ksh: Checking for file existence

[Ross Druker]

Of course, after posting this, I walked away for 20 minutes, then
came back and thought of a simple way of doing this.  Forgetting
about the "test" command, doing

if ls *.data > /dev/null 2>&1

returns true if any files exist and redirects standard out and standard
error to null.

But I'm curious as to whether there's any other way.  Sorry for the
wasted time if not.
