There's pdksh, which AFAIK is a pretty good clone of the POSIX ksh
(I've read there are some problems, but don't know exactly what they
are). It uses much less memory, has 90% of the features, and in some
simplistic tests I've done, runs about 2x as fast (I don't remember if
I tried with bash1 or bash2). Plus, I think it's a lot more familiar
to admins and users used to Solaris, AIX, etc, and they don't have to
modify scripts written for it (provided the other commands are used in
a compatible manner). That's why I chose it as the default shell for
LNXS, but now I'm finding a number of things (the kernel for example)
that depend on bash, so I guess I'll have to incorporate that now too...
I believe the original ksh93 is now available under and open-source
license, but I haven't tried it out.

mathematics, though she is still forbidden to resort to physics and chemistry.
