Strange chmod permissions?

Hi,
I'm looking at some Python code and I saw a very strange like like this:

Code:

---

os.chmod( filename, 33152 )

---

WTF?? I've never seen 5 digits in a chmod permissions number. What exactly does 33152 mean?

You probably need to convert it to octal to make sense of it - it's 100600
User rw only, and some kind of "sticky bit"

The 100000(octal) bit specifies "regular file." I wasn't actually aware that you could manipulate that bit via chmod(), but who knows.

A mode of 10xxxx means it's a regular file.

From /usr/include/linux/stat.h:

Code:

---

#define S_IFSOCK 0140000
#define S_IFLNK  0120000
#define S_IFREG  0100000
#define S_IFBLK  0060000
#define S_IFDIR  0040000
#define S_IFCHR  0020000
#define S_IFIFO  0010000

---

I imagine that chmod(2) only looks at the 4 least significant octal digits.
