NAME

talktalk to another user

SYNOPSIS

talk [-Hs] person [ttyname]

DESCRIPTION

talk is a visual communication program which copies lines from your terminal to that of another user.
The command arguments are as follows:
 
 
-H
Don't escape characters with the high bit set. This may be useful for certain character sets, but could cause erratic behaviour on some terminals.
 
 
-s
Use smooth scrolling in the talk window. The default is to clear the next two rows and jump from the bottom of the window to the top.
 
 
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 Talk_Daemon@localhost... 
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 the login name is the same. If the machine is not the one to which the talk request was sent, it is noted on the screen. 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 the erase, kill, and word kill characters will behave normally. To exit, just type the 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, such as pr(1), disallow messages in order to prevent messy output.

ASYNCHRONOUS EVENTS

The flags [-Hs] are extensions to that specification.
