[server description list]
The ircII/EPIC program is a unix-based character oriented user agent ('client') to Internet
Relay Chat. It is a fully functional ircII client with many useful extensions. This ver-
sion works with all modern irc server classes as of early 1999.
-a Append the server description list to the default server list. The default behavior
is for the server description list to replace the default server list.
-b Operate in so called ``bot mode.'' This implies the [-d] option. EPIC will fork(2)
immediately and the parent process will exit, returning you to your shell. Some sys-
tem administrators do not look kindly to their users running bots, and they have dis-
abled this option. Even if your administrator has not disabled it, you should not
assume this gives you automatic permission to run a bot. If you do run a bot without
permission, your administrator may get very angry with you, and possibly revoke your
account. In addition, most IRC operators on public irc networks have very little tol-
erance for people who run bots. So just a word of caution, make sure that your system
administrator and your irc administrator have given you permission before you run a
-B Force the startup file to be loaded immediately rather than waiting until a connection
to a server is established.
Join the specified channel the first time you successfully connect to a server.
-d Operate in ``dumb mode.'' The client will not put up a full screen display, and will
read from standard input and write to standard output. This is useful if the output
normally looks awful (because you are using an incorrect TERM setting, or your termi-
nal description is spectacularly broken), or you just don't want to use the pretty
interface. This option will be turned on automatically if your current TERM setting
is not capable of a full screen display.
-f Force use of hardware flow control. With this option, the control-S and control-Q
keys are probably not available to be bound to something else.
-F Disable use of hardware flow control. With this option, the control-S and control-Q
keys are available to be bound to something else. However, you will not have hardware
-h Display a moderately concise help message and exit immediately.
Use the IP address of the specified hostname as your default IP address. This can be
used if you have multiple IP addresses on the same machine and you want to use an
address other than the default address. You might need to use this option when
gethostname(3) does not return a hostname (in some poorly configured NIS environ-
ments). The use of multiple IP addresses on a single machine is commonly refered to
as "virtual hosting", and each IP address is a "virtual host". Please understand that
an irc client may not tell the irc server what your hostname should be: the server
alone determines that. Servers typically use the canonical hostname for an IP address
as your hostname. Because of this, this option will not permit you to use a CNAME
(secondary hostname for an IP address), because the server will use the canonical
hostname instead. This option overrides the IRCHOST environment variable.
Use the specified filename(s) as the startup file. The startup file is loaded the
first time you successfully connect to a server, unless you specify the [-B] option.
This overrides the IRCRC environment variable. If this option is not specified, and
the IRCRC environment variable is not set, then ~/.ircrc is the default startup file.
Use the specified nickname as the default nickname whenever you connect to an irc
server. This option overrides the IRCNICK environment variable. This option can be
overriden if you specify nickname argument in the command line (see below).
Use the specified port as the default port for new server connections. The default
port is usually 6667. Make sure that the servers you want to connect to are listening
on this port before you try to connect there.
-q Suppress the loading of any file when you first establish a connection to an irc
-v Output version identification (VID) information and exit.
-x This undocumented feature turns on all of the XDEBUG flags. Refer to the help files
for XDEBUG if you want to know what happens if you use this.
Use the specified username when negotiating a connection to a new irc server. This
overrides the IRCUSER environment variable. If this option is not specified, then the
user name specified in /etc/passwd for your user is used. This feature was formerly
undocumented, but with the rise and popularity and use of identd(8) this option is
much less useful than it once was. Requests to have this option removed will probably
be ignored. If you don't want your users to spoof their usernames, install identd,
and do everyone on IRC a favor.
The first bare word found is taken as the default nickname to use. This overrides all
other options, including the -n option and the IRCNICK environment variable. If all
else fails, then the client uses your login name as the default nickname.
After the nickname, a list of one or more server specifications can be listed. Unless
you specify the -a option, this will replace your default server list! The -a option
forces any servers listed here to be appended to the default server list. The format
for server specifications is:
Any item can be omitted by leaving the field blank, and any trailing colons can also
The screen is split into two parts, separated by an inverse-video status line (if sup-
ported). The upper (larger) part of the screen displays responses from the ircd(8) server.
The lower part of the screen (a single line) accepts keyboard input.
Some terminals do not support certain features required by epic , in which case you receive
a message stating this. If this occurs, try changing the terminal type or run epic with the
Any line beginning with the slash character ``/'' is regarded as an epic command (the com-
mand character may be changed). Any line not beginning with this character is treated as a
message to be sent to the current channel. The client has a built in help system. Install
the help files (they should be available at the same place you got the client) and then type
``/help'' to open up the help system.
The .ircrc File:
When epic 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 charac-
ter ``/'' This allows predefinition of aliases and other features.
Certainly any description of epic in this man page will be sorely inadequate because most of
the confusion doesn't even start until after you get the client to connect to a server. But
if you really have problems getting the client to connect to a server, try some of these:
epic Try this first. This will assume all the defaults. If the person who is maintaining
epic at your site has done a halfway decent job, this will put you on a server that is
somewhat local to you.
epic nickname irc.domain.com
or something similar will attempt to connect to the irc server running on the host
"irc.domain.com" (fill in a real irc server here) with the nickname of well, "nick-
name". This is the most common way to specify an alternate server to use.
epic nickname irc.domain.com:6664
Sometimes, some servers are really busy, and it can take them a long time to establish
a connection with you on the default port (6667). Most major servers on big public
networks accept connections on many different ports, with the most common being most
or all of the ports between 6660 and 6675. You can usually connect much faster if you
use a port other than 6667, if the server you're connecting to supports an alternate
epic nickname irc.efnet.net
If you're totaly stumped and trying to get on efnet, try this.
epic nickname irc.undernet.org
If you're totaly stumped and trying to get on undernet, try this.
epic nickname irc.dal.net
If you're totaly stumped and trying to get on dalnet, try this.
/usr/local/bin/epic the default location of the binary
~/.ircrc default initialization file
~/.irc/ directory you can put your own epic scripts into, that can then be
loaded with /load
/usr/local/share/epic default directory containing message-of-the-day, master initializa-
tion, help files and epic scripts
THE HELP FILES
Starting up the client is the easy part. Once you get connected, you'll probably find you
have no idea what you're doing. That's where the help files come in. If the person who
maintains irc at your site didn't install the help files, pester them until they do. Once
the help files are available, use the ``/help'' command to get started. There are a bazil-
lion commands and a multitude of nuances that will take a few months to get down pat. But
once you do, you will be so firmly addicted to irc that your wife will divorce you, your
kids will leave you, your dog will run away, and you'll flunk all your classes, and be left
to sing the blues.

epic handles the following signals gracefully
SIGUSR1 Closes all DCC connections and EXEC'd processes.
It can be helpful to predefine certain variables in in the ~/.cshrc , ~/.profile , or
IRCNICK The user's default IRC nickname
IRCNAME The user's default IRC realname (otherwise retreieved from /etc/passwd )
IRCSERVER The user's default IRC server list (see server option for details)
HOME Overrides the default home page in /etc/password
TERM The type of terminal emulation to use
Any non-trivial piece of software has bugs. ircII/EPIC is no exception. You can refer to
the KNOWNBUGS file that is distributed with the client source code for a list of problems
that are known to exist and may or may not be fixed some day. If you find a bug that is not
listed there, you can refer to the BUG_FORM file that is also distributed with the source
code. It will give you instructions on how to fill out the report and where to send it.
The online documentation probably should be in docbook form rather than in the current help
format. The entire help system is a hack.
This manual page only describes the options to epic, but doesn't tell you what to do once
you get connected.
