talk
— talk to
another user
talk |
person [ttyname] |
The talk
utility is a visual communication
program which copies lines from your terminal to that of another user.
Options available:
user@host
’ or
‘host!user
’ or
‘host:user
’.ttyXX
’.When first called, talk
sends the
message
Message from TalkDaemon@his_machine... talk: connection requested by your_name@your_machine. talk: respond with: talk your_name@your_machine
to the user you wish to talk to. At this point, the recipient of the message should reply by typing
talk
your_name@your_machine
It does not 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. Typing control-D
‘^D
’ will clear both parts of your
screen to be cleared, while the control-D character will be sent to the
remote side (and just displayed by this talk
client). Your erase, kill, and word kill characters will behave normally. To
exit, just type your interrupt character; talk
then
moves the cursor to the bottom of the screen and restores the terminal to
its previous state.
Permission to talk may be denied or granted by use of the mesg(1) command. At the outset talking is allowed.
The talk
utility relies on the
talkd
system daemon. See
talkd(8) for information about enabling
talkd
.
The talk
command appeared in
4.2BSD.
In FreeBSD 5.3, the default
behaviour of talk
was changed to treat
local-to-local talk requests as originating and terminating at
localhost.
Before this change, it was required that the hostname (as per
gethostname(3)) resolved to a
valid IPv4 address (via
gethostbyname(3)), making
talk
unsuitable for use in configurations where
talkd(8) was bound to the loopback
interface (normally for security reasons).
The version of talk
released with
4.3BSD uses a protocol that is incompatible with the
protocol used in the version released with
4.2BSD.
Multibyte characters are not recognized.
