The V6 UNIX Thompson shell has been ported into software, allowing users to access the original shell code on modern systems with enhanced functionality.
Together, sh6, and glob6 provide a user interface that is backward compatible with the Sixth Edition Thompson shell and global command, but without the obvious enhancements found in osh. The original Thompson shell was principally written by Ken Thompson of Bell Labs. Additionally, the software package includes several shell utilities such as if, goto, and fd2, which are all ported from Sixth Edition UNIX.
The looptest utility is packaged separately, providing users with a simple way to script count-controlled shell loops. It is important to note that the Thompson shell's command language is minimal when compared with more recent UNIX shells. However, since the Thompson shell initially set the stage for basic UNIX-shell functionality, all standard, commonly used, current UNIX shells still have a great deal in common with it.
Furthermore, the osh project even has a Gophersite, which is an added bonus for users. Overall, V6 Thompson Shell Port is an excellent software package that provides users with enhancements and backward compatibility to improve their overall experience.
