TALK(1) General Commands Manual TALK(1)
talk - talk to another user
talk username [ ttyname ]
talk is a visual communication program which copies lines from your
terminal to that of another user.
If you wish to talk to someone on your own machine, then username is
just the person's login name. If you wish to talk to a user on another
host, then username is one of the following forms :
though user@host is perhaps preferred.
If you want to talk to a user who is logged in more than once, the tty-
name argument may be used to indicate the appropriate terminal name.
When first called, talk sends the message:
Message from TalkDaemon@his_machineattime...
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:
example% talk your_name@your_machine
It does not matter from which machine the recipient replies, as long as
their login name is the same. Once communication is established, the
two parties may type simultaneously, with their output appearing in
separate windows. Typing CTRL-L redraws the screen, while your erase,
kill, and word kill characters will work in talk as normal. To exit,
just type your interrupt character; talk then moves the cursor to the
bottom of the screen and restores the terminal.
Permission to talk may be denied or granted by use of the mesg command.
At the outset talking is allowed. Certain commands, in particular
nroff(1) and pr(1V) disallow messages in order to prevent messy output.
