+.Sh NAME
+.Nm write
+.Nd send a message to another user
+.Sh SYNOPSIS
+.Nm
+.Ar user
+.Op Ar ttyname
+.Sh DESCRIPTION
+.Nm
+allows you to communicate with other users, by copying lines from
+your terminal to theirs.
+.Pp
+When you run the
+.Nm
+command, the user you are writing to gets a message of the form:
+.Pp
+.Dl Message from yourname@yourhost on yourtty at hh:mm ...
+.Pp
+Any further lines you enter will be copied to the specified user's
+terminal.
+If the other user wants to reply, they must run
+.Nm
+as well.
+.Pp
+When you are done, type an end-of-file or interrupt character.
+The other user will see the message
+.Ql EOF
+indicating that the
+conversation is over.
+.Pp
+You can prevent people (other than the super-user) from writing to you
+with the
+.Xr mesg 1
+command.
+Some commands, for example
+.Xr nroff 1
+and
+.Xr pr 1 ,
+disallow writing automatically, so that your output isn't overwritten.
+.Pp
+If the user you want to write to is logged in on more than one terminal,
+you can specify which terminal to write to by specifying the terminal
+name as the second operand to the
+.Nm
+command.
+Alternatively, you can let
+.Nm
+select one of the terminals \- it will pick the one with the shortest
+idle time.
+This is so that if the user is logged in at work and also dialed up from
+home, the message will go to the right place.
+.Pp
+The traditional protocol for writing to someone is that the string
+.Ql \-o ,
+either at the end of a line or on a line by itself, means that it's the
+other person's turn to talk.
+The string
+.Ql oo
+means that the person believes the conversation to be
+over.
