- The minix shell (adds just 30k) is quite complete and handles things
- like for/do/done, case/esac and all the things you expect a Bourne
- shell to do. It is not always pedantically correct about Bourne
- shell grammar (try running the shell testscript "tests/sh.testcases"
- on it and compare vs bash) but for most things it works quite well.
- It uses only vfork, so it can be used on uClinux systems.
-
msh is deprecated and will be removed, please migrate to hush.
If there is a feature msh has but hush does not, please let us know.
