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

By editing the source code and recompiling. Approximately line 720 in
Src/params.c.
The following variables are unconditionally set regardless of emulation:
BAUD
CPUTYPE
FCEDIT
HOST
KEYTIMEOUT
LISTMAX
LOGCHECK
LOGNAME
MACHTYPE
MAILCHECK
OSTYPE
TIMEFMT
TMPPREFIX
TTY
VENDOR
WATCHFMT
ZSH_NAME
ZSH_VERSION
signals
