- The Schily Bourne Shell was derived from the Bourne Shell sources from
- OpenSolaris. The Schily Bourne Shell is actively maintained and
- enhanced on a regular base. It can be compiled into three variants:
- Non-POSIX SVr4/OpenSolaris variant (obosh)
- The portable but not extended variant obosh allows script
- portability testing. Most scripts that run in the old Schily
- Bourne Shell will run with any Unix shell that is still in use
- since 1990.
- Minimal POSIX compliant variant (pbosh)
- This version implements the minimal set of POSIX features and
- this version is always in strict POSIX mode. The features are
- similar to the features in dash, but since pbosh supports multi
- byte characters, it is really POSIX compliant. The pbosh
- variant allows script portability testing aginst the POSIX
- feature set.
- The POSIX compliant extended variant (bosh)
- This version has been verified to work as the system shell on
- Gentoo Linux and OpenSolaris (SchilliX). The enhanced Schily
- Bourne Shell (bosh) implements many features that are missing
- in the OpenSolaris Bourne Shell listed above.
