The dirname utility originated in System III. It has evolved
through the System V releases to a version that matches the
requirements specified in this description in System V Release 3.
4.3 BSD and earlier versions did not include dirname.
yes - for instance, Apollo supported BSD 4.3 and Systerm V
environments.
Scripts written for the latter could have used dirname, while the
former
could not.
(There are still hobbyists running Apollos of course - not I).
