[Orca-users] Stopping 'file did exist and is now gone' message(s).

[isaac r.]

Blair, et.al, -

Point well taken.

See the attachment. Its an improved "one-liner"
that checks for a file with ANY extension.
The "time" hour check is gone.

Explicit compression extensions (.gz,.tar.Z, etc. are
a breeze to customize.  By  the same token, I have not
done that because  newer compression methods
might become available and you probably don't want to
have to maintain this segment of code WITH ALL
possible
compression methods, especially every time
there's a new compression algorithm with a new file
extension that makes the headlines ...

Give an attachment a try.

What I noticed is that unless you have a newer
(not sure which exactly) version of Perl,
glob() appears to complain if it does not
evaluate to true.

Perl 5.8 (again, might've been fixed earlier) silences
glob () even if it fails - [behaviour that's to be
expected] 

Thanks and regards,
-I
