Good evening,

I was wondering if you could recommend certain shell-implementations.
Now, the reason why I'm asking is that I checked out some of them and
the according POSIX-specification[0] and wondered how much work it
would be to reimplement it and, of course, if there is any reason to do
Busybox's ash-implementation[1] for instance "only" adds up to around
20k LOC. dash[2], a fully POSIX-compliant shell, has less than 10k LOC.

Reading the source code I discovered lots of cruft, but learned a lot
about how a shell works internally.

The main issue we are facing today are the bashisms in many
shell-scripts, which basically override POSIX-compliance.
However, I mostly face these issues with rotten code and utils for
software relying on auto*hell (hopeless).
For everything else, there's the useful program called

Now, what do you think? Is there any shell to recommend as suckless or
do you like the idea of implementing it as a new project?
