#{client_tty} maybe or pane_tty. tmux doesn't write to utmp because there is no 
portable way to do it without being setuid or setgid.

Subject: Cannot 'write' to pts because user not logged in 
 
Hello All,

I use 'write' for a number of things, but since I switched to tmux, I can 
no longer write to different terminals.  'write' complains that the use 
I'm trying to send a message isn't logged in on the target terminal.

write: <username> is not logged in on pts/10

One idea is to get tmux to register the pty as a login.  Is that possible?

Another idea is to find out which is the "controlling" pts for the tmux 
client and 'write' to that.  That would be an acceptable workaround...but 
I can't quite figure out how to do it.  I've tried to get tmux to list 
information like #{client_id} using the -F <format> option but I get 
nothing.  So, how can I ask tmux to tell me which terminal a particular 
session is on?  Is that possible?

Thanks,
PMouse
