|

.SH DESCRIPTION
|
||||
.I Ircsrv
|
||||
makes a connection to an irc server and reconnects if the connection
|
||||
gets broken. It posts a service to /srv and creates (if necessary) an
|
||||
append mode log file to /tmp. Default file and service name is a
|
||||
concatenation of 4 first letters of username and the string
|
||||
.I irc
|
||||
.
|
||||
.PP
|
||||
.I Irc
|
||||
is a client program that makes use of the service provided by
|
||||
.I ircsrv
|
||||
and provides a user interface for sending and receiving
|
||||
messages.
|
||||
.PP
|
||||
The command language understood by
|
||||
.I irc
|
||||
is as follows
|
||||
.EX
|
||||
/h this message
|
||||
/H this message
|
||||
/m privmsg #chan/nick message
|
||||
/M mode #chan +nt
|
||||
/j join [ #chan ]
|
||||
/p part [ #chan ]
|
||||
/q send parameters raw to the server
|
||||
/l list [ #chan ]
|
||||
/n nick newnick
|
||||
/N notice #chan/nick message
|
||||
/t set [ victim ]
|
||||
/T topic [ #chan [ newtopic ]]
|
||||
/W whois nick
|
||||
/w who nick (a shorter whois)
|
||||
.EE
|
||||
.PP
|
||||
The
|
||||
.I -e
|
||||
flag enables SSL, the
|
||||
.I -c
|
||||
flag sets character set conversion using
|
||||
.IR tcs (1),
|
||||
the
|
||||
.I -r
|
||||
flag will cause irc to replay the conversation from the raw file supplied as argument without user interaction,
|
||||
the
|
||||
.I -b
|
||||
flag causes the client to display the last n lines of the default target or
|
||||
conversations if no target is set. Without any arguments
|
||||
.I -b
|
||||
prints the conversation from the very beginning.
|
||||
The
|
||||
.I -t
|
||||
flag sets the default target to which the messages are
|
||||
sent by default if a line written to
|
||||
.I irc
|
||||
does not begin with /. Irc also prints messages to/from
|
||||
the target exclusively if one is set. Irc prints only private messages if the target is set to "MSGS", useful for being notified when a message is sent to your nick without having to monitor all the status information.
|
||||
.SH EXAMPLES
|
||||
To start up ircsrv on a remote cpu server
|
||||
.EX
|
||||
cpu -c ircsrv glenda irc.freenode.net
|
||||
.EE
|
||||
.PP
|
||||
To use ircsrv started earlier on a cpu server
|
||||
.EX
|
||||
import $cpu /srv
|
||||
import $cpu /tmp
|
||||
irc
|
||||
.EE
|
||||
.PP
|
||||
To start/see/continue a conversation with a specific target (can be #chan or nick)
|
||||
.EX
|
||||
irc -t \'#plan9\'
|
||||
irc -t f2f
|
||||
.EE
|
||||
.PP
|
||||
To run irc within acme start irc inside
|
||||
"win -e":
|
||||
.EX
|
||||
win -e
|
||||
irc -t f2f
