Dirname - kdirname

Here is the Korn shell version of the Unix dirname command. It returns a pathname minus the last directory. As in kbasename, the substring feature does all the work.

					#!/bin/ksh
					#
					#     kdirname - Korn shell dirname
					#
					# Check arguments
					if (($# == 0 || $# > 1))
					then
					print "Usage: $0 string"
					exit 1
					fi
					# Get the dirname
					print ${1%/*}
