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.
