7: .TH TALK 1 "November 24, 1987"
8: .UC 5
9: .SH NAME
10: talk \- talk to another user
11: .SH SYNOPSIS
12: .B talk
13: person [ ttyname ]
14: .SH DESCRIPTION
15: \fITalk\fP is a visual communication program which copies lines from your
16: terminal to that of another user.
17: .PP
18: If you wish to talk to someone on your own machine, then \fIperson\fP
19: is just the person's login name. If you wish to talk to a user on
20: another host, then \fIperson\fP is of the form \fIuser@host\fP.
21: .PP
22: If you want to talk to a user who is logged in more than once, the
23: \fIttyname\fP argument may be used to indicate the appropriate terminal
24: name, where \fIttyname\fP is of the form ``ttyXX''.
25: .PP
26: When first called, \fItalk\fP sends the message
27: .PP
28: Message from TalkDaemon@his_machine...
29: talk: connection requested by your_name@your_machine.
30: talk: respond with: talk your_name@your_machine
31: .PP
32: to the user you wish to talk to. At this point, the recipient
33: of the message should reply by typing
34: .PP
35: talk \ your_name@your_machine
36: .PP
37: It doesn't matter from which machine the recipient replies, as
38: long as his login-name is the same. Once communication is established,
39: the two parties may type simultaneously, with their output appearing
40: in separate windows. Typing control L (^L) will cause the screen to
41: be reprinted, while your erase, kill, and word kill characters will
42: behave normally. To exit, just type your interrupt character; \fItalk\fP
43: then moves the cursor to the bottom of the screen and restores the
44: terminal to its previous state.
45: .PP
46: Permission to talk may be denied or granted by use of the \fImesg\fP
47: command. At the outset talking is allowed. Certain commands, in
48: particular \fInroff\fP and \fIpr\fP, disallow messages in order to
49: prevent messy output.
50: .PP
51: .SH FILES
52: /etc/hosts to find the recipient's machine
53: .br
54: /etc/utmp to find the recipient's tty
55: .SH "SEE ALSO"
56: mail(1), mesg(1), who(1), write(1)
57: .SH BUGS
58: The version of \fItalk\fP(1) released with 4.3BSD uses a protocol that
59: is incompatible with the protocol used in the version released with 4.2BSD.
