37 | .Sh NAME | |
38 | .Nm talk | |
39 | .Nd talk to another user | |
40 | .Sh SYNOPSIS | |
41 | .Nm talk | |
42 | .Ar person | |
43 | .Op Ar ttyname | |
44 | .Sh DESCRIPTION | |
45 | .Nm Talk | |
46 | is a visual communication program which copies lines from your | |
47 | terminal to that of another user. | |
48 | .Pp | |
49 | Options available: | |
50 | .Bl -tag -width ttyname | |
51 | .It Ar person | |
52 | If you wish to talk to someone on your own machine, then | |
53 | .Ar person | |
54 | is just the person's login name. If you wish to talk to a user on | |
55 | another host, then | |
56 | .Ar person | |
57 | is of the form | |
58 | .Ql user@host . | |
59 | .It Ar ttyname | |
60 | If you wish to talk to a user who is logged in more than once, the | |
61 | .Ar ttyname | |
62 | argument may be used to indicate the appropriate terminal | |
63 | name, where | |
64 | .Ar ttyname | |
65 | is of the form | |
66 | .Ql ttyXX . | |
67 | .El | |
68 | .Pp | |
69 | When first called, | |
70 | .Nm talk | |
71 | sends the message | |
72 | .Bd -literal -offset indent -compact | |
73 | Message from TalkDaemon@his_machine... | |
74 | talk: connection requested by your_name@your_machine. | |
75 | talk: respond with: talk your_name@your_machine | |
76 | .Ed | |
77 | .Pp | |
78 | to the user you wish to talk to. At this point, the recipient | |
79 | of the message should reply by typing | |
80 | .Pp | |
81 | .Dl talk \ your_name@your_machine | |
82 | .Pp | |
83 | It doesn't matter from which machine the recipient replies, as | |
84 | long as his login-name is the same. Once communication is established, | |
85 | the two parties may type simultaneously, with their output appearing | |
86 | in separate windows. Typing control-L | |
87 | .Ql ^L | |
88 | will cause the screen to | |
89 | be reprinted, while your erase, kill, and word kill characters will | |
90 | behave normally. To exit, just type your interrupt character; | |
91 | .Nm talk | |
92 | then moves the cursor to the bottom of the screen and restores the | |
93 | terminal to its previous state. | |
94 | .Pp | |
95 | Permission to talk may be denied or granted by use of the | |
96 | .Xr mesg 1 | |
97 | command. At the outset talking is allowed. Certain commands, in | |
98 | particular | |
99 | .Xr nroff 1 | |
100 | and | |
101 | .Xr pr 1 , | |
102 | disallow messages in order to | |
103 | prevent messy output. | |
