.Sh SYNOPSIS
|
|
.Nm
|
|
.Ar person
|
|
.Op Ar ttyname
|
|
.Sh DESCRIPTION
|
|
.Nm Talk
|
|
is a visual communication program which copies lines from your
|
|
terminal to that of another user.
|
|
.Pp
|
|
Options available:
|
|
.Bl -tag -width ttyname
|
|
.It Ar person
|
|
If you wish to talk to someone on your own machine, then
|
|
.Ar person
|
|
is just the person's login name. If you wish to talk to a user on
|
|
another host, then
|
|
.Ar person
|
|
is of the form
|
|
.Ql user@host
|
|
or
|
|
.Ql host!user
|
|
or
|
|
.Ql host:user .
|
|
.It Ar ttyname
|
|
If you wish to talk to a user who is logged in more than once, the
|
|
.Ar ttyname
|
|
argument may be used to indicate the appropriate terminal
|
|
name, where
|
|
.Ar ttyname
|
|
is of the form
|
|
.Ql ttyXX .
|
|
.El
|
|
.Pp
|
|
When first called,
|
|
.Nm
|
|
sends the message
|
|
.Bd -literal -offset indent -compact
|
|
Message from TalkDaemon@his_machine...
|
|
talk: connection requested by your_name@your_machine.
|
|
talk: respond with: talk your_name@your_machine
|
|
.Ed
|
|
.Pp
|
|
to the user you wish to talk to.
|
|
At this point, the recipient
|
|
of the message should reply by typing
|
|
.Pp
|
|
.Dl 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
|
|
.Ql ^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;
|
|
.Nm
|
|
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
|
|
.Xr mesg 1
|
|
command. At the outset talking is allowed. Certain commands, in
|
|
particular
|
|
.Xr nroff 1
|
|
and
|
|
.Xr pr 1 ,
|
|
disallow messages in order to
|
|
prevent messy output.
|
