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.
