NAME
talk

talk to another user
SYNOPSIS
talk |
person [ttyname] |
DESCRIPTION
talk
is a visual communication program which copies
lines from your terminal to that of another user.
Options available:
- person
- If you wish to talk to someone on your own machine, then
person is just the person's login name. If you wish
to talk to a user on another host, then person is of
the form ‘
user@host
’. - ttyname
- If you wish to talk to a user who is logged in more than once, the
ttyname argument may be used to indicate the
appropriate terminal name, where ttyname is of the
form ‘
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 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; 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. Certain commands, in particular nroff(1) and pr(1), disallow messages in order to prevent messy output.
ENVIRONMENT
If the TALKHOST
environment variable is
set, its value is used as the hostname the
talk
packets appear to be originating from. This is
useful if you wish to talk to someone on another machine and your internal
hostname does not resolve to the address of your external interface as seen
from the other machine.
FILES
- /etc/hosts
- to find the recipient's machine
- /var/run/utmp
- to find the recipient's tty

4.2BSD.
