# write(1)

    NAME
         write - send a message to a logged-in user

    SYNOPSIS
         write [-cv] user [tty]

    OPTIONS

         -c   Use cbreak mode

         -v   Verbose mode

    EXAMPLES

         write ast           # Send a message to ast

         write ast tty00     # Send a message to ast on tty00

    DESCRIPTION

         Write lets a user send messages to another logged-in user. Lines typed by
         the  user appear on the other user's screen a line at a time (a character
         at a time in the case of cbreak mode). The file /usr/adm/wtmp is searched
         to  determine  which tty to send to. If the user is logged onto more than
         one terminal, the tty argument selects the terminal.   Type  CTRL-  D  to
         terminate the command.  Use ! as a shell escape.
