NAME

       write - interactively write (talk) to another user

SYNOPSIS

DESCRIPTION

       The command copies lines from your terminal to that of another user.  When first called, it sends the message:

       to the receiving user's terminal.  When it has successfully completed the connection, it also sends two bells to your own terminal to indi-
       cate that what you are typing is being sent.

       To set up two-way communication, the recipient of the message (user) must execute the command:

       (yourterminal is only required if the originator is logged in more than once.)

       Communication continues until an end of file is read from the terminal, an interrupt is sent, or the  recipient	executes  At  that  point,
       writes on the other terminal and exits.

       To  write  to a user who is logged in more than once, use the terminal argument to indicate which line or terminal to send to (e.g., Other-
       wise, the first writable instance of the user found in database is assumed and the following message is displayed:

	      terminal
	      ...

       Permission to write may be denied or granted with the command (see mesg(1)).  Writing to others is normally allowed  by	default.   Certain
       commands, in particular and disallow messages in order to prevent interference with their output.  However, if the user has the appropriate
       privileges, messages can be forced onto a write-inhibited terminal.

       If the character is found at the beginning of a line, calls the POSIX shell (see sh-posix(1)) to execute the rest of the line as a command.

       The following protocol is suggested for using When you first to another user, wait for the user to back before starting to send.  Each per-
       son  should  end  a message with a distinctive signal (such as "" for "over") so that the other person knows when to reply.  Similarly, the
       signal "" (for "over and out") can be used to indicate the end of the conversation.

EXTERNAL INFLUENCES

   Environment Variables
       determines the locale to use for the locale categories when both and the corresponding environment variable (beginning with do not  specify
       a locale.  If is not set or is set to the empty string, a default of "C" (see lang(5)) is used.

       determines the format and contents of date and time strings.

       determines the language in which messages are displayed.

       If  any	internationalization  variable	contains an invalid setting, behaves as if all internationalization variables are set to "C".  See
       environ(5).

   International Code Set Support
       Single- and multi-byte character code sets are supported.

DIAGNOSTICS

       The user you are trying to write to is not logged on.

       Your correspondent has denied write permission
	      after your session started.  Your session is ended.

       Your correspondent sent end-of-file,
	      or you set your terminal to and your correspondent tried to write to you.  If you have a session established, you  can  continue	to
	      write to your correspondent.

       The user you are trying to write to has denied write permission (with

       Your terminal is set to
	      and the recipient cannot respond to you.

EXAMPLES

       By issuing the command:

       user sends a message to user screen.  If responds:

       two-way communication between and is established.
