[Fwd: Re: perl test fails]

[Rob Clack]

Well I thought maybe I'd better just try setting $CYGWIN, even though it 
didn't seem relevant (I don't  have "..problems with NT shares or Samba 
drives..", since the script reliably breaks when run from a local, 
non-shared drive) and indeed, it made no difference.  Unless there's 
some special way I should be setting it.  I just entered 
CYGWIN=nosmbntsec at the dollar prompt.

OK, so if I assume by the silence that -x is broken, can anyone suggest 
how I can determine in a perl script whether or not a file is executable?

Thanks
Rob

Thank you Igor.  However, I've now read the entry on smbntsec and it
doesn't seem relevant.  (Was a useful exercise in itself, since I didn't
know about the CYGWIN env var either ;)) I don't have a problem on the
Linux box, only on the NT one. And it doesn't matter whether I'm running
the script from the networked drive or from the local hard drive, I only
get the error under Cygwin.

So far it keeps looking to me as though Cygwin is broken.
