Hi Gerd,
all scripts shipped with TeX Live are using /usr/bin/env on Unix and
nobody complained so far.  I suppose that none of the old Unices you
have in mind is supported by TeX Live for at least more than one or
even two decades and ...

... for Windows there are wrappers anyway.  See


This wrapper is actually a replacement for missing symlinks on
Windows, though it does a little bit more.  Please read the comments
whithin the script if you are interested in the details.

If you add a new script to TeX Live, all you have to do is to add a
shebang line (#!/usr/bin/env <interpreter>) for Unix.  There is no
need to worry about Windows.  The script will be invoked by the
runscript wrapper anyway.

I'm looking forward to meet you at Dante-2018,
