|
|
.SH NAME
|
|
talk \- talk to another user
|
|
.SH SYNOPSIS
|
|
.B talk
|
|
person [ ttyname ]
|
|
.SH DESCRIPTION
|
|
\fITalk\fP is a visual communication program which copies lines from your
|
|
terminal to that of another user.
|
|
.PP
|
|
If you wish to talk to someone on your own machine, then \fIperson\fP
|
|
is just the person's login name. If you wish to talk to a user on
|
|
another host, then \fIperson\fP is of the form \fIuser@host\fP.
|
|
.PP
|
|
If you want to talk to a user who is logged in more than once, the
|
|
\fIttyname\fP argument may be used to indicate the appropriate terminal
|
|
name, where \fIttyname\fP is of the form ``ttyXX''.
|
|
.PP
|
|
When first called, \fItalk\fP sends the message
|
|
.PP
|
|
Message from TalkDaemon@his_machine...
|
|
talk: connection requested by your_name@your_machine.
|
|
talk: respond with: talk your_name@your_machine
|
|
.PP
|
|
to the user you wish to talk to. At this point, the recipient
|
|
of the message should reply by typing
|
|
.PP
|
|
talk \ your_name@your_machine
|
|
.PP
|
|
It doesn't matter from which machine the recipient replies, as
|
|
long as his login-name is the same. Once communication is established,
|
|
the two parties may type simultaneously, with their output appearing
|
|
in separate windows. Typing control L (^L) will cause the screen to
|
|
be reprinted, while your erase, kill, and word kill characters will
|
|
behave normally. To exit, just type your interrupt character; \fItalk\fP
|
|
then moves the cursor to the bottom of the screen and restores the
|
|
terminal to its previous state.
|
|
.PP
|
|
Permission to talk may be denied or granted by use of the \fImesg\fP
|
|
command. At the outset talking is allowed. Certain commands, in
|
|
particular \fInroff\fP and \fIpr\fP, disallow messages in order to
|
|
prevent messy output.
|
|
.PP
|
|
.SH FILES

|
|
is incompatible with the protocol used in the version released with 4.2BSD.
