In fact there used to be a /com/wd under AEGIS before SR10.

At SR10 AEGIS processes changed to the UNIX single program per process model.
An external wd command would have forked a process from the shell, changed
the working directory in the new process space, and then exited back to the
shell where the old working dir is still set. This is exactly what happened
at prior OS releases when you were in a UNIX enviroment and used "WD" instead
of the shell intrinsic "CD" to move the directory pointer. 

Many old AEGIS people use to take advantage of the fact that a program could
change the enviroment of the parent. Not that this was a good practice, but it
had lots of uses once I found out the rules had changed from other systems I
had worked on.
