       write - interactively write (talk) to another user

       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

       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:


       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 appropri‐
       ate 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 person
       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  conversa‐

   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

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

       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 con‐
	      tinue to write to your correspondent.

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