That's also a possibility. You can use cat to tell the difference
though.. Here's a "ls" shell function that knows the difference
between an empty directory and one it can't read. Unfortunately, it
requires cat, whereas plain "echo *" is done without forking:
ls () { cat . > /dev/null && echo * ; }
