NAME
ircII — interface to the Internet Relay Chat system

SYNOPSIS
irc [-abdFfqrSsTtv] [-c chan] [-D level] [-e protocol level] [-H host[:port]] [-h host[:port]]
[-I ircrcquick] [-icb] [-irc] [-l ircrc] [-o file] [-P portno] [-p portno] [-R host[:port]]
[nickname [server list]] [--]

DESCRIPTION
The ircII program is a full screen, termcap based interface to Internet Relay Chat. It gives
full access to all of the normal IRC functions, plus a variety of additional options.

OPTIONS
The following options are supported:

-a This adds the normal irc server list to the command line list of irc
servers.

-b Load the .ircrc file before connection to a server, not afterwards.

-c chan Automatically join channel chan.

-d Start in non-full screen mode. All input is taken directly from stdin and
all output goes to stdout without using any of the termcap(5) screen con‐
trol codes.

-D level Enable debugging of level. This option is only available if ircII is built
with -DDEBUG.

-e protocol level For protocol protocol, set the default encryption (SSL) level to level.
Currently, only "IRC" is supported for the protocol and the values that
level can take are "check", "nocheck", and "off". Please also see the de‐
scription of the "server list" below.

-F Don't use flow control (^S and ^Q) to stop start the display. This switch
is ignored if the -d switch is used.

-f Use flow control (^S and ^Q) to stop/start the display. Normally these are
both bound to other functions within ircII. This switch is ignored if the
-d switch is used.

-H host[:port] This option instructs ircII to use the given host as the local address for
DCC, and works otherwise identically to the -h option.

-h host[:port] This option instructs ircII to use the given host as the local address.
Useful only on multi-homed hosts. If the optional port segment is in‐
cluded, ircII will attempt to bind to this local port as well as local host
address. If host is an IPv6 "number", it must be provided in the common
file ... [12:34:ab:cd] format. This means for an IPv6 "number" and port,
it would be written [12:34:ab:cd]:6669.

-icb Use ICB connections by default.

-irc Use IRC connections by default.

-l ircrc Use ircrc Instead of the default ~/.ircrc.

-o file Set the debug output file to file. This option is only available if ircII
is built with -DDEBUG.

-P portno Set the ICB port number to portno (default: 7326, the standard ICB port).

-p portno Set the IRC port number to portno (default: 6667, the standard IRC port).
Only supply this if you connect to a server which uses a port other than
6667.

-q Start up ircII quickly. Don't load the IRCRC file, only the quick IRCRC
file set by the

-I option.

-R host[:port] Set the default HTTP proxy host for server connections to host:port.

-r Reverse the normal default foreground and background colours.

-S Start up the ircio process to connect to the IRC server.

-s Don't start up the ircio process to connect to the IRC server (default).

-T Do use the termcap ti and te sequences when starting and exiting if they
exist.

-t Don't use the termcap ti and te sequences when starting and exiting (de‐
fault).

-v Print the version and release date of ircII and exit.

-- End all option processing.

The remaining command line arguments are:

•• nickname Set the nickname (overrides the environment variable IRCNICK; default: the user‐
name).

•• server list Set the list of servers with which ircII will try to connect upon startup.
This list is also used by the program's /server command.

For IRC connections, the format is: host[:portno[:password[:nick]]]

For ICB connections, the format is: ICB/host [:portno[:nick[:group[:mode]]]] with group being
the initial group and mode being the initial group mode. See /HELP ICB for more information
about ICB.

If the host is in the format :servergroup:host.com then servergroup is taken to be the Server
Group for this server entry.

If the host is prefixed with SSLIRC/ or SSLIRCNOCHECK/ then an attempt will be made to initiate
an SSL/TLS connection for this host. The SSLIRCNOCHECK/ form does not verify the remote
server's certificate, which may have security implications. Please see SSL/TLS documentation
for more information.

If the host is prefixed with PROXY/host:port/ then this server will be connected via specified
HTTP proxy server. The NO_PROXY/ prefix will disable any global proxy setting for this server.

DETAILED DESCRIPTION
The Screen
The screen is split into two parts, separated by an inverse-video status line (if supported).
The upper (larger) part of the screen displays responses from the IRC server. The lower part
of the screen (a single line) accepts keyboard input.

Some terminals do not support certain features required by ircII, in which case you receive a
message stating this. If this occurs, try changing the terminal type or run ircII with the -d
option.

IRC Commands
Any line beginning with the slash character (‘/’) is regarded as an ircII command (the command
character may be changed; type /help set cmdchar). Any line not beginning with this character
is treated as a message to be sent to the current channel. To produce a listing of commands,
type /help ?. To receive information about the commands type /help <command>.

The .ircrc File
When ircII is executed, it checks the user's home directory for a .ircrc file, executing the
commands in the file. Commands in this file do not need to have a leading slash character
(‘/’). This allows predefinition of aliases and other features.

ENVIRONMENT
It can be helpful to predefine certain variables in in the .cshrc, .profile, or .login file:

IRCNICK The user's ircII nickname.

IRCNAME The user's IRC realname (otherwise retrieved from /etc/passwd)

IRCSERVER The default IRC server(s) (see server option for details)

IRCSERVERSFILE
The file containing the default list of server(s), usually
PREFIX/share/irc/ircII.servers. This file should contain one server entry per
line.

HOME Overrides the default home path in /etc/passwd.

TERM The type of terminal in use.

FILES
~/.ircrc default initialization file

~/.irc/ directory into which you can put your own ircII scripts, that can then be
loaded with /load

.../share/irc/ directory containing message-of-the-day, master initialization, help
files, and ircII scripts

.../share/irc/script/global
file loaded at the start of every ircII session.

PREFIX/share/irc/ircII.servers
The initial list of servers if none are provided on the command line.

PREFIX/share/irc/ircII.motd
Message of the day. This file is displayed only once each time it is
changed.

EXAMPLES
irc -c #users -p 5555
Connect IRC to port number 5555 of the default host and enter on channel #users.
irc Mermaid
Use the nickname “Mermaid”.
irc Mermaid server1:5000 server2::passwd server3
Use the nickname “Mermaid” and the modified server list.
irc piglet3 :ln:irc1.lamenet.org :ln:irc.us.lamenet.org
Use the nickname “piglet3”, initially connecting to irc.au.lamenet.org, with also
irc.us.lamenet.org added to the server list, both having a server group name “ln”.
irc oink ICB/www.icb.net
Use the nick “oink” making an ICB connection to www.icb.net.
irc -d
Use dumb mode.
irc -f
Allow use of ^S/^Q to stop/start screen display.
irc -e elisa
Interface IRC with a program called “elisa”.

setenv IRCNICK Mermaid
setenv IRCNAME
irc
Set the username (if not specified elsewhere) to “Mermaid”. The user's name (when provided in‐
side parentheses in response to a WHOIS command) is set to “The one and only :)”.

THE HELP FILES
All of the ircII commands are fully described in the help files package. The best way to start
here is with the /HELP ? command as this prints a listing of all available help files.

SIGNALS
ircII handles the following signals

SIGUSR1 Closes all DCC connections and EXEC'ed processes.

SIGUSR2 Drops ircII back to the command line.
