     NAME
          write - write to another user

     SYNOPSIS
          write user [ line ]

     DESCRIPTION
          Write copies lines from your terminal to that of another
          user.  When first called, it sends this message to the
          person you want to talk to:

               Message from yourname (tty??)  [ date ]...

          When it has successfully completed the connection, write
          also sends two bells to your own terminal to indicate that
          what you are typing is being sent.

          The recipient of the message should write back at this
          point.  Communication continues until an end of file is read
          from the terminal, an interrupt is sent, or the recipient
          has executed "mesg n."  At that point, write writes EOT on
          the other terminal and exits.

          If you want to write to a user who is logged in more than
          once, use the line argument to indicate which line or
          terminal to send to (e.g., tty00); otherwise, the first
          writable instance of the user found in /etc/utmp is assumed
          and the following message posted:

               user is logged on more than one place.
               You are connected to "terminal".
               Other locations are:
               terminal

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

          If the character ! is found at the beginning of a line,
          write calls the shell to execute the rest of the line as a
          command.

          We suggest the following protocol for using write:  when you
          first write to another user, wait for them to write back
          before starting to send.  Each person should end a message
          with a distinctive signal (e.g., o for "over") so that the
          other person knows when to reply.  The signal oo (for "over
          and out") is useful when you're terminating the
          conversation.

     DIAGNOSTICS
          user is not logged on
                 The person you are trying to

                 write to is not logged on.

          Permission denied
                 The person you are trying to write to denies that
                 permission (with mesg).

          Warning: cannot respond, set mesg -y
                 Your terminal is set to mesg n, therefore the
                 recipient cannot respond to you.

          Can no longer write to user
                 The recipient has denied permission (mesg n) after
                 you have started writing.
