TALK(1)			  BSD General Commands Manual		       TALK(1)

NAME
     talk -- talk to another user

SYNOPSIS
     talk person [ttyname]

DESCRIPTION
     Talk is a visual communication program which copies lines from your ter-
     minal 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' or `pts/X'.

     When first	called,	talk contacts the talk daemon on the other user's ma-
     chine, which 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	that user. At this point, he then replies 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; their output will	appear in separate
     windows.  Typing control-L	(^L) will cause	the screen to be reprinted.
     The erase,	kill line, and word erase characters (normally ^H, ^U, and ^W
     respectively) will	behave normally.  To exit, just	type the interrupt
     character (normally ^C); talk then	moves the cursor to the	bottom of the
     screen and	restores the terminal to its previous state.

     As	of netkit-ntalk	0.15 talk supports scrollback; use esc-p and esc-n to
     scroll your window, and ctrl-p and	ctrl-n to scroll the other window.
     These keys	are now	opposite from the way they were	in 0.16; while this
     will probably be confusing	at first, the rationale	is that	the key	combi-
     nations with escape are harder to type and	should therefore be used to
     scroll one's own screen, since one	needs to do that much less often.

     If	you do not want	to receive talk	requests, you may block	them using the
     mesg(1) command.  By default, talk	requests are normally not blocked.
     Certain commands, in particular nroff(1), pine(1),	and pr(1), may block
     messages temporarily in order to prevent messy output.

FILES
     /etc/hosts	    to find the	recipient's machine
     /var/run/utmp  to find the	recipient's tty

SEE ALSO
     mail(1), mesg(1), who(1), write(1), talkd(8)

BUGS
     The protocol used to communicate with the talk daemon is braindead.

     Also, the version of talk(1) released with	4.2BSD uses a different	and
     even more braindead protocol that is completely incompatible. Some	vendor
     Unixes (particularly those	from Sun) have been found to use this old pro-
     tocol.

     Old versions of talk may have trouble running on machines with more than
     one IP address, such as machines with dynamic SLIP	or PPP connections.
     This problem is fixed as of netkit-ntalk 0.11, but	may affect people you
     are trying	to communicate with.

HISTORY
     The talk command appeared in 4.2BSD.
