Thanks Bart. 

That's cool. However this gives one PS1 prompt as extra output. So I
have to set PS1='' before I call zsh and then set PS1 inside the
payload script.

Demo: Create the setup file

% cat >/tmp/setup <<END
PS1='>>> '
date
date
xxxx () { echo "hello"; }
END

Run zsh - added -f to ignore my start up files

% zsh -fis <<<"source /tmp/setup </dev/tty && exec </dev/tty"

>>> xxxx                                                                        
hello
>>>                                                                             

See the extra "teapot% " prompt that sneaks in. Instead run

PS1='' zsh -fis <<<"source /tmp/setup </dev/tty && exec </dev/tty"

and it does the desired thing. Brilliant.

		Anthony. :-)
