Sure. Oh the compatibility of shells i meant, of course. But
that mostly colours, now that ~/.profile ensures HOSTNAME and
LOGNAME per se. No more \XY escapes here, except \e and the
\[..\] that some need (to get it column counting right, with
colours) (SHTYPE=bash and =yash).
And the "set -o" you need/can to get where you want to be, ksh for
example braceexpand, emacs-usemeta (if possible), expand_aliases
(bash), cdprint/emacs/tabcomplete (NetBSD ksh).
It is of course all a bitrot-affine compatibility mess. You look
for $0, sometimes deeper for some *_VERSION, for $OSTYPE (which my
~/.profile sets, too). But in the end it is all a mess. If
i recall correctly i once proposed a standardized VERSION or xy
thing so that one could easily identify, even in subshells. But
that would affect future shells only, anyhow. At one time i have
thrown away a lot of tests, since fish and some other shells
i will never use no more, what remains is just enough to start
working the best i can with dash, bash, ksh. Last change on PS1
in March 2018, i usually only have one account per $HOSTNAME.
Pretty bitter is shells without aliases, where the a-lia-ses have
to be created as sh_ell_functions. And then one says builtin, the
other says built-in.
Yeah i mean computing would be nice, if there would not be those
uncountable quirks you need in real life. The maintainer of
libinput has written a short down-to-earth article on that a few
years ago.
That reminds me of my bitter gut feeling that something bad will
happen, all these days, but luckily the rocket that carried some
real penis lifted successfully.
