So after that last reply I had a nice dinner, and came up with an
alternative that is more precisely what you requested:
Find . -type d | grep -i '/myDirName/mySubDirName/$'
This has the advantage that it is not subject to the imperfect
implementation of mixed-case support inherent to QSH (the -i flag sees
to that). Also, unlike the prior solution, it won't report false
positives (such as dir1/myDirName/x/y/mySubDirName). And finally
(perhaps more importantly), it makes you right about the need for
