TTY

["Brian K. White" <brian@xxxxxxxxx>]

How can I stop zsh, while in ksh emulation mode, from overwriting $TTY ?

I am setting TTY to the tty without the /dev/ in /etc/profile,
and then I am using that in many places throughout my software in temp file 
names

The stock ksh88 has a bug that my software hits, and I've established that 
neither bash or sh has the same problem, but I have a lot of scripts that 
really need ksh and that I don't want to rewrite.
The ksh93 build system is like a like a Dali painting except without the 
beauty, so, I'm left with pdksh or zsh in ksh emulation. I havn't tried 
pdksh yet and probably don't want it in the long run anyways.
But zsh built without a hitch and doesn't have the bug either.

So, I tried replacing /bin/ksh from my vendors stock ksh88 to zsh for for a 
while and this is pretty much the only thing that broke.
The top level login shell will show the value of TTY that I set, but even 
with export and/or readonly TTY, the sub shells all show the full 
/dev/ttynnn, which breaks all my temp file code.

Thanks
