Hi,
This is probably a windows problem, but here goes:
I'm observing a weird behavior in chmod. Basically, it looks like
removing the write permission for everyone on a directory doesn't prevent
the owner from deleting the files in that directory (which is inconsistent
with other unixes). What's really weird is that the Windows permissions
on the directory actually look correct (i.e., disallow deletions;
screenshot attached). The file's permissions allow deletion, though.
Below is a session log. Can anyone make sense of this?
Oh, `uname -a`="CYGWIN_NT-5.0 PECHTCHA 1.3.12(0.54/3/2) 2002-07-06 02:16
i686 unknown", OS is Win2k SP2, Cygwin version is 1.3.12-4.
