NAME¶
talk
—
talk to another user
SYNOPSIS¶
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.
FILES¶
- /etc/hosts
- to find the recipient's machine
- /var/run/utmp
- to find the recipient's tty
