Okay ... I'm assuming ksh93 allows this construct:

	[ -f * ]

where as pdksh (which I think is based on ksh88) doesn't like it. So change 
the test to this:

	[ "`ls`" != "" ]
 
make sure you get the quotes right (those are backticks inside the double 
quotes). And give that a whirl; that should be universally supported right 
down to bog standard sh.
