Usually the reason I want to know this is that I plan to do something
to all the visible files if there are any, so something like this
will work using the builtin "echo" command and only require the
directory to be read once.

LIST=`echo *`
if [ "*" = "$LIST" ]
 then :   # no files - do nothing
else
 for i in $LIST
 do
 ....  # commands to process files
 done
fi
