How do I run a shell command in a while loop?

The command is:

Code:
sic -h irc.freenode.net 2>&1 | tee -a irc.log

Where sic is an IRC client, and I'm piping the output to tee in order to log my IRC sessions.

I'm trying to handle reconnects by running it in a while loop in the shell process and cat the initial commands into sic's stdin.

I would think to approach this by using a fifo (using the mkfifo(1) command) to redirect sic's stdin, but I'm not sure if there's a more elegant way to reconnect on ping timeouts, kills, servers going down, and just disconnects in general.

How do you suggest I go about doing this?

(I'm using OpenBSD's ksh if that matters.)

NAME
POE::Component::IRC::Plugin::CTCP - A PoCo-IRC plugin that auto-responds to CTCP requests SYNOPSIS
use strict; use warnings; use POE qw(Component::IRC Component::IRC::Plugin::CTCP); my $nickname = 'Flibble' . $$; my $ircname = 'Flibble the Sailor Bot'; my $ircserver = 'irc.blahblahblah.irc'; my $port = 6667; my $irc = POE::Component::IRC->spawn( nick => $nickname, server => $ircserver, port => $port, ircname => $ircname, ) or die "Oh noooo! $!"; POE::Session->create( package_states => [ main => [ qw(_start) ], ], ); $poe_kernel->run(); sub _start { # Create and load our CTCP plugin $irc->plugin_add( 'CTCP' => POE::Component::IRC::Plugin::CTCP->new( version => $ircname, userinfo => $ircname, )); $irc->yield( register => 'all' ); $irc->yield( connect => { } ); return: } DESCRIPTION
POE::Component::IRC::Plugin::CTCP is a POE::Component::IRC plugin. It watches for "irc_ctcp_version", "irc_ctcp_userinfo", "irc_ctcp_ping", "irc_ctcp_time" and "irc_ctcp_source" events and autoresponds on your behalf. METHODS
"new" Takes a number of optional arguments: 'version', a string to send in response to "irc_ctcp_version". Default is PoCo-IRC and version; 'clientinfo', a string to send in response to "irc_ctcp_clientinfo". Default is <http://search.cpan.org/perldoc?POE::Component::IRC::Plugin::CTCP>. 'userinfo', a string to send in response to "irc_ctcp_userinfo". Default is 'm33p'; 'source', a string to send in response to "irc_ctcp_source". Default is http://search.cpan.org/dist/POE-Component-IRC <http://search.cpan.org/dist/POE-Component-IRC>. 'eat', by default the plugin uses PCI_EAT_CLIENT, set this to 0 to disable this behaviour; Returns a plugin object suitable for feeding to POE::Component::IRC's "plugin_add" method. "eat" With no arguments, returns true or false on whether the plugin is "eating" CTCP events that it has dealt with. An argument will set "eating" to on or off appropriately, depending on whether the value is true or false. AUTHOR
