' or croak "Can't chdir to /: $!"; open STDIN, '/dev/null' or croak "Can't read /dev/null: $!"; open STDOUT, '&gt;/dev/null' or croak "Can't write to /dev/null: $!"; defined(my $pid = fork) or croak "Can't fork: $!"; exit if $pid; setsid or croak "Can't start a new session: $!"; open STDERR, '&gt;&amp;STDOUT' or croak "Can't dup stdout: $!"; } sub get_server_port { my $server = IO::Socket::INET-&gt;new( 'Proto' =&gt; 'tcp', 'LocalPort' =&gt; 31236, 'Listen' =&gt; SOMAXCONN, 'Reuse' =&gt; 1, ); die "can't setup server" unless $server; return $server; } sub handle_connections { my $port = shift; my $handled = 0; while ( my $client = $port-&gt;accept() ) { $handled++; print $client "Hi, you're client #$handled\n"; chomp ( my $input = &lt;$client&gt; ); my $output = reverse $input; print $client $output, "\n"; print $client "Bye, bye.\n"; close $client; } return; } </code></pre> <p>Just remember that this is blocking tcp server, so it will be able to handle 1 connection at the time. If you want more than 1 - it becomes more complex, and you have to ask yourself if you prefer multithreading (or multi-processing), or you prefer single-process, event based server.</p>

    3. COSo, first - restate your question. Sorry, but I will not guess what you need. Think about what you need, and *try* to write it. I will not write your code for you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
