probably some available that don't, or you could switch to a different

Right you are !
I took a closer look and see that there is a file

Without an MMU, userland constructs such as fork()s and certain kinds of

constructs in the absence of an MMU, it won't work either.

Actually, calls to fork() can be compiled, but it is a

Bash will work with uClibc, but it needs an MMU.

I don't have one. OTOH, I don't understand. uCLinux does not handle the
MMU and a user land program can't do that on itself. So it should not
matter it any MMU hardware is present.

you can write scripts and
run them in sash, but it does not support input/output redirection nor
parameters, which limits their usefulness significantly.
OK I do understand now.
I usually use busybox msh, since that does support all of that, but it has
less integrated commands so you need
