talk address [terminal]
The talk utility is a two-way, screen-oriented communication program.
When first invoked, talk sends a message similar to:
Message from TalkDaemon@ her_machine at time ... talk: connection requested by your_address talk: respond with: talk your_address
to the specified address. At this point, the recipient of the message can reply by typing:
Once communication is established, the two parties can type simultaneously, with their output displayed in separate regions of the screen. Characters are processed as follows:
Permission to be a recipient of a talk message can be denied or granted by use of the mesg(1) utility. However, a user's privilege may further constrain the domain of accessibility of other users' terminals. Certain commands, such as pr(1), disallow messages in order to prevent interference with their output. talk will fail when the user lacks the appropriate privileges to perform the requested action.
Certain block-mode terminals do not have all the capabilities necessary to support the simultaneous exchange of messages required for talk. When this type of exchange cannot be supported on such terminals, the implementation may support an exchange with reduced levels of simultaneous interaction or it may report an error describing the terminal-related deficiency.
The following operands are supported:
host!user host.user host:user user@host
although user@host is perhaps preferred.
See environ(5) for descriptions of the following environment variables that affect the execution of talk: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.
The following exit values are returned:
See attributes(5) for descriptions of the following attributes:

Typing Control-L redraws the screen, while the erase, kill, and word kill characters will work in talk as normal. To exit, type an interrupt character. talk then moves the cursor to the bottom of the screen and restores the terminal to its previous state.
