Re: bug found from ls command

[PG]

ah, great!

thank you for the info. That helps me understand a lot. Now I see why find
fails. And perhaps it's not worth the extra computation time required to,
upon failure of cd'ing into the directory, trying to list it.

I still think there should be an option for find that one could turn on that
would do everything possible to find a certain filename.

Thanks for the explanations.
